hi everybody, long tie lurker on here but i decided to finally make an account because im at my wits end on this motorcycle. so far ive cleaned and rebuilt carbs with new gaskets and float needles. set float height. i thought the ignition was the cause but ive got it spot on right now.
bike is a 77cb750f2. when turning the bike over it just puffs air out of every carb mouth and you can physically feel it doing it.
i have spark and fuel. ive checked and double checked the valves and they are set at 0.002 and .003 just what the manual says
