My banshee isn't as fast as it used to be and I have no idea why? It used to be able to do wheelies with ease in third gear now I cant even do them. my bike back fires a little bit throughout the power band. I haven't done any major changes that would cause it to lose so much power. I assumed that it might have been an electrical problem since it was backfiring and already inspected the jets and carbs. I switched the coil, cdi, stator with a friend of mine and it didn't help. My bike now is slightly slower than a banshee with pipes and dual clamp ons, but faster than a stock banshee. Any help would be appreciated so I can have more fun by this presidents day at dumont
