Hello All,
Not sure if anyone has any knowledge or expirence with the 1970’s K&S Bike Machine motor that bolted on to the rear wheel of a bicycle. I used mine for about a year and now it does not want to run for me. It seems like it is not getting any spark. The points and condenser seem ok just wondering if something is wrong with the magneto. Also there is markings on motor that Kawasaki made parts of it.

Thanks so much

I have one, not run it for a couple years. Best friction drive motor, out board bearing and centrifugal clutch. Make sure the points are clean, and set at 20 thow

Just about every old Popular Mechanics mag. had a add in it..........Curt

Kawasaki? Huh, I had one briefly at one point, and it had a 31CC Mitsubishi engine. I guess they used different engines for different years. Anyways, points are common for pitting, even if it looks clean, a close inspection may show pitting. I had that happen on a Kawasaki KV75 I had. As far as Magneto, if nothing else, inspect it and the flywheel for rust. Points are much more likely to fail though than the magneto.
