Chain Adjustment

could be associated with the fact that my back wheel and engine chain sproket aren't exactly in -line

I addressed this in a previous thread.

I think that I could have resolved the alignment with a "real" vise and a large crescent wrench.

Instead, as it was the last operation and horny to ride, I fired up the torch and bent the tension/idler about 7 degrees to be perpendicular with the rear axle.

Hope this will help,
