With its two-piece plunger head, its single-piston piston has flat cap, compression ratio of 14: 1 and its high diagrams, here is the ATHENA RACING PRO version for motorized scooter PIAGGIO / GILERA liquid cooling. This very high quality kit has a EUROCILINDRO nicasil treated aluminum cylinder, very robust. A flat plated piston with a single segment to allow the highest speeds, a high-compression cylinder head with a tapered chamber offering a compression ratio of 14: 1, partly for better cooling. The recommended squish is 0.70mm. It comes with the carbon flap valves suitable for the regimes obtained by this kit!
Use only SP98, a crankshaft reinforced with bearings with a set of C4, a carburetion in 21 to 28mm, a muffler racing, a racing variator and if possible, a variable advance ignition ...
Ultimately, it is a very powerful and robust kit to accompany and mount correctly! It also exists in standard racing, cheaper but with standard cylinder head.
