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.
