This system is often used in cross as it allows for the couple all plans. How does it work ? All simply by a spring system. At low revs there is not so much the gas valve remains down which allows a maximum torque because the exhaust is only 152 ° thanks to its valve. And the higher up the laps it opens up to 192 °. Therefore clear that allows for a maximum torque without denying high revs. Be careful to adjust the valve is also supplied with a spring game. Also this kit is reputed to do a lot of kilometers for aluminum, surely even the most solid aluminum that is have seen on am6 in 80cc. Its piston is in mono chrome domed end hard segment to allow for higher speeds and avoid friction. The cylinder head is a high polished truncated compression chamber.
