Review on 🏎️ Ultimate Performance: Black High Compression Racing Head for 2 Stroke Engine Kit 66cc/80cc Gas Motorized Bicycle by Darryl Montagna

Love the extra power. It looked way better on my standard top hat, but I twisted it so much that the hairline broke my standard top hat. This head has clocked over 1000 miles since I installed it and I love every second. He's been through quite a brutal life since I took over and he hasn't left me yet! :D Most people avoid this head but if you get DONSP1986 from the seller you will love it. Quality head at a competitive price. I recommend replacing the acorn nuts with a standard nut, otherwise you won't be able to tighten them enough. Don't overdo it and you'll be fine! :)
