let me begin by stating that i have come to this forum out of sheer desparation. i purchased my kfx in summer of 2007. love the bike. this summer i added a k&n airfilter, an ehs airbox cover and a trinity slip on. no problems. in november i took the bike to the dealership shop to get service on it, i was told that one service they would need to do was a valve adjustment. since that time the bike has been backfiring when i go off throttle. i wonder, what could be causing this problem? let me back up by adding that at the same time i purchased the slip on and filter i purchased a dyna tech efi module...i installed it, didnt know how to adjust it, and the bike would shut off, so i removed it.
dealership doesnt know squat about what to do and has hinted that this is my fault for adding the exhaust, airbox cover, and filter. they changed the plug today, and it looked like the bike is running lean (whitish-gray tip). i was told that the backfiring could be caused by the bike running lean.
i know nothing about the inner workings of efi, modules, mapping, etc. i assumed that an efi bike would make adjustments automatically for the slipon, cover and filter.
any help is appreciated. john
because when they told you to go get a green card you thought they said Green QUAD
