After talking with Mike and Mark at AHP..... I have no doubt that they will take care of the problem I have been having with my motor. Mike at Trailbikes offers a generous amount of support that can't be beat. We have an "idea" of what my problem could be but won't know until further inspection. If/when I find out.... you guys will know too. I do know that only a very small amount of the kits have had a problem. It happens when things are mass produced. Any and all problems will be addressed asap. TB has built a reputation that speaks for itself and it's hard to overlook that. Anyway, I said I'd update so this is where we stand. My head is on it's way back to Mike. He will find the cause of the bent valves and let me know. In the end, I will probably just miss out of riding time with the stretch of nice weather we have coming up. It sucks but I WILL be riding soon.
