Legend: 1985 Yamaha RZ 350

Every iconic bike tells a story. In the case of the RZ350 – the last of the factory imported two strokes into all 50 U.S. States – the story is one of evolution. The RZ (or RD350LC as it was called in other markets), was an evolutionary beast that began with the RD series of the early 1970s. But the RZ took the parallel twin two stroke concept much further, by adding liquid cooling and a trick exhaust port power valve to widen the power band (YPVS), not to mention the catalytic converters in the pipe trick. This particular bike has a story as well. And far from some adverts we see where the owner says (or knows) nothing about the bike in question, today’s seller has written a ton. I will let him pick up the story.

1985 Yamaha RZ 350 for sale on eBay

From the seller:
Step 1: The purchase
My desire for a top of the line RZ350 started years ago, but in early 2014 one came up for sale 800 miles from home. My wife and I jumped in my truck and arrived in Missoula MT to pouring rain and freezing temps. “perfect bike buying weather”. The seller was short on words, the bike was complete but the wheels were seized from sitting and the buyer all of a sudden “couldnt find the paperwork.” Are you kidding me? After we drove 3 states to come buy it? So i said I’m paying you 300 dollars under asking until you can find the title, long story short, he blocked me and I never heard from him.

More from the seller:
Step 2: Contract the builder
Reach out the best 2 stroke tuner/builder I know at the time. His name is Troy Gessner out of Bellingham, WA. If you’re ever curious, go look at 125GP records, his son John, had all of them. His dad is a 2 stroke genius and was a meticulous engineer type mechanic. Never cuts corners, never says “that should be ok”. While every other GP125 would have some sort of a mechanical or seizure, John and Troy went 2 years with 2 mechanicals, and both were electrical related, not catastrophic mechanicals. At any rate, I reach out and he says tell ya what… You get that RZ, and I’ll do a frame up, cases up build for you, at half what the shops would charge. Deal. He’s recently retired, and excited to work on a 2 stroke bigger than a 125GP Honda. We talk about the best route and without going into politics, WA state is real bugger on VIN/No title issues. So we result to buying a frame and title off of Ebay from AZ. Frame arrives to Bellingham, i take paperwork to DOL, we get title in my name, the DAY we recieve the proper title, clean title, Troy got to work. Please note, we are building a true Spec II Racing version of the RZ350. Spec II oem bodywork, Spec II windscreen, Spec II crankshaft rebuild and weld up, Spec II pipes. THIS IS A NON-MATCHING FRAME/ENGINE. Since this is a fun Spec II Yamaha version, the vin on the frame and the vin on the engine should absolutely not matter. It surely didnt to us. This is an aftermarket build with todays components and goodies almost everything upgraded to be better.

More from the seller:
Step 3: The build.
When I tell you that this was a nut and bolt restoration, I’m not saying it was “kinda taken down and slapped together with new top end and pistons” I”m talking every wear item, every nut bolt seal was ordered through Yamaha. We paid hundreds of dollars to have oem fasteners, nuts bolts springs, seals, all OEM. Here’s the short list. You will recieve with the bike, a build book. See final photo, its 1 page of your build book where Troy outlines every detail from every day he spent working/building the bike.
Entire bike disassembled down to nothing. Everything in the engine was in working order except the cylinder head showed some bad gas pre-detonation wear, so we waited for a month for a perfect OEM Cyl head to pop up on ebay.
Crankshaft sent to Spec II Racing to Gary for rebuild and welding.
After tearing everything down we realized after talking to the painter, the only way to get that specific decal kit to look right, is if its on the bike. Trevor Beckman at FlexiGlass in Vancouver Canada, needed the bike almost like it was going to be done. So the only way around this was to put the bike back together, without the engine and drive the entire bike to him across the border. Troy did just that. The Spec II edition decals were applied to the bike on top of the white paint but underneath the clearcoat, just like it should be. the paint/clear looks like a factory job. After paint was done, Troy went to pick it back up, and carefully disassemble it, and put the bodywork off to the side. Ducati red and bright white. Are those factory colors. Nope. Do they look correct, yup.

