Sorry about your luck. I was in the same boat. Diehard kawi owner (PWC. ATV, MX bikes). I have an extended warranty and it still didnt do me any good. My intake valves tried to play hide and seek in the heads and they (KAW) said it was due to dirt in the airbox not in the plenum but in the airbox. I said youve got to be kidding I dont ride in a clean room but there wasnt any arguing with them. Good luck arguing with them, I got tired of it and just went with a standard bore kit from FST and slowly getting it back together.
