well guys i brought the head down to school with me 2 weeks ago. I pulled the springs out, did some porting w/ the angle die, and put in a new exhaust valve, as the old one was mushroomed out on top. I put the cam in this past weekend and it makes a world of diffference. The cam is a duncan racing .450 lift billet, w/ that i put in a set of r/d springs. I didnt get a chance to ride but about 2 hours although I did open it up a little after about an hour of break in and it pulls quite well on the top end now, revs higher and has more of a mellow tone. Hopefully there will still be some warm days left to ride b4 it gets cold all of the time.
