It's more accurate to use a degree wheel, but it will work. Like you said in the other thread, that's why it's making all it's power at 4 grand. Advance for low end. You could install it straight up with no problems, but it would probably take away some low end. Like I said give them a call and see what their justification is for the advance, it might make you feel better about it.

alright cool thanks. So instead of the horsepower being at 6000 rpm its gunna be lower. Does this mean mymotoris gunna tach out sooner and at what rpm you think? Cause I have heard with this cam it can reach 7000 rpms and still wants to go.

T5, if it's the same b-303 you mention in the "more power" thread, you should be o.k. The b-303 supposedly makes "lots of hp above 4000rpm". I believe that's because this is the point where it's making the best torque. I think you can still pull it above those rpm's to max hp without bogging down, that being acomplished with the heads, intake, headers and the stroke itself as torque doesn't fall to zero above 4000rpm.
