  2. CX500 Ignition timing check

    Technical Help Forum
    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 ?
  3. Ignition switch/Ignitech troubles

    Technical Help Forum
    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...

  7. Have I bought the wrong stator?

    Technical Help Forum
    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...
  8. Coil ?s

    Technical Help Forum
    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...

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...
  12. Suspected Carb Issue? - Diagnosis Help

    Technical Help Forum
    G'day all, first time post. Understanding that this topic is well covered, I have managed to (as a new rider/mechanic in general) narrow down the symptoms which have niggled away at me since I bought the bike a month ago. So, I've reached a point where the issue seems to be only the left carb...

    Where Can I Find...
    Hey everyone, I have recently had my stator go out on my 80 cx500c and when I went in to change it out I noticed the wires on the stator weren't the same. From the research I have done I have come to find that I need to update my ignition system from the original CDI. I found the part at...

  18. 82 CX500C no spark

    Technical Help Forum
    My 1982 CX500C was working fine for the last few days, but it suddenly stopped working. I tried everything I could think of and finally, with the help of my dad, found out it had no spark by pressing the spark plug to ground and cranking. There is no spark and I don't know why. I'm hearing a lot...
  19. New to electronic ignition, bogging issues.

    Technical Help Forum
    Hey everybody, first post. Searched the forum for some answers, found some good material but my bike seemed to "pass" the electrical tests. For reference, I primarily work on BMW Airheads. I'm used to points, carb tuning, air cooled, etc. I picked up the CX500 because a friend asked me to help...
  20. More ignition switch problems, any ideas?

    Technical Help Forum
    So I finally found a new ignition switch and it seems to be in decent condition. The issue I'm having is that there appears to be a bad connection somewhere, neither the headlight nor the tail light come on when in the ON position. The tail light comes on when in PARK but not the headlight...
