Kit 85cc Ø50mm minarelli PARMAKIT Special GP1 long rod 43mm 80mm vertical stroke scooter (booster rocket, bws)

Attention prohibited on road! Only for competition, in any case does not respect traffic laws.

This is the most enormous kit out for minarelli vertical (booster). This kit is the GP1 model from PARMAKIT (above the RACING, RACE and RACE ONE TP). This is the model kit Ø50mm aluminum for long race 43mm (also available for race origin).

This kit is only reserved to the crankshaft PARMAKIT GP1 race 43mm long and 80mm rod. He will not be able to be fitted with another crankshaft. With its diameter of 50mm and a 43mm long run, the real engine of 84,43cc relatively huge for the small engine booster.

Warning mounting the vilo requires changes and therefore the mounting of this cylinder also requires! The external diameter of the skirt is of 54,50mm bottom and 55mm high. You will have to machine the foot skirt level casings. This kit has really been worked up to bring together all the assets.

First talk about the cylinder, it is a high alloy model range of high quality treated nykasil, the diagrams are very good, admission is completely redesigned for a good filling, the base has been redesigned, as the you will align your casings has it. The exhaust remained commonplace! Oval exhaust a banal but certainly very wide. The axis between 45mm bolt on the vertical minarelli did not let up has an exhaust has booster or bar!

Or he would not have offered the performance of the old oval. Level piston PARMAKIT opted for a pure vertex is flat. This piston has side oilers and is mono chrome domed segment hard pre-rehearsed. Very good material. The cylinder head is a female model (the cylinder head into the cylinder head) in order to have an alignment chamber / bore always perfectly centered! Moreover this system allows not to break the cylinder head gasket that goes very limit with such a bore ... This cylinder head is equipped with a cooling studied, a polished hemispherical high compression piston chamber adapted to the flat ...

Commonplace aluminum head gasket recess was replaced by an O-ring on the kit. The kit also comes with a set of base gasket to make the squish. Clearly this kit really is a working model. With all its assets and report race / Ø well defined, it will be able to offer you the expected performance. However, the assembly is not given to any mechanic ... It will mount the well know and accompany him as it should!