All holes in the frame were cleaned and die tapped. The frame recieved new head bearing races in the frame (and bearings upon reassembly)

More from the seller:
The internet says that the rear shock is “not repairable” Troy brought the rear shock to KFG Racing. You may have heard of them, they’re the #1 suspension shop on the westcoast. KFG drilled/tapped the shock, recharged it, and resprung for a 200lb rider. No more saggy bike with worn out 35 year old shock for a 140lb rider. Even better, when you buy the bike, if in 10 years it feels soft. KFG can service it again for you, like a current day sportbike shock. The front forks were torn down by Troy personally and rebuilt with new internals and oil. The calipers were nasty. He tore them down and rebuilt them with new parts and new brake pads. The wheels and calipers were in great shape. The bike only had 15k original miles.

When Troy reassembled the transmission, all the small washers, seals, springs, pins, bearings were replaced. Everything reassembled like a tech would in 1985. Shifts like a new bike.

Engine wise, the engine is stock. No crazy porting. No changes to compression. Troy says “we want this bike to last. We want it to run prime, and behave on the street.” So I agreed to that for sure. We decided to install VFORCE3 reed cages for some added mid-range power. Rebuilt oil and water pump. New bridgestone tires.

Things not restored: seat/seat cover, wheels, calipers, tachometer cluster, bar end mirrors kept.

Amsoil Dominator 2 stroke race oil injector used for break-in. Coolant topped off, Yamalube oil for trans. Bike runs like a dream, pulls hard, shifts hard, sounds great. Has a nice crackle to the pipes 🙂

More from the seller:
Lastly……Step 4: The negative. (small stuff!)
Ready for the bad news? (I told you. No surprises. Thats not how I sell)
Upon getting the bike back together, I went up to Troys house and he says well Darren the bike is back together go ride it. But we do have a ever so slight (a drip an hour) leak near the petcock. so we wipe the drip and go for a ride. Bike is great, I pay troy for his time, and i’m on my way home. I get home unload, go ride it again, I go for a 35ish mile ride, I’m as happy as a clam. All the electrical works, bike pulls, corners, shifts, and brakes, like a bike 20 years, 30 years newer! The gauge cluster still has a small chip out of the lower right side. very minor, see photo. I’m all smiles…. Until the next morning. I head out and the shop has a strong gas smell. I find a grapefruit sized puddle of fuel on the ground. I realize the tank leak is a bigger issue than I first realized. I touch the area up UNDER the bottom of the tank, if you know RZ350’s, they have a section of a half an inch that is LOWER than the petcock. A horrible design as all RZ owners know. I didnt catch it, Troy didnt catch it and VERY sadly, the painter/sander, did not catch it 🙁 Now we have fresh paint, fresh decals from australia, on a tank that needs some sort of a repair. I am no body guy, but i did what I could to try to fix it. i used an exacto knife on the fresh paint up under the tank maybe 1″? (i know, teeth gritting to read that) and I applied a thin line of JB weld. It was a temporary fix that worked for a few months, but it didnt fix it. I rode it 1 more time. I’ve had the bike entered in 2 motorcycle exhibition shows, and it one that gets the looks. And now the embarrassing part. A small dribble lead to the bike being parked and “i’ll deal with it later.” Its 2021. I opened Troy’s book to read off some of the meticulous notes, and it starts off with “15 May, 2014″….. I just shook my head. I have a family now, and I’ve decided to split ways with the bike. So you know the entire story. You’re getting the best of the best, frame up, engine up, suspension up type bike. You’re getting bodywork that is as rare as a white unicorn, a windscreen that is no longer in production, and pipes that are hard to find. BUT you will need to repair the slow leak gas tank. At this point you will need a new battery. The bike has approx 50 miles on it.

The long and short of it is that RZ350s are money these days. Non running junkers are going for what great riders were going for less than a decade ago. Today’s seller spent a lot of time (and money, undoubtedly) to build a very clean example of a neo-RZ – keeping to the original theme, but making some interesting and cool modifications. Clearly the Spec II parts and pieces approach works from a period-correct perspective. The pictures show a bike restored to a very high standard, but the tank leak is definitely unfortunate. So, too, is the damaged bezel given the overall condition of this machine. Which brings us to the asking price of $15k. That is big money, although a completely restored stocker might pull it off. The seller appears to be open to offers, so check out all of the details here and give it some thought. Good Luck!!

1/2 Pint Performer – 2000 Cagiva Mito 125

This Mito sold while we were preparing the post, but might be a good warm-up for a Featured Listing next week !  -donn

If all you had was a 3/4 front view from across the street, it would be easy to mistake Cagiva’s Mito for a lovely red 916.  Quite a bit rarer than it’s full-sized inspiration, this 125 has had some serious attention, just a handful of miles, and boasts California reg.

