PROX Pilot Jet for MIKUNI carburettor for KAWASAKI, KTM, HUSQVARNA, GAS GAS and SUZUKI 1982-2026

The PROX pilot jet is designed for KAWASAKI KDX 200, KX 65, KX 125, KTM SX 65, SUZUKI RM 65, HUSQVARNA TC 65 and GAS GAS MC 65 from 1982 to 2026. The pilot jet meters the fuel at idle and at small throttle openings, up to about a quarter. It is what makes for clean starts, a steady idle and good pick-up out of tight corners.

Choosing the right size

Adjust the fuel screw first. If it has to be opened or closed beyond the range given in the manual, go one pilot jet size up or down.

When to change it?

• Unstable idle, engine stalling or “hunting” at small throttle openings.
• Fuel screw having to be turned outside its normal range to get a good idle.
• Change of season or altitude.

When the fuel screw is no longer enough to get a clean idle, or when conditions change significantly (altitude, temperatures).

Fitting tips

1. Turn off the fuel tap and drain the float bowl.
2. Unscrew the old jet with a suitable screwdriver, without damaging the slot.
3. Screw the new jet in by hand, then tighten it lightly: it's made of brass and deforms easily.
4. Test-ride the bike and check the spark plug.

Frequently asked questions

Why a pack of 5?
The jets are sold in packs of 5 of the same size: enough to equip several carburettors or keep some in reserve.

Is my carburettor compatible?
Check the carburettor brand given in the product name (Keihin, Mikuni…): the jet must match the brand and jet type of your carburettor. If in doubt, compare with your original jet.
