We have recently introduced a "low fuel inlet" modification for all VM type carburettors.
The modification can be made to all VM30, VM32, VM34, VM36, VM38, VM44 carbs.
This is really useful in applications where the fuel tank is very low over the carburettor such as Velocette Thruxton / Clubmans type tanks and the BSA Goldstar, or on pumped systems such as racing karts using a low fuel tank.
The modification allows a much simpler fuel pipe run and ensures the full contents of the fuel tank can be used.

Despite strong demand for the reintroduction of many discontinued carb parts to support the classic bike movement, Mikuni are going the other way and ceasing manufacture and supply of many items every month. They don't seem to have a care for the customers who buy their product and are disconnected from the reality of the classic bike business. That said, as more carburettor parts become obsolete and no longer available, we are having small batches of quality replacement parts manufactured where we see there is a demand.
Look on the New Replacement parts page to see what the latest items are. Many OEM parts can be supplied by slight modification to genuine Mikuni parts which are still available.

If you have recently bought a cheap Chinese carburettor on eBay or Amazon for an ATV Arctic Cat etc which is branded "Motorcarb", please don't contact us about it.
We have no connection with this enterprise, their product or after sales.