2000 Cagiva Mito for sale on eBay

Introduced in 1989 for the European junior market, Cagiva had great competition success with the Mito, which had 34 hp on tap in the 2000 model year.  Legendary designer Massimo Tamburrini re-styled the bike in 1994, giving it a knife-edge fairing, winged tank and monoposto seat fairing reminiscent of the Ducati superbike.  Sales of the Evo II generation weren’t hurt by the 6-speed transmission, 17-inch Marchesini lookalike wheels, asymmetrical alloy swingarm, and 40mm usd Marzocchi forks.  Even the brakes are adult-sized at 320mm, but just a single front disk.

This collector bought his Mito new and didn’t leave well enough alone, but made some significant upgrades to the powertrain.  Condition is immaculate and shows just over 1,200 miles.  A great explanation of the engine work from the eBay auction-

This 916 Ducati look alike is a Cagiva Mito 125 2-stroke, the same type of motorcycle that Valentino Rossi started his racing career on at a young age. Back in the day they had a 125cc class of highly modified 2 stroke street bikes for upstart racers in Europe. Cagiva was the bike. Cagiva even sold an entire massive hop up race kit to convert these little rockets into race bikes. I was able to obtain many of these upgrades and incorporate them into this bike and maintain its street legal style. First thing I did was update the cylinder. I purchased a Polini 160cc kit. Now the Italian company Polini is famous for their products, but there 160cc Cagiva kit lacked a little quality. I sent the cylinder to England to my old friend Stan Stephens. He stripped and re-plated the cylinder with a more quality ceramic plating using the proper tolerances that Polini seem to lack. He then lightly cleaned up all the porting and milled the head for the larger displacement. I added a larger manifold to install a 34mm Dellorto flat side carburetor with carbon reeds. Stock Carburetor was a 28mm. Installed the Cagiva racing kit pipe along with the fork conversion, racing kit clutch springs, Carbon carrier disk with Titanium bolts, 415 chain conversion, aluminum sprockets, racing wind screen, Steel braided brake lines, Tail Tidy, Carbon Front Fender, and kick starter. This bike came with electric starting but I removed it to save a massive amount of weight of the starter and the big metal gear attached to the flywheel. The race kit comes with a kick start shaft and gear with a removal kick starter. But to sell it I put the electric starter back on, but still have the backup kick starter installed. I then powder coated the rims white from their original ugly colour. Added Michelin pilot tires.

Performance wise the 160 Polini kit didn’t really give it much more top end but a lot more torque. I’ve had it to around 115 mph with maybe a few RPM’s to go. Depends on the gearing, weight of the rider, outside temperature, wind, etc.. It will get up to 100 mph remarkably fast for a bike its size, and corner like you’re on a rail.

This bike only has 2,000 original kilometers or 1,200 miles on it and is 21 years old !  Maybe half of that since all the upgrades. The bodywork, cases and metal look like brand new. Bike never been in harsh weather. Stored in a climate controlled garage in sunny California. All the electrical such as lights, turn signals, horn, work without an issue. Oil injection is still intact. Just put in a new battery and did a fluid flush. Included with the bike is a new Polini 160cc top end, additional gearing and the stock exhaust.

Not many riders can keep the Mito on the boil to make the pace it’s capable of, and less might be inclined to sink the slighty-used-superbike ask into a 125.  But it’s a collector’s joy, a total rarity, impeccably prepared and ready to rock.  If that collector is you, we’d like to hear about it.

Gammarosity – 1987 Suzuki RG500 Gamma

Prior to the turn of the century, 500cc bikes were the ultimate Grand Prix class and Suzuki were regularly on the podium and occasionally the top step.  Here’s an RG that has been more carefully tended than most bikes, and pushing 190hp per liter.

1987 Suzuki RG500 Gamma for sale on eBay

Suzuki had won back to back championships in 1981-82 with the RG500 racer, but didn’t introduce the replica until 1985.  It was worth waiting for, with a complex rotary-valve square four engine claiming 95 hp.  28mm Mikuni carbs look into the engine from the side, and there’s only a kickstarter.  Suzuki’s automatic exhaust control tailors the downpipe volume to rpm, widening the torque band.  Though the chassis tubes are small section, they’re beefy and connect up to a massive steering head, all alloy.  “Deca” brakes have ten pistons, per bike – eight on the 260mm front discs and two on the 210mm rear.  Solid looks are partly due to the wide powerplant and tall 90 series tires.

