Looking for a little help with diagnosing a noise on my 2001 Kodiak 400 YFM. It sounds like a stack cam chain. I checked the Tensioner and it appeared to be ok, but fully extended when I removed it for inspection. I opened the cam cover and the tensioner arm (aft) seems ok, chain seems tight. I also noticed that the pull starter is very hard to pull. It seem like it might be turning over the starter as if it was still engaged. When it is started by the starter it makes a loud clang right before it starts. I read about the recoil clutch. Not sure if that might be the noise. The ATV is new to me. My neighbor has run it for the last year making the noise. Any help is greatly appreciated....Thanks..from tampa....
