cheetah cub jetting


Recommended Posts

Curious where to start on a new cheetah cub setup?? I have the 65mm bore stock stroke setup built by Jeff Wendorff at F.A.S.T. Racing, consists of a Pro Design Head w/ 18cc domes, 34mm Mikuni flatslides, Boyeson reeds w/ stock ported reed cages, advanced timing, clutch work, wiseco crank, CPI inframes, wiseco pistons, etc....Let's hear where to start...also I ride only at Little Sahara in OK....thanks

man if only you had keihins i could really help you out. are the aftermarket mikunis using the same jets and what not as the stockers? if so i would start at like a 360 and work from there. cubs like fuel thats for sure. also, what kinda riding are you doing with these cylinders? dragging mostly? if so id lose the 18cc domes and get some 21cc domes cut. let that motor rev. those 18cc domes will drastically affect the top end. i know jeff knows his shit but my bros FAST cylinders use an 18cc dome and my old setup was damn near the same except with 21cc domes and mine would outpull his on top even with lower gearing..

Yes, the 34's use the same mains as the stockers, Jeff recommended around a 350 but I thought maybe someone on here had the similar setup...My riding will be half and half...duning and dragging...thanks

Actually I'll probably have 38's on by the time I get her going on the dunes anyway, so if anyone knows a little more about 38's please add your input...any info is helpful....thanks again

Mine is a 68 bore 4mil with 38's... 55 pilot/ 160main, DGK needle in middle postion that's what Dan from Patriot recommended for mine... Should get you somewhere in the ball park though.

I've talked to Calvin Pollet himself ( the designer of the cubs ) He told me himself that 34's where about the smallest carbs he'd ever use on any of the cub setup's even with the stock stroke (54)....so if ya don't believe the 38's will work even better...then call the designer of them and let him tell ya a little tid bit about them ....laters

what do you want feedback on? theres prolly only like 4 guys here that even have cub cylinders and most are prolly not running those carbs. most people here have said to run keihins but you want to run mikunis. looks like you got some feedback right there.
