!970 Rupp Scramber...10" wheels
What would cause a slight wobble in the sprocket that causes the chain to loosen and tighten as it rotates. Used a marker, laying on the swingarm and rotated the wheel, and got about a 6" line (it got closer to the swingarm) on the sprocket. I can see the slightest of wobbles but I had no idea it needed to be so true.
Plus how the chain gets tight and then loose, and then tight again as it rotates is causing me a brain fart.
Thought maybe a bent rim so I swapped the front and the rear and it does the same thing.
Bent sprocket? It seemed to lay flat when I had it off. Thoughts?
Thank you
