Anybody got a MK3 CDI unit they want to sell, or a known good one I could loan to prove beyond doubt that the one on a bike I am working on is fried, I am 99% certain it is, especially since its a known weak point, but the customer isn't convinced (odd stance but there you go)
Alternatively, does anybody know of a good alternative, I know I can get an ignitech unit and fit that, but just wondered if there was other options as 125's aren't my thing !
Thanks in advance

Dave - what are the symptoms ? i went through this on my Mk3 YPVS and it actually turned out to be really slow because of
1 - my extra weight since i last rode it.
2 - air gap on the pickup was huge.
If you don't source one i will lend you mine to try

yeah, it starts ok, but after a few minutes, it coughs, splutters and then stops, won't restart for a good while, check no spark, then it statrts, then same again after a few minutes, its not the stator or low/high side coils etc, they are all fine, both cold and hot, pickup is also fine
Everything else checks out, its the only part I can't test and does smell of CDI issues like the 31K when that starts going, very similar symptoms

Dave . the one off the first tzr125, 2rh does the job. dont bother putting another 1gm cdi on it as they are cac.
Someome is also making new ones but cost a couple of hundred quid. a used tzr one should be less than 50 bucks and dont give trouble.