From the garage background, this gulf coast owner is a real Suzuki fan, with a passel of dirtbikes thrown in.  The RG500 is in exceptional condition, with only one short fairing crack in its original good looks.  Naturally a grey import, but no ownership or maintenance history is offered in the eBay auction:

7,906 miles all original. Runs great. Speedo is in Kilometers.
Tail fairing has 1 small crack above left exhaust pipe.

Suzuki bowed out of a factory effort in 1983, but still supplied RG500 developments to the H-B and Heron teams.  U.S. rider Randy Mamola had been on the podium in the last few races of 1982 with H-B, but factory riders Uncini and Reggiani went to H-B’s first string for ’83.  At this point in race replica, square four, or two-stroke road bike history, the time to watch and wait may be behind us.  Just three bidders are testing this auction for the reserve, and if you intend to make some history with an RG500 this looks like a great example.

Meet You Half Way – 1979 Yamaha RD400F Daytona Special

To celebrate Kenny Roberts’ 1978 Daytona win, Yamaha styled a distinctive final-year model with all the air-cooled improvements since 1973.  Here’s an Ohio native that shows like it has 1,2oo miles instead of the 12,000 the odometer says.

1979 Yamaha Rd400F for sale on eBay

The RD400F is just bit more grown up than the original RD350, though it shares the wheelbase, 28mm Mikuni’s and kickstarter.  Along the way it acquired five additional ponies, alloy wheels, capacitive discharge ignition, and a wider rear tire.  Its additional 35 lbs. meant 25 more feet in the 60-to-zero test, though braking was identical with front and rear 267mm discs.  Changes to the engine’s porting and an internal bypass improved rideability and lowered emissions, along with an almost Suzuk-ish shroud on the head which improved the noise signature.

Probably looking better than it did on day one, this collector’s item has been restored and polished to a fair-thee-well.  Since the Daytona is an exercise in white, black and chrome, it’s naturally photogenic.  Expert readers will have to weigh in on any discrepancies.  Comments from the eBay auction:

Only 12,122 miles. Clear title in my name. Numbers matching with all the 2VO stampings also. This is a beautiful survivor. The body set has been repainted with the pearl white to perfection. New seat cover. Tires are also new. Gas tank is clean metal inside. Everything works like it should. Starts easy and runs and rides great. Pulls hard and smooth through the gears just like it should. This is stunning survivor.

When the last RD400 rolled out of the showroom, Yamaha was in the middle of a staggering 12 year run of luck in the Daytona 200, and Roberts also won the last of that streak on his YZR680 / OW69.  Yamaha brought back the two-stroke twin ( in a water-cooled form ) in 1983, but took it offshore after only two years.  The sound, simplicity, and lighter weight make the air-cooled RD’s worth pursuing, but rather few are in this remarkable condition.

Out in the Yellow Paint – 1985 Yamaha RZ350

A classic in part because it’s the last year of U.S. imports, Yamaha’s Kenny Roberts edition typifies two-stroke fun.  Here’s a windy city example with low miles, excellent cosmetics, and Jim Lomas expansion chambers.

1985 Yamaha RZ350 for sale on eBay

Yamaha had their air-cooled 350 in the house since 1973, but liquid cooling brought more stable cylinder head temperatures and better all-round running to the RZ.  YPVS electrically tuned exhaust ports made for a wider torque band and 59 hp.  The RZ had Yamaha’s first perimeter frame on a road machine, in steel tubing with a racer’s drop-in fuel tank.  Other race-bred improvements like triple disk brakes and monoshock rear were making their way on to more popularly-priced bikes.  Yamaha’s day-glow GP race livery reflected their Marlboro sponsorship, but the AMA series speed block livery is adorned with Roberts’ autograph.

Apparently for sale by owner, this beauty shows just half of the 25K miles a lot of RZ’s have, with just a couple of paint chips to show for 36 years.  Throaty exhaust notes in the too short video posted – here –, and just a couple of comments from the eBay auction-

Kenny Robert’s edition, the most desirable year of the most desirable color combination Yamaha RZ 350. Very low original miles (12,647), clean title with owner of record since 1991 and matching VINs. Runs well, idles perfectly, fires up first kick and it was jetted for JL pipes.The bike is in overall in great rider quality condition, it has some very minor imperfections shown in the pictures below. The bike sits in my climate-controlled building and is available to view anytime.

