Quick Overview

The Kehin PWK 28 Main Jet mainly changes the mixture on full throttle openings but changing the size of the jet also affects the mixture throughout the the full throttle range.

The most popular size main jet for trials bikes in the UK is a 125, warmer climates or higher altitudes have less oxygen in the air so require smaller jets.

Also fits CR, FCR, PJ, PWK, PWM, PE, PD Keihin Carbs.

Details

The number of the jet indicates the size of the hole (highest is the largest/richest). Too rich a mixture will limit the maximum engine speed, too lean a mixture will cause seizure so it is often best to stay slightly on the too rich side. Part numbers:
