3 of 5 CANNOT use pump gas!!! Wednesday, March 15, 2023
taco eater : John Stevens from Worcester, MA United States  
A little heads up would be nice letting the uneducated know even 93 octane from the pump WILL PING!!! But its a great head otherwise for anyone willing to buy race gas.

I ended up using this head for my Yamaha Chappy LB50 Polini 70cc kit which lets me run pump gas while still giving that needed low end power gain it sooooo desperately needed! https://www.treatland.tv/puch-70cc-puch-70cc-hi-compression-head-p/puch-hi-comp-head-70cc-old.htm

taco eater : Nathan-David Sapanza from San Marcos, CA United States  
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 !

5 of 5 O-ring? Tuesday, September 13, 2016
taco eater : Countryobtunning from Princeton , MA United States  
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.

5 of 5 Puch 45mm O-RING high head Friday, January 31, 2014
taco eater : Timotej Gradišnik from Bistrica ob Dravi, Maribor Slovenia  
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.

5 of 5 Outstanding!! Monday, July 23, 2012
taco eater : Michael Sallie from Canon City, CO United States  
Installed this head with the chappy polini 70cc kit.  Stock studs are a little long so you must use spacers on the studs for yamaha chappy.  Performance was noticeable on the lower end and gave my chappy a little extra punch.  Almost 100 miles at this time and it has remained leak free.  Cooling fins are slightly larger than stock yamaha chappy.

This head has helped solve a head leak issue I've been battling for a while. Checked my compression and it was 240. Uh, whoa!! That's high high.
