    I recently completed a partial triple bypass on my 1980 Honda CX500c (engine out, front and rear covers off, replaced all seals, chains, springs and tensioner guide/blade). I also did a carb clean and rebuild since I was taking things off the bike. I got the engine and carbs back on the frame...

    Story time! Decided to do something about the mechanical seal on my bike. Dropped the engine, opened her up, extracted the old seals... Couldn't find a replacement rear cover gasket. Bad timing, I suppose. Not to be discouraged, I decided to check a few other things while waiting for a...

    Hello everyone, new to the forum and a new owner of a 1980 cx500. Got this bike for really cheap a few days ago and the only issue it had when I did a walk through was that it was running only with the choke and would rev so high when I take the choke off. This lead me to believe that it was...

    Okay, incredibly intelligent friends, I have an electrical riddle for you. Need some ignition help. We put a new wiring harness on our GL 500. Wired up the ignition circuit and hit the starter button and the starter turned over, so we called it a day. The next chance we had to work on the bike...

    I've started to replace my existing (partial) Rae-san kit with a new full Rae-san kit including hall effects sensors and rotor. However, when I removed the cover plate I found a mystery wire has been bolted to one of the fixing holes. I'm assuming this is a ground wire of sorts, but it's not...

    Hi All, I know this may not be the right place to ask for help with the m units specifically, but given the wealth of knowledge here I figure there's someone here with an answer. I bought someone else's CX500c project bike that I got up and running this week(!) thanks to a lot of help from...

    I just got a 1982 GL500 for 600. Already half way built into the cafe that I envisioned. I’m fairly savvy in electrical and mechanical as I am a technician. The guy before me got the bike and never finished it. He did some kind of janky wiring work with the ignition system. I’m attempting to get...

    Installed an ignitech DCCDIP2 ignition on my '79 cx500 to overpass the bad coil in the stator. After I've installed it, the bike will run and shift into gear, but has no power at all to actually get the bike moving. Checked all the wiring and it seems good/right. Feels exactly like gears 2-5 did...

    Let me start by saying I have done some looking around beforehand and as far as I know I do not have a 80+ ignition (previous owner says it used to work just fine before it got torn down) My current issue is that every time I turn the key to Park it blows the main fuse. I have tried unplugging...

    Hey guys, I have a 79 cx500 that used to work just fine(except for some wiring connectivity issues to the gauges). One day I started it while it was leaned on the kickstand. It seemed perfectly normal. When I sat on it and kicked the kickstand up, the engine died. Now it will only crank but...

    I bought a non running cx500 guy told me it needed battery and spark plug and so I bought a battery and installed it and the bike had no power to it (I checked the battery and its good) anyone know what else it could be?

    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 ?

    Hi all, So, today I was an idiot and probably fried my Ignitech unit. My ignition switch had been giving me trouble for the last week or so, where the bike would shut off and then turn back on again with a jiggle of the key. Today on my ride to work it was especially bad, dying completely just...

    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...

    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...

    Hi guys, As some of you may know I had an issue a while back with my cx500 intermittently dying whilst running at higher rpm, this was put down to a dodgy stator. First thing I did was replace the CDI with an Ignitech unit, which means there were a variety of stators at my disposal now... I...

    I know the Yamaha YFM80 coils can be used to replace the originals on my CX500, but I've recently seen a listing for 2 others I hadn't seen before. One is listed for a CX500 and is part no IMC0009. The spacing looks correct, and it's twice the price of the Yamaha ones. But not having to add...

    Hi everyone, My 78 CX500 I just picked up as a project had no key switch. I went ahead and purchased this Emgo, 6 pin switch and I need help with the wiring. Any help would be appreciated with finding out what pins go where. Thanks
