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.

Hard to find lots of stuff for classic cars and bikes. My mechanic shortened the rod on the pump piece and it works great. The folks at Honda Rebel Forum sent me your way.Time to zoom :-)

This said it would fit my 82 cb650sc. It did NOT say to check the length as some other models did. Well.... It was way too long. Not a huge deal, but not as advertised.
