This may seem strange, but I put on a new x-ring chain on my 04 YZ450F and now it is making a horrible noise up front by the counter sprocket. It didn't do it before with my worn out stock chain. I still have the case saver (chain guide) and front chain guard cover. It only does it when the bike is under power, but doesn't do it when it is coasting. I am very puzzled and afraid to ride it because of the noise. We are heading out tomorrow for a weekend trip and doing know what to do. Any help would be appreciated.
