We obtained these KEIHIN CR 31mm "Tickler" carburetors in a buy-out.

The carburetors appear to be new or almost brand new.

Apparently these carburetors were designed and used on Honda cb750 race machines .....
then Yoshimura offered them for Kawasaki's and others.

These are the Kawasaki versions with spacing of (2.953 1-2. 3.800 2-3. 2.953 1-2)

      We are not experts on these vintage CR race carbs ......... pretty sure you vintage Kawasaki people know more about these.

We obtained these KEIHIN CR 31mm "Tickler" carburetors in a buy-out.

Spaced for Kawaski race bikes in the 70,s era (2.953 1-2. 3.800 2-3. 2.953 1-2)

The slides move freely ...... the carburetors will need to be refurbished.

Note:

Missing 2 float bowl drain plugs.

We are not experts on these vintage CR race carbs ......... pretty sure you vintage Kawasaki people know more about these.

Race Fairing from the 60,s 70,s era
"Sonic"
Let us know if you have any questions or need measurements.

Dunstall complete fairing, gas tank and tail piece.

This complete Dunstall fairing, tank and tail piece was purchased from a Honda cb750 sohc enthusiast.

Just to be sure ....... we rested the tank and tail piece on a Honda frame and it fits nicely. Although there are no mounting brackets included.

Looks like it could be made to fit other makes and models.

The front fairing has the gauge openings (super cool) and the windshield is dirty but looks in really good condition.

If you are a vintage, rare parts collector you will enjoy the signature "Dunstall" embossment by the gauge area. No fairing brackets.

Really cool stuff from the 70,s area.

This body work is large and shipping could be a problem.

Note:

Not suggesting this shipping option ........... but a customer in the past had us cut a Tracy body in half to save on shipping. (he was a body man and painter)

Also, we get to Milwaukee Wisconsin from time to time and could potentially deliver.
