I have a 99' yz400f . The bike has a fresh top end but the other day I fired it up and it started making a loud ticking sound . I took it to a couple of local shops and they thought it might be the cam chain slapping or the counter balance bearing but they were not 100% sure.I checked the crank for slop but it s fine.Any info would be appreciated.
