  3. CX500C wont start after attempted carb rebuild

    Technical Help Forum
    I have no experience with carburators, none, so I thought getting a rebuild kit would be a good first try at working on them, I thought I was doing everything right but obviously I was wrong, I would like to get a set of Murrays Carbs later on but I do not currently have the funds for that...

  5. Rebuild the engine or not

    Technical Help Forum
    Hi everyone, So I'm going through the decision process of whether to rebuild my engine or not, I'm leaning towards no. So before the winter I bought 2 cx500's a 79 and 81 neither of which were running, nothing seemingly wrong with them just nothing attached to the motors to make them run, both...
  6. Compression!

    General Discussion
    I was thinking about trying to get the CX's compression up. 120 psi(L) & 118 psi(R). I'll try lapping the valves and checking the clearances first, but since I have the heads off I was thinking about doing the rings as well. Does this involve an engine pull, or can I get to the rings easier than...

    Technical Help Forum
    Hi all, I have a 1979 or 1980 CX500 (Not the custom model) and whilst I've got the engine apart, I've been convinced I should replace the stator, mostly because it looks like some numpty has damaged the wiring from it by pinching it with a bolt. I found this one on eBay, is this everything I...

    I feel quite inspired by all the other buildposts I have seen so far, so I have decided to start my own :) I have started my "build" one or two months ago and eventhough progres is slow because of work I am still moving forward. The plan is to end up with a tracker/scrambler-ish look. I have...

  19. Caliper Rebuild

    Technical Help Forum
    Front brake on my CX500 is pretty rough looking, some oxidation and pads seems rusted in place. Definitely needs stripped down, cleaned and painted. Figured made sense to buy one of those K&L caliper rebuild kits since the rubber is looking a bit worse for wear, and since dismantling anyway...
