This is our bare casting (finished with options) sale code to childish concepts Facebook followers. Delivery time may be as far out as 6 to 8 weeks depending on how this sale goes so please be aware of this when purchasing.

This head comes as pictured as a bare casting with seats.

We can finish it for you for extra or send as shown. They are my favorite head for use with a 25/28.5 valve 5.5 mm stem combo (the seats need to be opened up a little for that) and a VM22 carb and flat mounting of the engine such as what's common on a mini bike. The chamber size is 18cc and the exhaust bolt pattern is just slightly wider than a standard clone/predator head but you can still use a standard pipe if you oblong the bolt holes. These are limited quantity

Note: the stock seats in this head are .975 +/- .010 (intake) and .845 +/- .010 (exhaust) ID even though they are supposed to be called 24/28 mm you will want to open them up some for the best flow. I like to run these at .885 - .890 exhaust id and 1.025 intake id for the standard 25/28.5 valve combo. Yes, the seats have plenty of material to make this possible.
