Genuine Amal 190 Main Jet (1) – Triumph BSA Norton PN# 376/100-190

Description

Use only genuine Amal parts! Amal 190 main jet (1). If you live under 4000ft you should be running 190 main jets in your twin carb bikes. Our years of experience have shown us that .106 needle jets, #3 throttle slides, 190 main jets and a two ring I.D. needle work the best at sea level and above 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.
