VM34RS / VM36RS Fuel Petcock Options
You may want to switch to an
Fuel Petcock if you are going to a high-perfromance
These fuel valves will work fine if you are using an "A" model (standard / large) fuel tank.
On certain Kaw 900's and 1000's, however, especially those using a "B" model (LTD) fuel tank,

a high-flow petcock is not essential on a street bike when switching to

top. The undrilled "flat"
By simply removing the handle, and carefully drilling and tapping to 4mm X .7mm 180 degrees across from the original hole, a "reverse" petcock is made. (See pic Below).
Re-install the handle backwards from the original, put
the screw in the new hole, and you're done.
