Cam chain replacement, checking for bent valves.

With less than 20 hrs on my last cam chain replacement. I broke another one this past weekend. I am thinking that it was my "at home" chain rivet job quality.

Now I need to check the valves to see if they are bent. I am thinking of just rotating the cam and checking the valve clearance. I had just adjusted them before my ride. So I have an idea of the clearance. Would this method work? Or do I need to remove the head?

I am thinking of getting a cam chain rivet tool. Does everyone use a tool? Which tool do you all use?

Oh and lastly which cam chain are you running. My last one I think was a OEM replacement.

Hair, with the rocker cover removed you should be able to do a compression test, poor compression then very likely a bent valve. Now your next question will be what should the compression be.......... not sure with the cover off but with it on it should be around 130psi.

Hope this helps,

go to a split link. 100% reliable, except that when things go wrong it gets the blame when it's not it's fault...
