Aluminium casting a 2stroke cylinderhead

[@timbusselot4659]

The bike has been running this cylinder head for a season now. It keeps on preforming. Engine never overheats and she was made for endurance. Next one will be made soon.

I always wanted to find out how they made them but also how they make water ports for engines for coolant

Horrible job pouring the aluminum.

@@mikehoncho5389 some advice to come with the comment? I´m always happy to learn. The part still works perfect on the engine btw
