gtyr head cams come with it, yosh or fmf Yamaha map, 14-1 piston u4 fuel instant rocket ship, had crower cams the Yamaha gtyrs are better. The cams and piston are the biggest gains,had them before the ported head,added the gtyr head better but not crazy better.The map is on Yamaha web site in the tuner area .Still going to push in turns, but gone down the straights.
