Hey yall i just got a 86’ qt50 i believe all stock still. Runs great for the most part but once i reach about 25mph i start bogging. I’ve messed around with the carb intake a bit but doesn’t really seem to make a big difference at top speeds. Ive been running a premix this first tank just cause i wasnt sure if the injection was working (still not totally sure but i believe it is working atlest a slow drip cause its seems a little smokey) anyways where should i start looking to resolve this if its not a air intake issue? Could running oil heavy be the problem or should i just jump into carb rebuild? Thanks yall! So hyped on my purchase, this thing rips even at 80%!
