Shouldn't matter whether the bike is still under warranty or not.

Your problem first originated whilst the bike was covered , so the dealer is under obligation to sort out an existing problem!

I agree with mikesps in that it is probably a problem with the adjustment on the operating rod!
I had a similar problem on a CBR i used to own where rear brake wouldn't release fully when warm!
Solution........Adjusted the pedal up slightly to increase play!

Not the same bike, i know, but arn't all systems similar?
