Second...like it was said, 87 octane is just fine for R*, but higher octane should not caused what you described.
Third...the dealer should have given you more info, instead of "don't use high octane". I hope the dealer doesn't know something that they didn't tell you.
Lastly...You bought the best of the best. I have the sme bike (mine is an '05 though)
Good luck. This is the greatest site for Roadies!!!
