Genuine Amal 180 Main Jet for Altitude – Triumph BSA Norton PN# 376/100-180

Description

Use only genuine Amal part! Amal 180 main jet. If you live at over 4000ft you really should be running 180 main jets in your twin carb bikes. Our years of experience here in the mile high city of Denver have shown us that .105 needle jets, #3 throttle slides, 180 main jets and a two ring I.D. needle work the best in most British twin carb twins including 650 and 750 Bonneville, Lightning and also Commando’s with the non cut spray tubes. Same needle jetting but with #3.5 cutaways for single carb bikes and one size down on the main.
