Is this common on the yamaha 660cc XTX? Yamaha said they wouldn't cover the repairs even though the bike is only one year from purchase, and in the warranty period, if this was due to over reving. Isn't a rev limiter supposed to stop over reving, with it's electronic cut out?

Is the bike standard? I wonder if it is modded will they not honour a warranty based on that? I would of thoughts a dropped valve would be covered within the warranty period as its a mechanical failure.

Maybe a more enlighted person will clear this up. I bet that will cost a pretty penny.
