Can anyone tell me if the CDI box, and magneto complete from an RM125N/T fits an RM125B/C? Is there any later models that fit onto an RM125B?
Has anyone fitted an aftermarket ignition to the RM/B?

Late model DC/DC ignitions are vastly superior to old high voltage ignitions, can be adapted ignition by machining a sleeve for the crank taper. Late model CR 250 is a good one to adapt. With the cheap LiPo batteries($86 delivered) that weigh less than the box they come in and can run at any orientation, running total loss the new fully programmable ignitions are hard to go past.

Just fitted the ignition off an RM 250 N ( i dont have an RM 125N set up ) to an RM 125B and it physicly fits . Will try to run it later and report on Timing / performance .

Bill,
My bike ran perfectly for two races then gave all indications that a plug had failed. Replaced that but still the same it just misses then dies under load. Runs for a little while when started from cool.
It looks like a CDI unit but they are all approaching 40y.o. so even a good one is questionable. I am not sure that spending money on the xisting one is worthwhile. Was just drawing on the brain trust here to see if a 1995-200? one fits on.
I may look at a new type system but a lot of money.

It probably failed cause your arse is too big for the seat. You are not still seventeen Gregory :o
Year 2000 electrics permissible on a Pre 78 but not 1976 swingarms ..I smell a rat ::)

Well the 2000 electrics actually existed Ted while the phantom optional alloy swingarm is just a myth printed in the parts manual as joke by an unhappy worker at Suzuki in 1976 ;D
Greg H I would rather push my two stroke while making ring ding sounds than consider buying the parts required to do a basic top end freshen up on a bloody 4 stroke ever again. I mean the gasket kit alone requires a box trailer to bring home with more gaskets, 'O' rings etc than in the space shuttle. The other thing is the power ::) ::) or more exactly the total absence there of. The little 2 st with me making the ring ding sounds still roosts those 2V XR200 ::) :P :P :P :P ;D ;D ;D ;D ;D ;D ;D ;D ;D

Oh yeh you two (Ted & xl59) great that you contributed but umm how do I say this umm Oh yes PISS OFF with your Tom foolery this is serious :P ;D ;D ;D

Always a pleasure to be of assistance. Feel free to burden me with your woes anytime ;D
Here's a thought , Why don't you port the shit out of it with those specs I SO KINDLY gave you and if you ever get it running ( you know, within the spirit of the era, of course ) it will go like a scalded cat. Something to ponder. Have a nice day

Spent most the day sorting my Rm 125 T ignition wooes so I thought I would
post my out come.
Bought this bike about 12months ago, the previous owner said you had to push start it to make it run ???
Any way I decided this bike was in need of a total rebuild and I would have the stators rewound / buy a new coil and I had a spare CDi unit so I thought I had it covered, 12 months on
So today all I needed to do was put fuel in it give her a few kicks and away we go ......Wrong ::)
Ok we have spark and fuel kick kick and many more kicks .... no luck
replace coil .... no not that ..... replace carb - no luck either ... Replace cdi - still no luck ...
I don't have a spare Rm 125 T stator to try ..... but I have spark and it has been rewound, So I assumed it is ok
Ok push it and it starts ... Wtf but it won't rev.
Time for a cuppa as I'm now at wits end to what it can be ?????
Remember this bike has had many owners so anthing is possible....
So I pull the mag cover off my Rm 125 B and notice the coils are in different positions .. Ie small on top and large on bottom , where as mine are the other way round.
Time out to look at tech books and another cuppa .... yep swap them around
around.
Kick kick ring ding ding ding give it a bit of thottle riiiiinnnng ding ding ....... you ripper.
Conclusion.... at some stage someone has had the coils re- wound and forgotten which order they come out

Fiddled with my 'B' ignition today. Checked all connections and cables for continuity all OK, checked all earths and mounting screws all clean and good continuity. Installed the CDI off a T model but still no go.
The bike came with a MotoTek ignition module so put that on temporarily and started straight up and ran normally. This proved the stator. I am now suspecting the HT coil. I used a generic coil designed for CDIs from the local bike shop. It tests OK with a multimeter but I don't really have any reference values.

Have ordered one of these so see how the quality is
