This engine goes hard and with the extra torque, it out accelerates the 29.5cc.
This engine has a Zenoah 2mm crank, fully modified crankcases set up perfectly, beautifully hand-ported cylinder with Rooster Tails special combustion chamber and milled, modified and lightened piston. How can you beat that?
This combination produces huge increases of power everywhere and an even larger increase of torque, while still retaining the ability to rev really high.
If you can handle it, and you want to be out in front, you'll need the 30.5cc from Rooster Tail Engines.
