How much radial play in front sprocket? (cb750k2)
« on: April 23, 2012, 12:33:16 PM »
My front chain sprocket (17T) has noticeable radial play. When i grab it and rotate it back and forth like a door handle, it rattles noticeably.
Is this normal?
(I'm not talking about LATERAL play -- in and out on the splined shaft--which is apparently normal.)
Seems like the sprocket should be a pretty tight fit radially on the spline to keep  from slamming back and forth with acceleration or braking.
