Hey Smed, you are right the frame has just been redone.  It could be the problem, but I'm not so sure.  Obviously I will give it a try.  The photo doesn't show it very well, but someone has bogged up all the connections like the high tension lead to the coil.  It's a very dodgy job :o.
I will give Mr Honda a go and see what he has to say for himself  ;)
I can't be the only guy in the world with CR125 coil problems surely  ::)

Thanks for your help  8)

The ignitions are pretty bullet proof on those things. Just buy some second handies and be done with it. I might have a system you can try, to find your problem.

No worries Brad, I will do some measurements with the multimeter first to see if I can find the problem that way.  Apparently there is no such animal as an aftermarket coil for these jiggers.  I was dodgy on buying second hand as you never know how long these things will last and wether they are any good anyway.

I will have a look when I get home.  If all else fails there is always PVL - aussie dollar is pretty strong.

T - if you go PVL - check out Rex Caunt racing in the UK - can buy bits and pieces rather than whole units in the US - much cheaper?

cheers

Thanks for the Tip Rossco - I'll have a look at them.

Anyone got a Honda Manual that gives the resistance readings of coil, etc.  The Clymer one only has advice to check continuity - which is only a pretty basic go - no go test.

Unless the mounting is different to the picture that one is all wrong (for my bike anyway).  Appears to be the same as the black one I bought.

Mounting centres for mine are 80mm.

250H
Did you try the black coil? From the other thread comment was that coils can have a wide range of use.
The Dennis Kirk website lists a large number of bikes for this coil which supports this view.
The mounting points are different, it looks like the aftermarket item has only one mount, but it may still work.
Electrics are not my go, it's frustrating when you are trying to move forward on a project.

Haven't tried it AJ, but you do raise a good point.  It's probably good enough to get the bike going until I can find the right one.  Will also prove one way or another if it is the coil or not.

Sometimes you need to have the obvious pointed out to you ::).  I bought this one from MCS before having a good look at mine.  It said it was good for "early CR's"  Obviously not the prehistoric ones  ;D

If that fails I will buy PVL after Christmas expenses are out of the way  ;)

OK ..... Finally got some time to myself to play with this thing.  Fitted the new coil - although totally wrong mounting should be OK (for a test anyway)... Nothing >:(.  Next stop the stator.

I did measure the old coil and it was open circuit on the HT side, so.........

I have measured the following resistances at the connector near the airbox.
Black/Red to Red/White - 151 Ohms
Black/Red to Green - Open circuit
Red/White to Green - 136.5 Ohms

Can anyone verify these readings one way or another  :-\

BTW - Contacted Freaky's mate in SA.  HE has one, but it doesn't have 80mm mounting centres  :'(.

PVL is looking better all the time  ::)
