Ideal for further use of engine housings with defective inlet rotary vane. Adapting the engine housing to the intake manifold increases the flow and performance.
Supplied with gaskets and 2 long M7 studs.
If the set is to be used on engines, whose carburettor is fixed with hexagon socket screws, a mounting kit is still needed (5250049K).
NOTE: Only suitable for Vespa engines with long sealing surface for the carburettor sump. Vespa T5 and some PX80-150 engines have less than 60 mm sealing surface (measured between the holes for the carburettor mounting bolts), in this case the set does not fit. The set cannot be used together with an oil pump.
