Wow!... slapped this puppy on and it improved the low end torque right away.... the powerband hits hard at 4500 RPMs so I’d move alittle forward on the Ped if I was you... Puch Maxi, 17x38, Boss pipe, 17mm Bing Clone (wide open Choke) Supreme Fuel (no Booster).. thanks Dana. Treatland !

This head works really well! I had a cylinder head mating surface that was bitten by jaws and this baby sealed it up! Only issue is I always battle with sealing up the spark plug on these aftermarket heads mybe a copper washer that I can really crush will fix all that

Noticeable power increase and the fins don't vibrate like the k-star head I replaced.

Love this thing, using it on my athena ajh reed kit and I'm getting 200psi cold compression. This head rocks.

Puch 45mm O-RING high head

This head looks fine. The combustion chamber is nicely finsihed. Well se, if this head will stop my sparkplug leaking.
The old head wich I used for Athena AJH 70ccm, was leaking from the sparkplug hole. Maybe the thread was poorly finished.
The combustion chamber in this O-RING head is HIGH, HIGH - awesome in comparison to classic cylinder head.
Hold on, here comes the powerband