Winning two Grand National Championships, and three World Championships ( and being runner-up in each once ), Roberts is a champions champion.  There have been other yellow and black comemmoratives since the RZ350 was legislated out of existence, but this is still number one.  For a fan of the man, the brand or the sport, a fresh-looking two stroke sportbike would be a great tribute to have in the garage.

New Lease on Life: 1991 Suzuki RGV250 VJ22

The Suzuki RGV250 Gamma was a significant model for the factory at Hamamatsu. Original conceived as a parallel twin, the RG evolved into the 90 degree v-twin for the VJ21 and VJ22 models before morphing into the 70 degree vee of the VJ23. A favorite of racers, street riders and collectors alike, the RGV250 spawned the successful Aprilia RS250 as well as several Suzuki-specific themed liveries. Of the rare graphical packages, the Pepsi was perhaps the most rare, but the Lucky Strike livery continues to be the most popular. Today’s 1991 RGV250 VJ22 does not appear to have started life as a Lucky Strike, but looks striking after a much needed refurb (despite the lower resolution photos).

1991 Suzuki RGV250 VJ22 for sale on eBay

From the seller:
1991 Suzuki RGV250 M model. This an UNRESTRICED RGV250 VJ22

As shown in the before picture it was UGLY…. but has been transformed into a beauty.
New Lucky Strike paint job with four (4) coats of clear and a little pearl in the white areas.
Wheels stripped and powder coated white. New Dunlop Q3+ tires.
New Ohlins color upper fork tubes…NOT Ohlins forks but they look like them,,,however I added..
New Andreani Misano race fork cartridges with separate compression in one leg and rebound in the other.
New fork tube bushings (Racetech), Red SS brake lines, SBS brake pads, Sugaya street expansion chambers

More from the seller:
Calipers gutted and new internals installed with satin black caliper paint
New NITRON R2 fully adjustable remote reservoir rear shock
Tyga carbon fiber rear hugger and Tyga power valve covers with drains
Cougar power valves
Mild street porting and head work by Ed Toomey at Ed Toomey Designs. Renowned two stroke guru.
New 1st over pistons, rings, wrist pins, small end bearings and cylinder Nikasil coating.
Radial front brake master cylinder from a GSXR600, wave front brake rotors.
New Zeeltronic ignition controller with hand held programmer.
(If you don’t want the Zeeltronic I can put the original ECU back on. It is the upgraded 23D70 unit).
Carbs are clean and balanced. Carbs are the larger 34mm size
New Suzuki oil injection pump

Putting aside the sordid history that might have brought this bike down the road it traveled, the resto-mod approach with this particular example really works for me. This bike certainly looks a sight better than when the seller first acquired it, and there is no denying the visual impact of the Lucky Strike scheme. In addition to paintwork this bike has received some much needed attention to the chassis and systems, and now sports some important upgrades including suspension, exhaust and the all-important tuning to de-restrict the colony of bees and transform it into a hive of angry hornets. Figure 60+ HP from a stocker with the restrictions removed, and likely a tad more here if all components are working correctly together. Should be fun on a barely 300 lbs (dry) machine.

This bike is listed as “Excellent condition, as new, showroom condition” – although it might be fair to list it more along the lines of a restoration. And we should all be thankful someone is willing to undertake such a labor of love, as the world needs more of these bikes rescued and returned to glory. Not much action on this particular auction yet; opening bid is $5k USD with a reserve in place. There are a fair number of watchers on this, so perhaps everyone is sitting back and waiting for the fun to start. Check out all of the details here. While not completely original or stock, this restored and modded machine sure looks like fun. Good Luck!!

Out of Towner – 1986 Yamaha RZ350

Since the RZ350 was sold here until 1986, it’s relatively rare to see the fully faired rest-of-world edition.  Though this example isn’t currently operational, it shouldn’t take much to bring it back to the living – not to mention California title !

