Burnt Valve?

[Type R 702]

Has anybody had this problem i have a 2000 itr supercharged and recently i burnt my exhuast valve somehow i dont know how but i need some helpful information on this case such as what caused it and what to do because dealer wont cover this under warranty

Do they know it was from a SC?? If so, how?

I've been *thinking* about moding my '01 ITR, and have wondered if and how a dealer can point blame like this.

The air fuel mixture on a stock, or mildly modded ITR can't be off far enough to burn a valve. If the mixture with the supercharger is off just a little, especially on high speed runs, things can get awfully toasty.
