mybanshees2fast4u Posted May 4, 2006 Report Share Posted May 4, 2006 I bought my shee from NJ and i live in maryland. I have the motor apart because it melted a piston (i think an air leak caused it to lean out but i am not sure). Maryland is at sea level, i am running full fmf system, a uni filter and proform plate, 24:1 premix with yamalube, and the main jets that are in it now are 260. I think i need to set up but to what size. It is about 65-80 degreess now and summer is coming up and it will get up to 100 somedays. Since the main jets are different than stock i m guessing it has been jetted b4, so should i just buy individual jets or what kit should i buy.

Please Help 511777[/snapback] Try some 300 main jets if you have the lid on. Take the lid off and try some 330's or 320's. 260's are what fmf usually includes with their pipes.

dajogejr Posted May 4, 2006 Report Share Posted May 4, 2006 24:1??? I'd try leaning that as well, 32:1 or 40:1...more oil doesn't always mean more protection... As said...300 would be a good safe starting number. You didn't mention your elevation...any idea what it is? Quote Link to comment Share on other sites More sharing options...
