I found a Maxi-Dwell

Administrator

I found this when I started to tear apart the engine, for my Buddies POW/MIA bike. I have heard of Maxi-dwell, but do not know anything about them.

Yea it's aftermarket. I don't know anything about it either. It does not use condensers, and has a little 3 position switch on it.

Interesting. I'd be curious to see how this works. Anything on the other side, like how it's changing the dwell?

The use GM points, like those on the old vette. At least they used to which is probably why no condenser is needed, these are a lot more robust than our stock points.

The ride IS the adventure. The destination is just to get gas!
