I have an 85 250r that i just put back together. I have an fmf pipe and silencer, boysen carbon fiber reeds in the stock cage, I had it ported, and I am running a 35 mil airstriker carb. I have a 160 main in it now and a 60 pilot. I have a feeling that the pilot may be too big. I have a 55 pilot laying around that I could put in. I am having trouble to get it to idle. It idles really low right now. Should I swap the pilot jets.

Have you adjusted the idle mixture screw, or the idle speed screw?

60 pilot is way to big for a 250r,,, i am thinking closer to 50 or less
