Here is an excellent small high 50cc RACING engine for MBK 51 / air-cooled motobecane av10 engine. This AIRSAL kit is a T6 model because it has 6 admission transfers, it is made of very good quality nikasil treated aluminum! It is delivered without cylinder head, an original type will work and will go very well.
Thanks to its 6 transfers and its mono-segment piston, you will gain in performance, high revs! Indeed, its finish is excellent, certainly does not have monstrous diagrams and a bar exhaust but it will be an ideal kit and a great compromise to ride in compliance while gaining performance all for a ridiculous price.
The cylinder therefore has a normal oval exhaust with a fairly weak diagram. The piston is a pre-ground chrome-plated mono-segment fine model allowing high speeds (reduction of friction). The only criticism that we will make about this kit will be that it does not come with its seals ... but the price is there with an equally visible quality! Clearly, you will understand that this high engine combines performance / super quality and price!
The pack contains:
Piston
Segment
Axis
Piston clips
Cylinder
Please note this kit does not contain any seals, you can find it here!
Optionally we offer a stage 1 preparation, this preparation is a modification of the exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement in the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
