Needle valve KIT 2.0 for carburetor RS34-40 MIKUNI

MIKUNI offers this float needle and seat kit. In the carburettor bowl, a float rises with the fuel level and pushes the needle against its seat to cut off the supply.

Why replace the needle and seat?

The benefits:

• Put an end to overflowing and fuel leaking from the overflow pipe.
• A stable bowl level: the carburation stays consistent from idle to full throttle.
• New needle and seat together: they are made to seal perfectly against each other.

Why choose MIKUNI?

Mikuni, founded in Japan in 1923, is known for supplying carburettors to many major Japanese manufacturers; its TMX38 is original equipment on Yamaha YZ125s and KTM 150 and 250 two-strokes: Mikuni jets, needles and slides are the original parts for these carburettors.

When should you replace this part?

Fuel running out of the overflow, an engine flooded at start-up or a groove worn on the needle tip: it no longer closes, replace the kit.
