PARMAKIT Competition Ø46 to 47mm air cylinder head for 70 / 75cc kit on MBK 51 / av10 / AV7 motobecane

Here is a very rare cylinder head model for MBK 51, this cylinder head is however the best in the world in d.47mm for MBK 51 / av10 / av7 air cooled engine! This cylinder head is first of all increased and has a cross stud in order to cool better, it is very heavy and very massive!

Really impressive compared to other cylinder heads on the market. It is in a version without decompressor, the alloy used is very high-end. The combustion chamber is very good! Made in the rules of art. The squish angle is good, the squish area is zero, the shape is hemispherical.

A very worked model and designed by a great Italian preparer. With this cylinder head model you have to put a long base, and it is still an advantage to install the real competition spark plugs type IW34 or BR10EVX.

It will suit all air kits from Ø45.5 to 47mm.
