Prima Dellorto 6mm Main Jet Kit 10pc - Zuma 50 2T

Find the right fuel mixture without ordering jets one at a time. Prima's 10-piece 6mm Dellorto-style main jet kit gives you sizes #80 through #125 in five-size steps, ready for tuning a compatible Yamaha Zuma/BWS50 2-stroke or another scooter running the same 6mm main jets. Whether you've changed the exhaust, air filter, or cylinder, or you're adjusting for elevation or seasonal conditions, the included foam-lined case keeps every size together and easy to identify.
