Here is the brand new 70cc kit from AIRSAL. After a great success in the AIRSAL aluminum kits and following a strong demand, AIRSAL is finally releasing its large diameter cast iron kit for 50cc am6 motorcycle engine! You should know that a cast iron kit is more solid on long journeys, so it allows additional reliability but it gives a little less power than an aluminum kit because it gives less freedom to the piston (less cylinder expansion) and less good heat exchange!
This model is Ø48mm in diameter, or a real 70.5cc! It is a very good high engine, very well finished which will bring much better performances to your machine without denying the solidity. It is of course equipped with a two-segment piston to preserve the torque, a cutout of the rear of the piston is present here to improve scanning. it has 5 transfers, the sides of the base are well worked. The internal sides are nicely drawn.
In addition, it is sold with an aluminum cylinder head with a high compression hemispherical chamber.
In summary this kit will give you very good performance especially in low speed torque while having excellent strength and good power, all for a very low price!
We recommend accompanying this kit with : 21mm carburetion (0.30mm or 0.35mm carbon valve slats), reinforced crankshaft and bearings, racing muffler, racing spark plug, etc.
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!
