I also have a ? about graves cam. I have Graves Full TIT system ,ram air box,velocity stacks,pc3 and pushing 146hp. By the way it's a 02 r1 w/about 15k mi. I'm thinking about doing head wk and installing grsves intake cam. Will I be satisfied w/ the hp gain. Does anyone have any suggestion on what to do. I have $2,000 to spend and I want more power. Feel free to email me.
