Here you find all the intake valves, a box flaps, flaps slats ... For motorcycle engine DERBI euro 1 & 2! Ideal for increasing its power, torque, acceleration, speed, approaching the most of the power system and improving its passage. valves of the slats must resonate more or less late, soft blades and in low quality (steel clicking ...) leave very early passing the gas mixture in good quantity but bridera (will resonate frequency) too early! That is why we prefer to use a fiber lamella or more carbon to properly erase the harmful vibration by increasing the thickness, we can get in clamping frequency later and thus free up system! Generally it is recommended: -for an original configuration 0.25mm -for an average configuration 0.30mm 0.35mm -for a high speed configuration -and finally to a very high 0.40mm scheme configuration. Obviously, some parameters such as the advance ignition, exhaust, diagram, the diameter of the carburetion and diffuser system will vary these parameters! The slat type will also vary (3 strips on each side or 2 strips joined together or not ...).
