i'm thinking that one of the reasons i can't get more rpm's is the 170's might be to much fuel for the motor to spit out, anyone else ?

You are right IMO Doug
are they not supposed to be 165's? That is what I have in mine.

In extremeley cold condtions and with the Whiteknuckle GP1 exhaust, I used 170 main jets once. It was 0 to -10F.
