Test for leakage

[dna9656]

How are the carb diaphragms tested for leakage?

Is there a carb rebuild kit available for the 83 year model bikes?

Unless it's an obvious tear, hold the diaphragm up to the light to find any pins holes....

remove the slides and a bright light will show holes and tears. FYI- the caps have a sharp inner edge that causes tears.... sharp edge later removed on the 1300 caps. This edge can be sanded away with 400 paper

New diaphragms are available here: http://jbmindustries.com/index.html

They do mount differently, but we have tried them and find them to work well so far, 2 years and counting.
