fuel injection pressure regulator Big Bore Top Performances for Yamaha, Minarelli w/ fuel injection TP-9928130 fitting for MBK YN Ovetto 50 2013-2015,

Fuel injection pressure regulator from Top Performances that increases the fuel pressure of the injection pump from 2.5 bar to 3.5 bar. This also increases the injection volume, since the opening time of the injection valve is not changed (because this is determined by the control unit): A quite simple, mechanical way to enrich the fuel-air mixture for larger capacity, for using a racing camshaft or a racing exhaust system.

The Top Performances fuel injection pressure controller is suitable for the specified vehicles and can be used from 50cc up to 500cc maxi scooters.
