If it is a race bike, do it. You will pick up 1-3 or 4 hp if you are lucky. You won't even feel it on the street. And if you are going to bother degreeing the cams then adjust the valves ACCURATELY to get that last 1 hp.
Ernie, the bike will end up on the track as soon as I get a 07 and plan on the valve adjust at the same time. I pm'd you today about the adhesive for the new short air horns on the air box. What did you use? Can't find the stuff listed in the service manual. Good to know that it nets that many hp.
