Anybody have any advice on changing the cam chain, Tips, Tricks etc. I am leary of the one on my bike as the cam chain tensioner was trashed when I bought it, it was as far out as it would go and was still noisy so I am betting it is at is limits so I figure I would be better off spending the money on a new chain since I dont have bent valves etc from what I can tell when I did the valve adjustment. any help advice on this would be great.
