750 K7&8 petcock
« on: August 02, 2011, 03:38:29 PM »
There is hope for replacement of a K8 petcock if you don't want to take it apart, find gaskets, and tap for screws etc.

http://www.cb750supply.com/products/6/fuel-system/67/petcock-parts

This one listed for the '77 models will fit, the main difference being the outlet is toward the rear rather than in toward the engine.

I just turned it around 90 degrees, or you could get a little longer piece of fuel line.

The price is right too!

No problem!

I found this part number (16955-268-020) in another post for the replacement 4 hole washer, so I can now rebuild my old one and have a spare.

Anyone know a part number for the tabbed washer that sits in the groove of the nut thet screws onto the tank?

I found an o-ring that fits, but haven't tried it yet.

I know...old topic, but feeling lucky!

How have these worked out?  How is the look/quality compared to the originals??

My K2 has a leaky petcock so am considering one.  Thx

I like my women a little big. Natural. Now, they shave this and wax that. It's not right. I love natural women. Big women. This trend in women has to go. Bulomia, anorexia. That's just wrong.

Well, lucky you are....I'm still here and so is the petcock!

We just celebrated our first anniversary a couple weeks ago, and hasn't leaked a drop since installed.

Looks as good as new, just turned 90 degrees so the stock hose could be re-used.

 I fixed the old one, just haven't seen the need to put it back on.
