F2 Racing Air Screw O-Ring
Posted March 02, 2010 - 08:23 AM
The F2 air screw that came with my bike did not have an o-ring. I would like to order one from mcmaster but don't know the size. I am not near the bike to measure one or can I find the correct size since F2 has evaporated.
Much appreciated gang.

It is the same oring.
Not they are different. The small o-ring at the tip of the fuel screw is very small in comparison to the o-ring that goes on the main shaft of the fuel screw. The oring on the shaft helps keep dirt and crap from getting into that cavity. It also has the added benefit of stabilizing and preventing the fuel screw from backing out.
