sounds like a CDI prob, my wifes 94 did that, swapped coils, stators, then bit the bullet and bought a cdi. Ran like a champ after that..... what year is your bike? maybe an HQ member near you will let you try theirs before you buy one, if you are anywhere near tulsa oklahoma let me know, id be happy to help... and PS, I have never seen a bad coil on a banshee. not that they dont exist, but you have better luck finding bigfoot than finding a coil thats actually bad..
