Just curious what u guys recomend for main jet sizes. I have read a few things saying that once u get up to a stage 2 and 3 u should be running a 170 to 175 in the motor to keep from running it lean and floating a valve. Or does it all depend on each motor. I currently have a 165 in it but bought a 170 and 175. I havent had the motor out to really see if its running lean on a 165 Thanks

run it wide open and pull the choke if it speeds up put a bigger jet if it slows down your good

or stays the same speed

thanks man ill give that a try.

maybe someone else can give a lil input im not a certified mechanic

Fowl...you should be fine with a 165.
