This my sound weird but today I noticed a sound coming from the engine which I could swear is the cam chain spinning. Is this possible? Is it a bad thing? I never noticed it before and I am a little worried that it could be loose. I know the bike has an auto tensioner on the chain but I wonder why I can hear It now and not during the first 60 hrs. The bike still runs perfect so I am a little confused. Anyone have a similar experience or any possible insight.
