Mikuni VM34/110 throttle valve, various cutaways, left/right idle

Genuine Mikuni VM34/110 throttle valves to fit VM30, VM32 and VM34 carburetors.  Made of brass.

Changing the throttle valves on your carburetors may help with tuning.  The larger the cutaway, the more air that will enter the carburetor venturi and the leaner the mixture will be.  Throttle cutaway affects the mixture predominantly in the throttle midrange.  Its usually best to get the pilot jet size, mixture screw, needle height and main jet configurations right before changing the throttle valve. 

NOTE: throttle valves must match your carburetor i.e. a throttle valve with an idle adjustment groove on the LEFT side will only work in carbs with the idle adjustment screw on the LEFT side.  Throttle valves with the idle adjustment groove on the RIGHT side will only work in carbs with the idle adjustment screw on the RIGHT side.

Sold each.  Specify size, idle groove location and quantity.
