I have an 01YZ426 and the cam chain movement is definitely audible. Is this normal? I am going to check the valve clearance soon so is there any specific inspection tips to look for cam chain wear etc.?

Mine does the same. Mine did it before and after adjusting valves. Not sure how to get rid of it. Anyone know?

make sure your cam chain tensioner is working properly.

I recently replaced my cam chain.....My tensioner was fine..now I know theres a new one in there...Gives me peace of mind..If you buy a used 4 stroke, and the owner doesnt have any documentation on its replacement..Replace it..Cam chain failure is a bad thing..

Did you replace with the Yamaha replacment or an aftermarket one?

Thanks for the advice. definitely makes sense in my book so I will certainly spend the $30 for a new OEM cam chain.
