Here's a problem I'm having on the BTSV and the Knuckle. The rear sprocket appears to be eccentric. adjust the chain at the tightest point to just enough slack, and it drags the brake rod at the loosest point. Doesn't make for the smoothest ride.
First, I replaced the worn rear sprocket, and , no change. Then, figuring I didn't get the sprocket riveted properly, I bought a new drum/sprocket ass'y from Ted's, same problem. Now, I didn't change the front sprocket as I'd done that a year ago, and it appeared to be in good shape. Anyway, the eccentricity appears to follow the rear sprocket, not the front. Also, a sprocket being a sprocket, I haven't figured how to put the dial indicator on it while the wheel ass'y is in the truing stand to get a better idea as to what gives. Anybody have any suggestions, or has seen this before? I figure it's something simple I'm just not seeing. All suggestions appreciated.
