Unapproved part! Only reserved for competition, closed circuits and tracks.
Here is the 70cc AIRSAL kit for vertical minarelli (booster…). This Ø46mm model has a very good power while also increasing the torque of the scooter! All while preserving great strength. The cylinder is an aluminum 5 transfers + addition in skirt, high quality nikasil treatment, standardized oval exhaust ...
The cooling has been very well thought out! Admission has also improved somewhat. The piston is a two-segment model (including a hard chrome domed for the top of the piston), this piston has two rear machining operations for a marked improvement in filling / scanning.
The cylinder head is a high compression model with a hemispherical chamber with a polished finish. Clearly, this kit is very solid, it offers great torque but also good power. Nothing to do with 50cc ... It also has an unbeatable value for money!
We advise to accompany this kit with minimum: carburetion of 17.5mm (in PHBG), crankshaft and reinforced bearings C3 game, racing exhaust, cold racing candle (B10 HS or summer and B9HS for winter).
This pack contains:
Aluminum cylinder Ø46mm nykasil
Bi-segment piston
Hard chrome domed Ø47mm segment + standard segment for the bottom of the piston
Reinforced piston pin Ø10mm
Piston clips (axle rods) in G
Complete reinforced seal pack
Polished hemispherical high compression Ø46mm cylinder head
Notice
Optionally we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement in the piston and bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
