1978 XLCH magneto conversion
I've been looking at my recently acquired 1978 XLCH and the ignition switch is worn, wiring is pretty ratty, and the battery is fit for nothing.
I do have a magneto available, and I was wondering what is involved to fit it? seems to be either a matter of finding an older cam cover and related cam gear, or an adapter fitting into the nosecone hole.
Anyone have any particular thoughts on this?

Go for an early cover...they make a tach drive setup tho I'm not sure if 78 still has the hole in the cover either way don't go that route I and another member have both had issues with them and we both went to the early cover and wish that we had just bought the early cover in the first place...

Ha ha, oh wow, I'm not even going to LOOK at all that shit.
Mag can go on the 45 as originally intended. Wiring is a pain but not expensive, I'll fit a plain clutch lever and wire horn and headlight flasher to the right-hand side pod. No indicators, the bike doesn't presently have them and a 1978 model doesnt need them in UK. No electric start, because the bike doesn't have one anyway. Batteries aren't cheap but they are just a thing you have to have.
Ok, press on.

I think ur bike came wit q grind cams (not sure wat year they started that)so your gonna want a set of early p or pb (p was stock)to run with the early cover but that's basically all that needs to be done to mount the mag
I think toward the end of the thread I posted he shows pics of the mounting a small bit needs to b ground from the mag adapter to clear the Vin block

Q cams didn't begin until 1980.
