Finally got my 450 Ex. cam today woohoo. Prolly take a couple days to install since I dont have long to work on the bike before the yamaha shop closes where I can pick up the shims. Does anyone have any secrets or problems that I might run in to? This will be my first time in a big 4 stroke motor so I'm sure anything can help. I have already printed off alot of info that I think I will need.
