I recently bought a 1981 CX500 for super cheap and the guy I bought it off of told me it had a bad pulser coil but that it wasn't a big deal. I got it home and did some diagnosing to figure out what all was bad and found that I had no spark to my left cylinder and a weak spark to the right...

Hi, I joined this forum to learn about the ignitech system, I know Cobram is the guy to speak to but i'm not sure how to get in touch with him. Also is Ignitech the name of the system (More than one company makes them) or is it more like the name of the company that makes them? Thanks in advance!

Hi all, long and short of it is why do the TI ignition cx500's (or gl500's) have 45 degrees for ignition advance over the 37 of the CDI bikes?. The only information i have seen is that Raesan advanced the timing on a eurosport somewhere to 42 degrees but nothing else. I have a 1980 deluxe with...

I got a pair of these because they seem recommended but they measure at like 3 ohms on the secondary windings where the stock ones measure 7.5. My stock coils are still working it seems. But my CDI seems to have failed. I have a replacement coming this week. Less impedance on the secondary...

I've recently tested my stator using the guide on this forum and found that my stator and left pickup (trigger coil internally) need to be replaced. I'm looking to go with the most simple upgrade path that will modernize the entire system. The bike in question is a 1979 CX500 Custom (CDI) that...

Struggling to find a new CDI for my 79’ CX500 Custom. I’ve seen in post from years ago about “Cobram“ doing bulk ingitech orders and was unsure if that was still happening. I’m in Vermont and would love to get a hold of one in the US if possible, but will bite the bullet if needed and order...

Quick background explanation... New to me 78' CX500 with (I think) 80' CX500 engine. The left cylinder was not firing when I bought it. Have replaced: spark plugs, plug caps, cleaned carbs, and jetted down to 78/115 from 90/120 (running pods), new pilot screws backed 2 turns out. The bike now...

So my ignitech is toast so where do I get a new one. PO had it installed

I wonder whether someone has ever checked the ignition timing ( CX500 C, CDI) with aid of a stoboscope lamp ? Would you need such a cap on the inspection opening or would it work without ? Would it be an oily mess without the cap ?

1979 CX500. My current situation is that I have recently purchased an OEM CDI on eBay, not knowing the high(blue) and low(white) coils were burned out from the previous owner replacing the original CDI with the ignitech(older version). So now I have an OEM and ignitech(older)CDI. The OEM doesnt...

New to the forum so not sure the exact protocol on asking questions. Bought my first motorcycle, '81 CX500D, about three months ago. Ran great, for the first 6 rides except that it would cut off every once in awhile when idling at a light. Took the bike for a sunset ride and filled up the...

Looking for just one CDI unit for my CX 650 Eurosport....(still runs on one cyclinder to begin with so starting to replace bit by bit to eliminate problem) PS suggestions on fixing this issue welcome ///done the HT leads, the spark plugs (iridiums), the coils etc....plug caps....just going bit...

Hi all. So my 1979 CX500 stator has continuity to ground, so seems like I need a replacement. First things first - it's a CDI model so am I right in thinking that its the G47 stator that I need? I found a site in the UK (where I am) that makes them but they seem to describe it as fitting the...

First off, glad I can be a member of this cx community to take advantage of all your knowledge. I have read tons of threads about stators, CDI, pulsars, etc. Perhaps so many I've got myself mixed up. I know some threads show the ignition system test results, talk about Ignitech, etc. I just...

Hey guys, I've got a 1980 CX500 with the ignitech cdi that I've been trying to get running. I had spark but it randomly went out on both sides the other day. I've done the multi-meter tests the for the stator and pulsers and they were all within the acceptable ranges (sheet with the...

Hey everyone, I'm new to the forum and actually came across it in my search for a new CDI module for my 81 CX500c. My left spark plug isn't firing and after tracing it back past the ignition coils, cleaning up all the leads and checking my wires, I've come to the conclusion that it's most...

Was out for a long ride on Saturday, bike started to cough and spit then would not run above 4000 rpm. Limped home 20 miles. Swapped out the Ignitec from my other bike and it ran fine. Now need to source another Ignitech Before riding season is over. Does anyone have one for sale? When is...

Hello, I just picked up a 1980 CX500 and the left coil wont spark. The right side sparks when it is wired normally. When I swap the pink and yellow cables, the left side still doesnt spark. Which leads me to believe that its just the ignition coil. However, These are brand new. I checked the...

I am selling this CDI unit from my 1979 CX500, to give some background the bike was running (not well) when this part was taken off I discovered that the pickups for the stator and possibly the stator itself was bad. I believe this part is functioning as it should be but it is 38 years old...

Hi All, I've been working the last year on rebuilding a '79 custom I bought from a barn. At this point almost everything is done, however I wont be able to get the bike certified as it wont turn off when I turn off the key. The kill switch works great, but I took it apart just to be sure, and...
