so ive been trying to chase down my issue with having the bike run rough between 1,200 and 3k rpms. it only does it when it warms up. i replaced the FPR and that didnt fix anything... so i made sure i had good ground to battery and i do. next thing i checked i seen 2 vaccum lines that were disconnect from the fuel tank, i think they are for overflow lines.... the spark plugs were replaced about last year. ive ran sea foam through the tank and still and didnt make a difference. I havent ran it since the overflow tubes were put back on the fuel tank... any one have a clue as to what it could be?
