Thanks for the update Ken. Been thinking about the 865 kit myself someday. Sounds like you had the bike on a dyno to test the A/F ratio? Be interested to hear your final setup. Also, did Triumph performance work with your shop to get you the parts and exchange the cam core? I wondered how they handled that logistically, since I know they want the stock cam returned after the 813 cams are installed. Roughly how much did your shop charge to put in the pistons and cam?
