Thanks for the replies. I have seen the electronic ignition system from In motion, but it's says not for points system flywheels. I assume this means I need a different flywheel? Are these readily available? Thanks again for your help.

option 1. Buy a non-points OSSA flywheel and the In Motion ignition

option 2. Buy an ignition from somewhere else https://www.francetrialclassic.com/en/ignition/5010-ossa-250-350-electronic-ignition.html

I don't have a non-points MAR flywheel for sale at the moment.

Aren't there any OSSA specialist parts people in the UK? There are some in the US who would probably have what you want.

What's wrong with your points ignition?

I've never seen an MAR with points ignition to know what other bike shared the same stator setup. Maybe it's something common

I think they had points originally, I've got nothing on the ignition side of the crank so refitting an electronic ignition would make more sense. Thanks for the info.

Colin, my '74 MAR mk2 has electronic ignition standard, hence the question of others why they went to points in '75. Check out the Vape site, it looks like they can solve your problems, if not others will chime in.

All of the trials bikes had electronic up to the TR77 which went to points, then back to electronic on the Grippers. There are two types of electronic and the firing point pick-up is in a different location on each. On MK1 MAR and early MK2 the flywheel/stator have a small hole for the pin to set the timing at about 8 o'clock and the stator is a hexagonal shape, from about 1974/5 the later round type was fitted with the timing position at about 5 o'clock, so the flywheel and stator have to be the same type.  If you look at just a flywheel on its own, with the keyway at 12 o'clock you see the small hole for the pin in the flywheel face in the positions mentioned.

The electronic or points systems can be fitted to any of the MAR / TR77 / Gripper, the crank taper and stator fixing are the same on all, just the correct combination of flywheel/stator is needed

There was a flywheel on ebay a couple of days or so ago which I think was the later type although I noticed on In Motion they state the later type ignition is no longer available, not sure why as I thought it would be the same set up, just a different position for the pick up

You could try Martin Rickman as he has used MAR parts, you can find him on facebook under that name or this is his website

Or maybe Gary Warr who runs Ossa Stuff in the UK might have something, he races Phantoms but might have used MAR parts
