TM250 stator plate diameter

[cyclegod]

Can someone who has one please tell me the outside diameter of a TM250 stator plate.

120mm OD

120mm OD

Cool, looks like TM250 stator and rotor are the go, just checked and found that TS250L and TS185L use the same external rotor and stator plate, along with primary and pulser coil, just different charge and lighting coils

Dont mean to hijack this QUALITY thread.........

What is the easiest way to convert my humble little TS125 from points to PEI / CDI ignition, I want to do this to eliminate moving parts and the associated wear, plus the reliability of the pointless system.

I still need charging and lighting capability.....

What will fit with minimal ease?

TS185?
TS250?
Anything else ?

I can turn down the stator plate to suit etc.....

I want something SIMPLE to start with to get the bike running reliably and then go from there......

[DR]

you may do well to look at the TS125ER ignition. They'ed be the closest as TS250/185 are much bigger. TS100ER stator plate is to small from memory. Never really done this swap as I've never needed lights and simply bolted on the TM125 ignition.

Good point Doc. I'll have a hunt around for a complete setup, must be one somewhere.... Got any pics to get me started os specs?

[DR]

no not really..nothing at all ..I have doood a little scheming (micro-fishing or whatever you wanna call it) it appears the TS100 and the TS125ER use the same stator the thlot plickens so now I will try my TS100ER ignition on a TS125K bottom end and report back with the resulting results, maybe a few pictures if there's anything worth a thousand words or more

This is what you really want.


Reality is ANY stator/rotor combo that fires top of every stroke, and has 12V output will suit your needs, to a large degree.

ooohhh aaaahhhh,thats very nice!!, Lozza whats it's application???,2 smoke twin with lighting?,or

[DR]

after some physical rooting around and visual comparisons I'd say the TS100/125ER ignition is a straight bolt on affair for the early TS125. The stator plate is all but the same and the mag has the same TDC keyway and taper for the early crank..all good

Im with Doc, go for the TS125ER ignition or if you have dollars then look into what Lozza has or those ones i told you about a few weeks ago.

[cyclegod]

I don't think an ER stator will fit it has a 3 hole stator plate for starters...

[LWC82PE]

my reply was for ss2fly

doesnt matter if its 2 or 3 holes. you can drill new ones where ever they are needed to be.

[ss2fly]

LWC82PE, I had a good look at the stuff you told me about the other week, all good gear, although I think that type of setup is a way off yet....

Doc, drilling new holes is obviously no issue, except for getting the stator plate positioned right to get the timing right. How does one do this correctly?

This sounds like the setup Im after at this stage, what years of TS125ER am I looking for ??

[Lozza]

Never you mind Mick, you leave all this high-tech star wars stuff to me and stick to mixing up epoxy Taper is for a Yamaha Banshee/RZ/LC but can be made to go on anything, the pictured stator plate is for 1,2 or 4 cylinders and another plate for 3 or 6() cylinders if you dare.115w 12v output.Can be set to twins can be set to 180 or 90 deg firing or proper screamer even 90 deg for a 4 cylinder, now that's a noise.Could probably even run on a cough, spit 4 banger with a waisted spark on whichever of the other 2 strokes it wastes
