In this video (Episode 1) I will be explaining how i modified a pair of Yamaha FZR250RR crankcases, barrels and heads from four cylinder to six cylinder increasing the displacement to 374cc and naming it the RC374. I also talk about how I converted the standard wet clutch to a dry clutch. My aim was to make a 1967 Honda RC174 (298cc) replica that looks and sounds like the real thing. I made the whole bike in 2018.
