Petcock rebuild kit

[Ivan]

I was at the local shop that is going out of business, and I picked up a rebuild kit for a XJ750, dirt cheap, since they are going out of business.

Any chance this will work for one of my 81 special petcocks? It looks like it might, and has the octy diaphragm as well.

If it won't work, I would rather pass it on to someone who could use it.

I'm not sure, but a quick look at the Yamaha parts site should tell the tale. Check the part numbers for the 750, and then look at the XS11 numbers. If the rubber bits are the same part number, it will work.
