Beginning the CB900C Carb Rebuild

It’s been a while since I’ve done some work on the bikes (winter time projects were in the way).  Bringing the CB900C back to the middle of the garage, I fueled her up to see where the project was left off.  Engine started after a bit but still running rough.  Taking some quick temps, I noticed that the header off of cylinder 4 was much colder than the other 3, so it’s time to pull the carbs, give them a clean, and see what’s really going on.

After pulling off the carb pack, I started breaking things down to single carbs.  After stripping a few of the screws on the braces I finally started getting into the single carbs but needed to break for the night.  Found a great reference for breaking these carbs down here:

Definitely will be making my way through that document in hopes of getting them back together.  Will post more and pictures as the project continues.
