I’m guessing it has something to do with the Delkevic full exhaust and being de-catted? I have the Pcfc and am wondering what changes I could maybe make to smooth the bike out from 0-4,000rpm? As soon as I hit 5k the bike takes right off and runs like it should. I tried addind fuel to the first two trim settings on the Pcfc and that didnt help. Maybe 4 degree timing advance wheel???
