Thanks Pete!
Not sure if I'm just lucky? - but I've ridden a few GRiSO's and mine just seems to pack a littler extra punch, and is silky smooth. The thing pulls strong and smooth from about 2k, and feels like afterburners kick in around 5.5k. I have about 14.5k miles on her, and so far no valve train issues ... Keeping my fingers crossed!
