Dellorto 6mm Main Jet Kit 10pc for Yamaha Zuma 50 2T

Dellorto 6mm Main Jet Kit for Yamaha Zuma 50 / BWS50

This 10-piece main jet set is made for tuning the Yamaha Zuma 50 and BWS50 scooters, which run a 17.5mm carburetor with 6mm jet threads. The set covers sizes #80 through #125, so you can dial in the fuel mixture without buying each jet separately. It is one of the Yamaha Zuma scooter parts that can help you get the engine running well after changes such as a new exhaust or air filter.

Tuning Options

The kit contains ten brass main jets, giving you a range of settings to match your scooter's setup. Included sizes are #80, #85, #90, #95, #100, #105, #110, #115, #120, and #125, so there is an option for different riding conditions. Whether you are adjusting for the season or for altitude, the range here gives you room to work.

Storage and Organization

All the jets arrive in a plastic case with foam lining, which keeps them separated and easy to find. Every jet is marked with its size, so you can pick the right one quickly during maintenance or tuning. Keeping them sorted this way makes it less likely you will lose one and helps the tuning process go more smoothly.
