I wanted to keep the original “vintage” look while increasing the performance so here is what I have done.
Rebuilt top-end using stock OEM piston kits.(.25mm).
Replaced main crank brgs and all seals in engine.
Slightly modified/matched ports.
Machined cases/cylinders to accept larger RZ350 reed cages.
TDR one piece reed pedals..
Carbs have been bored to 27.5 mm.
Installed “Mad-Beaver” air filter kit(removing stock air-box).
Intalled “Jolly Motto” expansion chambers.
I have spent MANY hours re-jetting….it runs AWESOME!
Researched options first then installed ’93 Yamaha FZR600 frt.end/frt wheel(17×3.25)/r wheel(18×4)with “Race Tech” emmulator kit,Metzeler radials,HH pads,stainless lines(all parts were rebuilt/polished/powder coated,to the tune of $2400 before install)I chose the FZR stuff because it is a direct “bolt on” and you dont have to modify the oil-tank and plastics to clear the forks.VERY clean swap.
FZR speedo which is the perfect twin only is MPH instead of KMs.
Digital temp gauge.
I have only riden the bike about 5k miles since rebuilding everything.
This one has great detail to go with the listing and appears to be owned by tech who cared for his baby. Think it’s a good buy?
