I did have a similar post about this but I wanted to update... this bog/ sputter I'd really bothering and def would like friendly advice. My bike is leak free 100% holds 7 psi and does no drop at all. I did the test twice. Compession Is 120-125 psi, I replaced both crank seals still nothing. Set floats and have jetting close. Reeds are a couple weeks old and a fairly new and checkout ok.. I'm aiming towards stator or coil ????? What do you guys think.
