Hey guys I just built a new engine on my shee. 421 servo cub 4 mil stroker crank,35mm keihns v force 4 reeds aluminum manifold. Trinity stage 4 pipes and silencers, trinitt cool head 21cc domes, race fuel mixed at 40:1 Everything was bought new for the build. I started the bike let it run for 15 min for break in. Then started it again this time the right side seems weak not as much smoke as the left side. Compression was 150 lb per side there was spark on both sides. Fuel air screw was at 1.5 turns out to start. I stopped running in until I can diagnose the problem, it was not driven yet. I appreciate any help. Im sure someone posted this problem before I was trying to have it running right for the weekend but I'll settle with running right.
