I work on classic motorcycles for a living and use my dwell meter all the time on old Hondas and Brit bikes. It's really amazing how you can set the gap exactly, hook up the dwell meter and find out you're way off. Set the dwell, then set the timing on both sets of points. The difference between a bike that runs good and a bike that runs perfect.
These are a few of my past and current work projects, the Bonneville was my personal ride until my nephew laid it down and it slid under a guardrail. Managed to do some serious offroading with it after the accident but before insurance picked it up
