What petcocks will fit on a 77 550k?
« on: March 28, 2008, 10:46:44 PM »
I need a single output petcock, attached by a nut, not the oval.  Does anyone know which petcocks from other years will fit?  How about this one from a CB450 nighthawk?

It looks pretty similar...

Also, what do you do when parts are discontinued?  It seems like NO ONE is selling this particular petcock... ???

You can replace the rubber packing ($3 or $4) but you need to follow a few steps to get there.
 Drill out the rivots holding the faceplate, then drill & tap for 3mm screws.

Do a search under petcock repair, I did up a how-to deal on this.
