Some guy put a mixture of oil and gas into my tank like a fricken idiot I told him not to. Now the bike smokes and chugs and takes forever to warm up. Is this bad for my engine?? When I go to do a wheelie or rev the engine it bogs like hell and smoke comes out. I didn't think there was a lot of oil in there but its been weeks and I've gone through a tank of gas and its still burning oil? What should I do?
