Help?

[exrider12]

It has a slip on Hmf exhaust, K and air filter, Air box lid on, GYTR 13:1 piston, and cam mod. The guy I bought it from said it needs to be jetted. All this stuff is brand new. He put it on and didnt use it.

Whats a good starting point? He says a 202 main and 55 pilot. Any input?

wow 202 main...im running a full hmf with a uni air filter with out air box lid and only running 175 main jet

Thats what I said. Then he told me that since it has the cam mod and high comp. piston it needed to be higher.

That guy is wrong on his jetting. I have full exhaust, different intake and filter, cam mod and 12.5:1 high compression piston and I am running a 172 main, 48 pilot, 3rd clip on the ncvq needle and 2 turns on the a/f screw. You won't need to go that big on the jets unless your carb is bored out bigger. Other wise I would start off somewhere close to what mine is and go from there.
