Petcock versions per year?

[jthiessen]

Is there different versions of petcocks used on our bikes? Perhaps some that will require different diaphragms? I bought a petcock repair kit from Parts-n-more but the diaphragm with those little holes in the corner that didn't line up, and the O-ring that goes on around the toggle wasn't fitting.

The sohc bikes are different from the dohc ones.

What are the differences? My bike is a SOHC, but for all I know the PO could have swapped out the petcock for a newer one.

Post a few pics of it so we can see what you have.
