aerox minarelli standard head derestriction

[camelaerox56]

hello i am looking to mill out the restrictor in the exhaust port on my standard 50cc minarelli cylinder head on my aerox, it is said that it restricts the engine byaround 35% and it covers nearly half the exhaust port

has anyone allready done it or know the effects?

Thats known as the exhaust port bridge,take that out and you will have a burnt up piston in about 30 min.
It displaces the heat on the cylinder evenly.
Also thats on the jug,not the head,if you want a bit more power ,mill the head .010 " and run premium fuel,should have ALOT more bottom end.
