750 BIG BORE KIT FOR FIII 600
We have developed a 750cc big bore kit for the FIII which greatly increases the torque and HP of the 600 making it comparable to the Mach Z in performance. We suggest boring the carbs to 40.2. The 750 kit produces 143 HP at 8400 RPMs with stock pipes and 152 HP at 8600-8800 RPMs with Crank Shop pipes. The kit consist of resleeving the stock cylinders, porting, base work, head machining, and pistons. The labor to disassemble, clean, and assemble the motor is not included in the package price.
