Here is the 50mm RACING kit from PARMAKIT, this cylinder is the largest existing on the market for vertical minarelli engine with the GP1, it has a diameter of 50mm which makes it offer you real 77cc of power and torque! This kit will require machining of the housings to pass it!
It is made of aluminum, it has a very elaborate architecture! Ideal for performance, it has large diagrams, a single-segment vertex piston, a specific high compression cylinder head with polished hemispherical chamber, nikasil treatment 5 intake transfers + large bar exhaust. A real monster to accompany a racing exhaust, very reinforced crankshaft, 25mm to 30mm carburetion strongly recommended ...
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
