  1. Opinions on replacement exhaust

    General Discussion
    Interested in replacing my stock exhaust tips on my 78 CX500. Not really looking to overhaul the whole system and would ideally like to find some nice, sleek, smaller tips. (Hate the stock cone shape.) Most of the ones I have found make the bike sound louder and I would like to keep it quiet as...

    Where Can I Find...
    Hi Everyone, This is my first post after recently deciding to push my project a bit further. I'm trying to figure out if its possible to remove and replace the H box with an aftermarket exhaust that doesn't require any sort of welding or metal working. I currently don't have access to any...
  3. New Exhaust Gaskets Fixed Everything

    General Discussion
    Recently I've been trying to get Jenny's carbs dialed in as perfectly as I possibly can. I have the carbs synced with virtually 0 difference using a DIY water manometer. The engine evened out noticeably after the sync, but I was still getting symptoms of a lean condition. The engine was...
  4. Left exhaust weaker and backfiring.

    Technical Help Forum
    Hi everyone, sorry I know it looks like I'm posting question after question but I am dying to get my project finished. I think the best way to explain it is that the right side runs consistently with a solid "thud" from the exhaust every moment whereas the left side is more of a "puff" with a...
  5. Making Loud Exhausts More Quiet

    Technical Help Forum
    I purchased a pair of Megaphone exhausts for my rebuild a few months ago (now beyond return warranty) and after having them fitted and run for a while it turns out they are far too loud. I have looked at them for a while and doubt that they could be disassembled to add a plate to the baffle. The...

  9. Adding Pods but keeping Side Panels?

    Technical Help Forum
    First posting on here - I'm working on a 1980 CX500 and have a questions about the air/exhaust. My plan was to remove the H-box and run straight pipes. I've heard that with straight pipes it's advised to increase airflow and re-jet. I have the jets and pods needed but I'm wondering if there's a...

    I'm removing the box under the bike and getting Murray's upswept pipes for a pair of Harley Sportster mufflers I bought used last Fall. Pipes not ordered yet, waiting for a total from Murray because I'm in Canada, so can't measure anything yet in terms of buying/making a bracket. Just wondered...
  12. Changing the slip-on.

    CX Customization and Mods Forum
    Alright, I understand the purpose of the H-Box. For this reason I intend to keep it on the bike. However, the megaphone mufflers of my 79 CX500C are in need of replacement. I don't like their look and would like to add something that looks a bit more clean (clean, referring to the look, not the...
  13. Dual to Mono Exhaust Conversion

    CX Customization and Mods Forum
    I want to change the exhaust on my '82 CX500C from dual exhaust to mono, (single tail pipe), solely for looks. I plan on removing the Hbox and fabricating my own header and muffler. I'm not looking to buy anything as I'm poor and cheap. I also plan on switching to a single pod,(if I can design a...
  14. Exhaust fumes

    Technical Help Forum
    Hi all, I have searched everywhere but cannot find an answer. I have a GL650i with full fairing. The exhaust is running clear but if you blast the throttle to 6/7k it will emit a cloud of black soot. The bike has done 32000km,(about 20000 miles) and has been stood for a long time so I suspect...
  15. Quiet Mufflers

    Technical Help Forum

Right now I just need them on to get the bike running and not angering the neighbors. Winter, I'll take it down to the frame and when done...
  16. One exhaust is pushing out more power than the other (dual)

    Technical Help Forum
    Noticing lately that I'm burning oil (or so I believe) in my right cylinder. Reason I state this is on some starts, I'll get whitish smoke from my RH exhaust (not condensation at all), as well, tiny droplets of black splatters on my rear differential. Also, when putting my hand at both ends of...

    Technical Help Forum
    All, This weekend I installed a new h box on my 1980 Cx custom, it took literally all day to get all the pipes back on as they didn't want to line up perfectly. I'm have Harley cans on the back installed by a previous owner, before I took it all apart and re-installed it was not backfiring. I...
  18. Building a custom drag pipe with baffles? Is it worth it!?

    CX Customization and Mods Forum
    Hey guys, I just took off my mufflers, and I love the look. Fits great with my build! But I dont love how loud it is... Australia is a bit strict on their volume rules, and I hate feeling like a doucher when Im cruising in the city. I had a thought the put baffles in straight pipes, and...
  19. H-Box Problems

    Technical Help Forum
    So with the weather finally clearing up, I had the time and room to take apart my exhaust and take a look at my rusty old H-Box. After cleaning some of the rust off, it looks as though it is still structurally sound, but I had some of this stuff falling out of it, and I can hear more rattling...
  20. Carburetor problems...how do I adjust?

    Technical Help Forum
    Hey guys! Just took the CX500 out for a ride today and noticed that when I really got into it accelerating up a hill, the engine would pull fine until around 5500rpm and then it would bog down. Almost like it had a rev limiter. The bike runs great and has tons of power up until that point. I...
