Accelerator pump rebuild kit for many of the late 70's and early 80's Honda's. This kit comes with the diaphragm with a 89mm long rod attached, spring, o-ring and a rubber boot for the rod. Get that CB pulling like it should with a fresh accelerator pump! If you're planning to rebuild the carbs and replace all the gaskets, it's a good idea to replace the accelerator pump as well. Check to see if there are any cracks or holes in the diaphragm, if there are, it needs to be replaced.

A good replacement
The accelerator pump in my 1981 CB650C Custom had issues. The diaphragm was shot, and the O-ring was missing. The combination of these two factors meant the bike leaked a little fuel whenever the engine was above idle. After considering several replacement kits, I settled on this one. The only glitch was that the rod on my old pump was only 45 mm long, where this one is 80 something. Some careful measurements and a rotary tool with a cutoff solved that issue quickly enough.
