Vespa Reed valve carb holder for MB PX4 reed blocks (stub adaptor) for 30 - 34mm carburettors, MB

MRB0363K

The problem with the carburettor rubber we used to use on our Vespa reed blocks is that they are prone to splitting.

We think this is because they are designed to work with a motorcycle carburettor that is supported by an air box system and on a Vespa the carburettor is unsupported.

To get round this we had a copy cast in aluminium.

It comes with any new Vespa reed valve we sell or we can supply it as an improvement to the old type rubber.

You need a Malossi type carburettor rubber with this carburettor holder.
