Good Afternoon Riders,
Well, I heard from the shop today, and they ruled out a bad CDI or bad
carburettors/fuel problems, and have narrowed it back to the stator
having a bad pickup somewhere that is causing my left cylinder to
misfire or be "out of timing". To those who recall, my uncle (with
minimal grunt work help from myself) put in a Rick's OEM stator. My
uncle being a mechanic, having worked on his own bikes in the past and
plenty of years dealing with electrical, saw nothing wrong when he
installed it. I am going to send the stator back to Rick's to have them test it to see if it is in fact faulty (unless anyone could point me towards how to test it personally, I know there have been posts about this in the past) for a potential replacement.
My reason for posting this bit of bad news is to get some kind of consensus on whether I should abandon hope and sell the bike or put the money and/or effort to solve this problem. I have already spent a pretty penny just to have my situation diagnosed, not to mention the other various parts I had to replace (front break cylinder, rear gaskets, tac cable, and probably the fork seals soon). I personnaly love the fell and design of the bike, however, I do not want to spend my entire riding season trying to fix it. Any thoughts opinions and concerns are welcome.
Thank you for your time,
Mike
EDIT: Rick's just called me back and said that the stator and the "pick up/trigger coil" is seperate from the stator that is sold. I will updated again when I learn more from the shop.

Without testing the bike with a good cdi then they can't guarantee that it does work correctly. I could send you one that they could test and I be it comes up in perfect working order but wont run your bike unless the cdi is 100% cold.

They did indeed check with a good CDI from a donor bike, it didn't make any difference. They told me that they are getting a low resistance of 7ohms (it should be 77 according to their copy of a service manual) reading on he blue and white leads which could POSSIBLY be one of the trigger coils...unfortunately the diagrams from Rick's are similar to something scribbled on the back of a napkin at a roadside diner.

I think that the engine in that other post is an 82, if it is, it or the stator from it, will not work in an 80.

I'm not real up on the CX's, but the parts fiche I looked at (to determine CDI or TI) did not list a CX500D in 82. The only non-turbo it listed was the "C" model, which showed the CDI. Or is there something else that makes the two incompatible?
This begs the question (for me, anyway): Could one take the entire rear cover, with everything attached, from a TI engine and (along with a few of the bolt-on's) convert the ignition types?

The 82 custom has all the bells and whistles of the gl500 naked. All previous cx500's are cdi. 82 is ti.

In that case Dillon Brothers' parts fiche has a small problem.
My most humble apologies. As the kid on The Stand said "I've been mislead".

I think they just get lazy in updating. The top right is Ti and the bottom right is CDI. They do this for tanks that swap years and a few other parts.
The Coils on the top 1 and 4 are cdi and the bottom 2 and 5 are TI.

The Blue and White leads are from the high-range and low-range ignition windings in the stator, not the pick-ups. The O/W and LB/W leads are from the pick-ups (perhaps they were referring to this?), but they are independent of the stator (though they are routed together from engine case to CDI.)
Also, the bike linked by pwtsvwt is an '81 Deluxe (there is a correction in the thread), so it would be compatible.

'Stitch,
I believe the '80 and '81 Customs have transversely mounted coils, as well. I have a set, with the clamp (#7), that are identical to my '78 coils, except that the HT leads are too short. I think maybe #3 and #6 are the TI coils, as they're shown with a different LT connector.

Well if anyone here has used and or knows about the Rick's stator, I spoke with the Rick's people and got the specs from what I should be getting for resistance in my triggers and the blue - white leads from the stator itself. They claim that the Blue to White should read 7 ohms, where on a factory stator it is between 77-90. Mine gets the 7 ohms. the set of leads for both triggers should have 200-230 ohms from lead to lead and 90-120 ohms from lead to ground: my stator is getting that.
And that is where me, and the technician at the shop, are stumped. Currently they are spending 1 hour to pop open the stator cover and check to see if anything is crossed or damaged or whatever. I probably could have done this myself but one hour isn't pushing it too far in my budget and the gentleman has 30 years under his belt. He claims his only concern is that 7 ohms on the blue - white, but Rick's assures me it is in spec. They have tried different CDI, boots, and sparks, still getting same result.

I've heard the claim that the Rick's stator has higher output than stock, so the difference in resistance is plausible.
Resisance checks will tell if the stator is bad, but not necessarily that it's good. Have they done output checks (both cold and hot) while cranking the engine?

Also, stator windings can have the proper resistance and yet be shorted to ground. The charging coils will not work when shorted to ground. The CDI coils probably do not also.
PS. The stator (charging only) in my bike shorts to ground after it gets heat soaked. I get around 30 miles before the volt meter read out starts dropping.

It was the difference in output between cold and hot that revealed my failed stator, too.

I will have to go over this with the technician tomorrow. Thankfully tomorrow I am taking a personal day from work to take the gramps to the neurologist and errands.
Thank You All as always,

Well they checked all resistances and such while cold and they cannot see any problems other than that 7ohm reading. They wanted to pop open the stator cover but then reconsidered as nothing will be visibly to them as far as the wiring goes (they thought some wires might be crossed.) I am picking it up tomorrow and plan to drop the engine personally and try to solve the situation, if not send the stator back to Rick's. I will keep in mind to check readings while running hot before I pull anything apart.
