Kit 70cc Ø44mm MALOSSI aluminum + electronic box calculator for MBK BOOSTER X & YAMAHA GIGGLE / C3 and NEO'S

For the pleasure of all ... Here is the big kit that will give punch to your 50cc 4-stroke scooter! The kit Ø44mm which is in addition delivered with the electronic calculator multi curve. As usual MALOSSI has made a powerful kit, strong, torquey and very high-end.

This concentrated technology will project your engine capacity from 50cc to 66.30cc real, ie performance at appointments! This thermal group has the perfect ratio race / diameter, this cylinder will be easily supported by your original crankshaft.

The electronic box or FORCE MASTER 2 will allow you to change the injection to fit perfectly the new MALOSSI 4-stroke thermal unit. This calculator has been programmed with different programs to be perfectly coupled to your vehicle whatever its configuration! With this box 3 curves are proposed to you ...

- Curve 1: Best performance with the original cylinder.
-Courbe 2: MALOSSI Cylinder and original muffler.
-Courbe 3: MALOSSI Cylinder and modified exhaust pipe.

Let's see how MALOSSI did to increase the performance of the high engine, it is obviously not stopped to simply increase the diameter of the piston cylinder! Here are the technical characteristics of the kit (description MALOSSI):

Cylinder

Bore: Ø44mm; stroke: 43.6mm
Cylinder capacity: 66.30cc; compression ratio: 1:12

-Material: primary aluminum alloy with a high content of tempered and tempered silicon, cylinder liner with application of silicon carbides in a galvanic nickel matrix and smoothing crossed by two diamond passages, with very strict tolerances.
-Usinage: by CNC machine tools with high precision.
-Cylinder piston couplings with coupling tolerance of 0.05 mm.
-Surfaces heat exchanges recalculated and enlarged.

Piston

-Extra compact with three segments
-Material: special aluminum alloy with high silicon content with low thermal expansion with application of tin on the sliding walls
-Usinage by machine tools in CN
-Lightened and reinforced
-Explored thermal exchange surfaces

segments

-Special high sliding and very high mechanical resistance
-I ° segment compression in nitrided steel e chromed
-II ° special cast iron segment
-Segment scraper in three parts in special steel, chromed

With this kit you will be in the position of an ultra robust, powerful and safe! No more mole acceleration, slower spike speeds ... The disappointing recovery! Attention, this kit is still not put in any hands ... Driver warned!
