On my 2nd bike it started bogging down at wot I bought a couple of jets from sick bike parts and put the clip on 2nd notch from the top bike ran great! Now its doing the same thing I pulled the head and noticed cylinder head studs were loose but I snugged them up put the head back on, and it's still bogging down at WOT its gotta be an airleak. I guess I'll have to get some carb cleaner and fire it up and spray at the base gasket and intake manifold and see where the airleak is,kid at the bike shop where I bought the kit says the cleaner maybe hard on the seals but I can't think of another way to find the leak? Anyone got another way
