Help Please!!!
I cannot get a spark on my 85. At the moment there is a 2mm gap between rotor magnet and pickup coil-somethings wrong i think!
Problem is i cannot find what number stator and magnet go together. I can find part numbers ok for what an 85 should have but this doesnt help much because naturally they dont match the actual numbers on the items.
The current setup on my bike is:
stator plate with M81975D stamped on it
magnet with FP8153 stamped on it
Has anyone got an 85 500 that they could read off the stamped numbers please as i dont think that plate/magnet combo ive got is a match!
Thanks John

I played with a bunch of 85 ignition stuff and I think the real problem with these is that all the connectors are aluminum making it really hard to get everything working consistently.
I gave up and am running a 92-6 ignition.

Yep, definitely not the best connectors wise but the main problem ive got is that im not sure that the magnet and stator are matched because ive got a huge gap between the magnet and the pickup coil.

I fought off the garage monkies and somehow located my 85 stuff in a junk pile. It has the same numbers and gap as the stuff you have.

Thanks for looking at your 85 stuff to compare the numbers etc, much appreciated!

we had a 85 that was also a pig to start so much so you would kick the soles out of your boot i wish i had of kept it and put the 250 ignition in it its would have been a completely different beast

I've been offered an '89 250 cdi and stator but no flywheel magnet, which, if i can get the correct magnet, would hopefully enable me to junk the 85 stuff and get the bike to actually work.
Will a flywheel magnet HAVE to be a 89-92 250 to work with the 89 250 stator? or are all the 80s-90s 250 magnets the same?
