If there's 1-2mm movement while turning the engine over, that's about normal for a cam chain in good condition. The problems can occur if you press on the end of the stem while tightening the bolt, which would exert more pressure on the tensioner than the spring would. Thanks, Chase

You can also have a whining noise from the cam chain being too tight, this will also cause premature wear and deterioration of the tensioner wheel and its axle.

Used carbide burr to re-do the holes, then had to have it rechromed. Also had the large late model DOT-type stampings o...
