A high performance 50cc engine and solid!
Banner
We present here an excellent small high engine 50cc of the original type for MBK 51 / av10 liquid motobecane engine. This P2R kit is an MBK 512 type model because it has 4 transfers, it is in nikasil treated aluminum.
It comes without a cylinder head because it works very well with an original cylinder head. Regarding its performance, you will gain very little, it is above all an ideal kit to start over again at a lower cost while offering you longevity.
The cylinder has a lightly worked normal oval exhaust with a fairly low diagram. The piston is a thin single-segment model to allow more high speeds (reduced friction). This stock mounted cylinder without retouching will give you a very torquey engine capable of pulling fairly long transmissions.
We regret the absence of seals ... Clearly, it will offer additional performance than a true original MBK 51 thanks to its single-segment piston, combining quality / price!
The pack contains:
-Cylinder Ø 39mm
-Piston Ø 39mm
-2 segments 2mm thick
-Piston axis Ø13 X 30mm
-G piston clips
As an option we offer you a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
