Same cam, just needs the bushings added for the points camshaft.

I don't really know why anyone would want to.

easy and cheaper to keep running with points. specially on the side of the road.

There's no doubting simple and reliable are very good traits in most things. I have done road side repairs myself in the past.

You might change your mind when you find out that the new (but Chinese) points and condenser you are carrying around and try to use are useless because they're junk. After having dead on arrival points and condenser I looked at buying genuine Yamaha spares but they cost around 2/3 the price of a complete Boyer Bransden ignition kit. So I bought the BB kit.

IMO, the quality of aftermarket ignition components like points and condensers is at an all time low.

I have read here on the forum that the cams post 1980 are not machined in the seat for the Bushing
No need do it on the factory
So when smashing it in ( Bushing ) the cam can crack In some cases.
I believe it can work Unknown if any grinding or so has taken place.

to mike in idaho, thanx man, I also have a collection. 8 650s, a dozen brit bikes.
maybe 45 -50 bikes. as for cracking Cam, Good to know. I'll be carful.

TCI is the electronic ignition that came stock on the US models from '80 to '83. CDI is a different animal.

I was known in school for running my fingernails over the chalk boards.
