iwas wondering if there is truth in dynojet using different numbers compared to factory jets?my modded wolverine runs good with a yamaha 155 main jet and stock needle on botoom clip. i was wondering if i could get moer out of it with a bigger main,i heard you can go up to say a 165 try it see if it stumbles then go to a 160 and see if it stumblesand so on ?i have a je 10/5/1 piston 40 over a web cam and some porting .
