Product description

The main jet is responsible for making exactly the right amount of petrol available for the premixing. If the main jet is changed this primarily affects the middle and upper rev range. We stock the original manufacturer 6mm main jets of the MIKUNI TM / TMX carburettors in the sizes 85-430. The article number of the jet consists of the part no 4070 + jet size. The greater the designation, the thicker the jet.


SIP-TIP: Use new gaskets when you work on your carburettor.
