with your sidecar or trailer did you keep your stock gearing.i did change my front sproket 25th to a 24thcan i do the 23th witout changing for a shorter chain.

I run stock gearing in the final drive and installed a Primo belt drive in the primary. The standard electric start Primo set-up.

I haven't changed yet, but would sure like to drop a tooth in the front. With the sidecar on mine lugs to much on take off, and it seems a 500 RPM increase would help a lot. 6th gear is pretty useless.
