ok I purchased an 03 banshee with pipes, reeds, boost bottle, and kn oval. Its jetted. I had problems with it not going over 3000rpms when I got it. I ruled out TORS, Coil, electrical, compression, anyway it ended up being the precleaner on my kn was clogged. I fixed it. I took the banshee out yesterday and it took about 10 kicks a little messing with the choke but it started. It ran great for the 2 hours we rode. pulled very hard and I was very happy. It started to downpour so we rode out and trailered the quads. Today I took it out to clean it and tune it up. I kicked and kicked without even a putter. Then I changed out the plugs and tried again, this time I finally got it to start. It ran for 10 seconds and died and wouldnt restart. I decided to check the filter again. I cleaned and re-oiled it and tried again. I kicked forever but it finally started for 10 more seconds and then puttered out. I touched the pipes and the right hand pipe was very hot to the touch and the left was ice cold. I tried to start it again and nothing. I run 32:1 premium with yamalube R.
Im about ready to give up on it, Ive ridden it once in the 3 months Ive had it. The rest of the time Im figuring out these gremlins.
It ran fine in the rain all the way til it was loaded up.
