I have a 2001 banshee new rebuild,.40 over stock ports, I'm using vitos super stock pistons, my carbs have been rebuilt, floats adjusted to book spec, I'm running stock carbs tors removed, I'm running lrd pipes with a toomey two to one air filter, 290 main with 25 pilots. My problem I'm having is, the thing only sparks on the third kick or so, and when its running its only out of one cylinder. There is smoke coming out of both pipes but more on one side than other, the only way it sorta runs like a banshee is wide open. I tried a new coil and it did the same thing, would only spark every few kicks. You can feel when it sparks because it chugs forward. Any help would be appreciated! Thanks Dustin
