  1. CL175 - Fuel leaking out from exhaust

    Fuel Supply and Carburation
    Hello, I am reviving a 1971 CL175 that was not running and was COVERED with rust when I got it. It had been left out, uncovered, on the coast for 3 years. Once I resolved some of the electrical issues that were preventing it from starting, I was able to get it running. This gave me confidence to...
  2. CB450K0 compatibility with K1 exhaust.

    Engine Discussion
    Hey. I'm progressing along in my 1966 CB450K0 restoration and am working on fitting the K1 one piece exhaust pipes that I have. The stock rear mounting brackets from the K0 match the exhaust studs for the K1, but do not extend far enough forward to align with the passenger footpeg mounting...
  3. 74 Honda CB350 Twin Idle Issue

    Miscellaneous Discussion
    Hi everyone! So I'm just going to jump right in. I've recently bought a 1970 Honda SL350 K0 that has a 74 Honda CB350 Twin motor. The bike idles great at around 1,100 just sitting in the drive way and on a quick trip around the block. But when you ride it for a longer period of time it starts...
  4. CL72 on a CM185

    Miscellaneous Discussion
    I’m looking for a new exhaust for my Cm185t and while I looked into the overpriced option of buying a used one seems they fetch crazy money. I did find some reasonably priced cl72 exhausts that look to be a similar fit does anyone know if they’ll mount up straight? I’m fine with making brackets.

  8. Aftermarket exhaust causes backfire

    Engine Discussion
    Theory only on cm400t.... I'm running aftermarket baffled exhaust pipes, dual.... I'm running pods and jetting carbs 125 and 90. The bike runs good for age, with a little hiccup in top-end 2nd and 3rd gear, but cruises well in 4th and takes the juice without a problem. The hiccups are minor and...
  9. CL350 Exhaust problems with aftermarket rear suspension

    Frame, Suspension and Steering
    First time poster but I've been reading for a couple months now. I recently bought a CL350 pictured here and as you can see it didn't come with the stock pipes on it. The exhaust it came with was too loud and low to the ground so I leaped at the chance to pick up a set of stock pipes on...

    Are there other models that will fit a 305? My project came without pipes or retainer rings and there's a moto junk yard here locally that I thought I'd scrounge around at if I knew what to look for.

    Non-Model Specific Honda Twin Topics
    For a few months my wife has complained that her left pantleg smells like exhaust when she rides on the back of my 1970 CL350. Doggone if she ain't right - I could feel two places where exhaust is puffing out. So I remove the pipes today (with an expectation of repair). But instead I find...
  20. 68 CL450 Scrambler tailpipe installation

    Miscellaneous Discussion
    Just to be clear, I mean the six inch lower tailpipe that installs on the back of the lower muffler. I found a NOS tailpipe which the original parts list indicates is the right part for the bike. The covers for the tailpipe are correct for the year, so I have to assume that the mufflers they...
