Main jet, size 230 c.c.
Amal main jet, size 230, for carburetor tuning - controls fuel delivery from mid to full throttle.
This is an Amal main jet, size 230, listed under 19-2883 (also shown as 376/100 in some records). The main jet is the fixed-size orifice in the carburetor float bowl that sets how much fuel gets pulled into the main airstream once the throttle opens past the pilot/idle range - it's the single biggest factor in how the bike runs from roughly a quarter throttle on up to wide open.

Our catalog record doesn't tie this specific jet to a named model or a specific carburetor body - it just shows up in general carburetor figures. If you're jetting a bike, match the jet by the size stamped on the part and by what your carb currently runs, not by year or model alone. Main jets are cheap to swap and easy to get wrong, so it pays to have a few sizes on hand when you're tuning.
Call the shop if you want help confirming this is the right jet for your setup - we can talk through carb type and current jetting before you order.
