Look, we’ve all been there. You just picked up a new classic Honda-this time it’s one of Team Red’s tiny, mighty 175 or 200-series bikes-and despite your best efforts, it just won't run right. You dig a little deeper and, surprise surprise, you discover that the carburetors are a disaster. Don’t fret! Luckily, the little Keihin round slide carbs Honda used on the CB175 / CL175 / SL175 / CB200 / CL200 bikes are simple and easy to work on.
In this video, Brenden walks you through the process of disassembling your carburetors to get them ready for cleaning. In his step-by-step narration, he takes time to explain each part and how it relates to other parts as he removes the float bowl, jets, slide assembly, and other parts. He even shows us how to gently remove a stuck float pin without destroying the carb body casting.
This video covers the following topics:
- Removing the slide and disassembling the slide assembly
- Removing the jets and associated nozzles
- Removing a stuck float pin
- A discussion of the throttle cable, slide, idle mixture screw, and idle speed screw.
Once you’re done learning how to take these carbs apart, check out our videos on Reassembling CB175 / CL175 / SL175 / CB200 / CL200 Carburetors and Syncing CB175 / CL175 / SL175 / CB200 / CL200 Carburetors.

Best video on the internet for these carbs, great job, I learned new info! I have a 1971, still having some carb issues, I'm going to pull them off again and follow the video, make sure I have everything together correctly.

Love all you do for the vintage Honda community. It would be helpful to mention you're using JIS screwdrivers and it would be super helpful to cover some of the carb problems that you can run into and how to remedy. This sounds like a topic for another video. One I've seen numerous times is one of the towers for the float pin being broken off. (Was able to save the day by drilling into both pieces and bridging with a small metal dowel.) Another is the emulsifier/main jet tower being corroded or having a part of it being broken off. Maybe to mention what one could use such as a fuel safe epoxy to save the day. Oh and a last killer that was really confusing was a time the new bowl gasket was too large and when I put the cap on it was pushing on the float and sticking it in the open position, thus spilling fuel all over my garage overnight. This was fixed by cutting down the gasket to make it smaller. Love doing business with you all and thanks again for facilitating people to save their bikes and make them happy!

Ditto on the above comments. By dumb luck I have my SL175 running pretty well (esp with your Shockwave electronic ignition!), but I maybe should go through the carbs again with this extremely helpful guidance!

Thank you I enjoy your videos. I have a CB175 and I worked on the carbs for a long time trying to get them set after an engine rebuild. Finally figured out the float needle seat and its gasket was leaking around the threads into the float bowl making it run rich no matter how I adjusted the carbs. I ordered OEM seats and gaskets. Smoothed up some pitting where the gasket contacted the carb body surface. This is after I finally figured how to test the seat for leaks. Thanks again.

when measuring the float height, should it be done from the lip above the surface or the flat surface? I've read different thing in different forums with no conclusive answer. Trying to use the float height tool from the flat surface is impossible with these cb175/cb200 carbs.
