Ideal for the enthusiast who wants to give a little punch to his engine av7 in all discretion. Here is the cylinder of AIRSAL large diameter Ø45mm (70cc kit) for motobecane motor av7 round (not square). This kit is improved in relation to the origin, the light of amission has been enlarged, the diagrams are revised on the rise.

The shape of the transfers is improved as well, the price is really low for this model. This cylinder has a bi-segment piston, it is delivered complete however, there is no exhaust gasket or gasket. This kit will offer a small gain of high speed and a couple breathtaking at all for a really ridiculous price.

The quality is however present, the cylinder is aluminum, treated with a good nikasil, the finish is not bad, it will be able to make many km without any problems. We still recommend a 17.5mm carburetor, a fairly cold candle (B9) and a very unbridled escapement to get the calories out of this small thermal group, the LEOVINCE SPEED exhausts work very hard on this cylinder stock, if the engine is more equipped we will recommend the muffler WARM UP NINJA, and if you retouch the diagrams, really prepare the engine so that it offers power, the NINJA G2 REPLICA will be the most appropriate.

The pack contains :

-Piston

-Segments

-Axis

-Piston clips

-Leg seal

-Cylinder

-Pipe fixing studs

Optionally we offer a stage 1 preparation, this preparation is a modification of the channels and exhaust light by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification. Allow a little extra time for this preparation!
