I want to put a CDI ignition on my '74 TX500 but all that I can find are for XS650's. Are the points systems any different from each other?

I am looking at the Pamco Electronic Ignition Kit on http://www.mikesxs.net/mikesxs-electrical....category_id=2.1

Hi there the point plates on xs650 and tx were different but may fit you may want to browse the HPI web site you may find a better system. I have an HPI system on my FS1 it works fine !!!!

Right now I think I want to stick with the Pamco system BUT I will definitely take a look at the HPI site for consideration.

Thanks!

Emailing him now, Thanks!

Does anyone know the firing orientation of the TX500 engine? 360, 180? This is one of the questions Pete is asking me.

found it, 180 degree phased twin.

hmm, anyone know if the part the points cam mounts on is 8mm, similar to that of the xs650?

Pointless ignition is what im looking for too...keep us updated in your progress

ignition isn't pointless, its needed to ignite the fuel/air mix

Thats so corny...I could have said it...

too slow my friend, too slow!!

can we just get to the point?

So what did you end up using? and how did everything work out? - curious because I am looking to do the same. Just sent Pete an email, and waiting for a response.

Has anyone noticed that the XS650 ignition system is run off the end of the camshaft and the TX/XS 500 is run from a secondary shaft running off the crankshaft the logistical differences between the 2 are large. years ago the light sourced ignition systems (which sort of retained the points, less burn,) could interchange but modern CD!/TCI would have loads of problems .... Sorry Drewps for replying to your post but it was one of the shorter ones !

Nice find!

...Unfortunately Newtronic went out of business. I've been looking for an electronic ignition for my XS500 for about a year now and have had no luck.

anyone got any more info on this???

the xs650 kit won't work as that engine is a 360 crank, regardless of fitting problems it just won't work.

Newtronic are still going in one form or another, but I used to be a dealer for them, and I remember the number of warranty claims being so high I binned them. Terrible set up that just kept breaking down.

You should have a look for XS 250/400 and see if that can't be made to fit.
