This screw set is required for the MALOSSI reed valve intake manifold X360 if you want to convert a conventional largeframe engine housing (rotary valve) to a reed valve. The key point is the thread adapter sleeves for thread reduction: This adapts the original threads on the engine case to the dimensions required for the X360 so that the intake manifold can be fitted cleanly and without tension.
Suitable for Vespa PX80, PX125, PX150, PX200, T5 and Cosa 125 to 200.
For MALOSSI X360 Thread reduction with adapter sleeve Conversion rotary valve to diaphragm Screws and washers included
On many largeframe engine cases, the original stud bolts for fixing the carburettor are designed for rotary slides. For the MALOSSI X360 reed valve intake manifold, the fixing is solved differently. This is exactly where the adapter sleeves come into play: You remove the original stud bolts from the engine housing and screw in the threaded adapter sleeves. This provides the right thread size for the X360 mounting.
