My bikes been running really rough it just doesnt idle right. it starts up no problem but then you have to keep blipping the trottle or leave the choke open. it also sounds like the bike is starving for gas even when holding the throttle open at a steady rpm, misses while riding, and sometimes back fires when reving at higher rpm. However it's not consistent...a few times it ran perfect...the only thing that has been consistent is that when near 1500 rpm or below it starts to starve for gas and dies out. I had put 2 cans of sea foam in 2 full tanks of gas and no difference wha so ever. there has been no mods to the bike...Im not that mechaniclly inclined so need all the advice i can get.
