This new head from Moped Factory is the solution to cooling problems on high output Hobbit setups. Cut from brand new imported big fin Hobbit heads, the head is reprofiled with a large low compression combustion chamber and tight squish band that fits perfecto to 47mm Athena and 46 mm kits. Squish band is set up .5 mm from deck so it will work perfect with most standard aluminum head gaskets, or shim up your base spacing for a little free porting. This head is without a decompression valve.
**Don't forget to upgrade to longer studs and throw out those stock bolts, they wont reach.
