The new setup is, Cheetah cub with mild port work 68 x 54 mm, i think it is a 392cc. I have an RK tech head with 19 cc domes. I am running v-force 2 reeds and 35 mm keihins with separate K&Ns. I have a k&T adjustable timing plate and lightened flywheel. I am running CPI small bore inframe pipes. I know somebody on here has this setup, all I can seem to find is info on a 4mil. Just need some info on a good place to start for Jetting and timing. I mostly run at 5000 ft elevation. I have also considered running about a 50/50 mx to get about a 100 octane if needed, Let me know what u guys think or any other questions.
