Main Jet Part Numbers (Mikuni TMX-34)
Main jet part numbers are the same as Mikuni VM carburetors.

Throttle Valve

The throttle valve controls the rate of engine air intake
by moving up and down inside the main bore. At small
throttle openings, air flow control is performed chiefly
by the cutaway. By controlling air flow the negative
pressure over the needle valve is regulated, in turn
varying the fuel flow.
The throttle valves are numbered 1.0, 1.5, 2.0, etc.,
according to the size of the cutaway. The higher the
number, the leaner the gasoline/air mixture.
