MAIN JET- MONOBLOC MK1 MK2
Main jet, size 240, for Amal Monobloc Mk1 and Mk2 carburetors.
This is a main jet for the Amal Monobloc carburetor, Mk1 and Mk2 versions, sized 240. The main jet controls fuel delivery through the mid-to-upper throttle range, and it's one of the parts most riders end up swapping around when they're tuning a Monobloc-equipped bike for a particular exhaust, air filter, or altitude.

The number 240 refers to the jet size itself, so when you're ordering make sure it matches what your carb needs rather than just grabbing whatever's on the shelf. If you're not sure what size is currently fitted, pull the old jet and read the number stamped on it before you order a replacement.
We don't have much more history on this one in our records beyond what's on the part itself, so if you have questions about compatibility with your specific Monobloc body, give us a call and we'll sort it out before you order.
