Thought i would see what you guys think about this. Got my new Boysen carbon fiber super stock reeds put in and the Fmf power core two silencer and fatty pipe on , re-jet carb to 270 and the bore on the motor is .020 the air box lid is on. I did not do a plug chop yet but 2 1/4 turn out on the air screw is where it want's to run. If i turn it more to the standard 1 1/2 turns it will bog out or won't rev up like it hits a rev limiter. Is this a problem or what do you think if you guys think it is a problem i could toss the 260 main in and go at it again.
