Roughness Off Idle - Continued from Electrical Thread

[Suzuki_Don]

I might try and modify the 650 advance unit that I have. It is about a 1/4" longer than the 550 unit currently on the bike. Or I could file the stops on the 550 unit so the bob weights can advance a bit further at higher rpm. And then check with timing light at full advance after marking the 40 deg mark on the timing plate (on advancer).

Pete, unfortunately the bob weights will not swap over. Good suggestion though.

That's a pity Don, but I guess it would be too easy right?

I guess the other (expensive) alternative would be a programmable ignition...
