HD 13/16 Petcock vs CB400F 20mm Petcock?
« on: April 05, 2011, 06:09:53 AM »
I've read that 13/16 and 20mm are virtually the same thing, but would the threading be similar?

If so, we've got another option for the 20mm petcock on the CB400F and some 750s.

So although the diameter would be close, the threading would not?

Someone suggested rethreading the 20mm bung to a 13/16.
