Anyone having trouble with there engine blowing after about 20 HRs? i have had this happen 3 times. the dealership could not figure it out so had the yamaha Tech come and rebuild it himself and break it in!! Guess what, it happened again!! it is blowing the 3rd Cyliner everytime.

I would suspect that somethings going on with the fuel injection system being that it always happens to the same cylinder...fuel pressure test ?...injector test ?
