Polini Pilot Jet Kit for (42-52) PWK, Keihin Carbs for Scooters & Mopeds

Polini Pilot Jet Set for PWK and Keihin Carbs on Scooters and Mopeds

This Polini pilot jet set is made for PWK and Keihin carburetors that are often fitted to scooters and mopeds. The set includes jets in sizes 42, 44, 46, 49, and 52, so you can dial in the air-fuel mixture with more control. Getting the jetting right matters for solid engine performance, particularly after you've changed the exhaust or air filter. You can find it among the scooter carburetors & jets that may help your ride run more efficiently.

What This Part Does

This set adjusts the fuel-air mixture inside your carburetor, which can help with problems like difficult starting or a rough idle. If your engine surges or bogs down, that may be a sign the jets need changing to improve how it runs.
