ok i have a 92 gsf400 and i just cleaned the carbs and now as before still not running right. with the air box in it seems its not getting enough air then i take it out and and it runs fine but at 8000 rpm it dies down. it doesnt do it all the time. but i cant really drive it because of this all it seems like to much gas is getting to it but im not sure never messed wit bike carbs before. can someone please help me?