1986 Yamaha RZ350 for sale on eBay

For 1986, the RZ350 used Yamaha’s 347cc parallel twin with their electrically controlled power valve, and revised porting and combustion chamber helped make 59 hp at 9,000 rpm.  The lightweight rode on 18-inch alloys with air-adjustable forks and monocross rear.  A perimeter chassis and swingarm were executed in steel tubing, with triple disk brakes.  The full fairing was new for 1985, but 1986 saw a revised tail fairing which perhaps looked sportier in its simplicity.

Not seeming to be a dealer, this owner invites inspection at their home.  The RZ shows very well, with 14,403 km’s or a hair under 9,000 miles.  Finishes and plating indicate inside storage.  Nicks and dings keep it from being a real show bike but once it’s back on the road, it would be a smashing rider or riding resto.  Comments from the eBay auction:

The bike is the full fairing Canadian model that was imported here in the US and it comes with a clean CA title and non-op registration.  The motorcycle is in excellent condition and has approximately 14K Kilometers which is equivalent to just under 9K miles. As shown in the photos, the bike is in excellent cosmetic condition with only minor blemishes to the paint as shown in the last photo. 

The bike has been stored and was drained of fluids, so it will need a light service to get running including but not limited to a new battery, fresh fluids, and possibly a carb cleaning.  The motor kicks over with great compression, the throttle turns, clutch and brakes are working, inside of gas tank is clean, electrical is working, etc. so it should not take very much to bring the bike back onto the road. 

For anyone considering this bike as a collectors item or investment, the bike is a numbers matching (Vin to Engine) vintage motorcycle in mostly all original factory condition, this bike has not been restored but rather it has been on display and preserved for most of its life.

Can’t pretend to understand the RD / RZ / LC confusion, but the actual bike has made more incremental changes over the years and across continental divides.  Meanwhile the two stroke Yamaha fun factor is un-parallelled.  Bidding seems serious in this auction, with more than three days yet to run.  The new owner will have a distinctive RZ350, and will get a chance to know it better during the re-commissioning.

KR1S KR0S: California-Titled 1991 Kawasaki KR-1S for Sale!

Here in the US, the entire class of 250cc two-stroke sportbikes was long nearly impossible to come by and, let’s be honest, probably not much missed by the majority of the riding public. In a land of GSX-R1100s being ridden by guys who considered a mullet and wraparound shades to be adequate protection, the market for 45hp two-strokes was always going to be pretty limited. But if you were just the right kind of motorcycle enthusiast, it must have been excruciating to read about bikes like today’s Kawasaki KR-1S in the pages of Fast Bikes and other European magazines of the period.

It’s easier to get a number of these formerly forbidden fruits here these days, now that they’re legal to import. After all, the Honda NSR250R was in production from 1987 until 1996 so, if you’re not too picky about which particular NSR you get, it’s not really all that rare a bike in its home market: nearly 100,000 were built in total. But Kawasaki’s entry into the class is rare, even in Japan, and was only rarely seen outside its domestic market. And even then, just 10,000 were built between 1988 and 1992, the bike’s entire production run.

By the time the 90s had rolled around, Honda, Suzuki, and Yamaha had all shifted to v-twins, but Kawasaki stuck with a parallel twin configuration, with the engine hung completely beneath the typical aluminum beam frame of the class. Like every other two-stroke two-fiddy, the KR-1 was light, agile, and involving to ride. Technology in the hotly contested class was cutting edge, and Kawasaki brought their KIPS powervalve and a slick six-speed gearbox to the party. Power was officially limited to a government-mandated 45hp, but the bike was naturally capable of much more when derestricted.

There were three versions of the KR-1 available: the base KR-1, the KR-1S seen here that included wider wheels at the front and rear, and a few hundred examples of the KR-1R that featured larger carburetors and a close-ratio gearbox. Top speed was a frankly incredible as-tested speed of 139mph!

From the original eBay listing: 1991 Kawasaki KR-1S for Sale

A Very rare 17 digit frame (Australia) CA titled 1991 Kawasaki KR1S 250 two stroke bike. Bike is in excellent condition. Bike will come with a lot of NOS parts and engine parts as well. Feel free to message me if you have any questions thank you very much.

The price for this two-stroke unicorn is a steep $17,900. Is it worth it? Well that’s hard to say: if that Cali title is easily transferred and if that cache of parts is extensive, I’m sure it will be to the right buyer. You may have heard that there are lots of well-heeled enthusiasts here in California with more money than sense… If you’re interested, move fast: there’s just about one day left on this auction!
