    took my 200 inline to shop,it had a miss i could not diagnose. the motor only has 5000 miles on a complete overhaul.iwas told there was a crack in the intake causing the miss,and that this was very common on this motor.they also said it would not be covered under warranty because it was a common problem with this motor since the head and intake are one piece.anyone familiar with this?

    Could the intake have gotten cracked from improper torque setting?
