I did not mention regulator/rectifier. They normally never go out.

The oil soak that the domi uses for it's stator is not healthy to stators. The insulation comes off and makes it useless.

If it was the regulator/rectifier then he would be blowinglights and genrally not be intermittent. It would be a black or white issue.

Apart from obvious (like all wires are connected) then I'll stick with the stator .

Even though the domi/XR650L have entire diff electrical systems, the oil bath destroys stators.

XR600 riders on long trips know to carry a spare stator as replacement.

Anyway the real test is to swap one out. Inspect it and see if thw wires are going.
Except that practically ALL the Honda singles have seperate charging and ignition systems.So it WILL run perfectly happily without a battery,regulator or charging coils...i've just tried it on my mate's Domi('89 model with kichstart).The entire systm is comprised of small generator coil,pulse coil,CDI box and HT coil/lead/plug cap.Everything else in the system can be disconnected to isolate any suspect sidestand/cutout/ignition switches,etc...I previously mentioned the intake rubber as my mate's Domi has suffered from this a few weeks ago and it caused irregular running/cutting out,and wierd/horrible noises(pinking mostly).They usually split on the underside where you can't easily see of course!

umm who said anythign about a battery/regulator?

I'm talking about the stator which is buried inside the left hand side engine case. It generates the electricity to start the bike and keep the bike running.

No stator generally means no engine

Again I am not referring to the regulator/rectifier which have NO bearing on the spark or ignition.

The cutting is caused by the stator wires unravelling.

rmhrc628 - you and I have different experiences! CDIs can get very hot when failing. mine got so hot that the solder evaporated inside it. I'd also be surprised if the Dommie was immune to reg/rec failure and reg/rec failure can lead to CDI failure and loss of power/loss of ignition depending which circuits burn out.
having said all that gloomy stuff, I hope its not the CDI & reg/rec as they can be expensive!

Granted this may be the case on an XR.....but the original topic refers to a Dominator which is what i'm talking about.Dominators/XL600s have a different stator to XRs, and don't have any issues regarding reliability of said component.The items i reccomended to be checked ARE an issue with Dominators.

If anyone has suspect electrical problems try www.electrexworld.co.uk as they do aftermarket generators/stators/regulators/rectifiers,etc...They can also test your part if you suspect it's got the gremlins.

Red face *blush*
Thanks to everyone for suggestions. However, nobody seems to have grasped the true depth of my incompetence.
It turns out there were two problems:
1: Misfring (eventually cured by coil swap).
2: Bad mech. noises (eventually cured by me taking out the oil filter and putting it back in the right way round. In my defence all the other filters I've fitted have some sort of indication as to which way round they go. This one didn't.)

Thanks again everyone...
