Here is the adjustable 9-position pneumatic exhaust valve from ITALKIT for your motorcycles / karting with ROTAX 122 and 123 engine! This complete pneumatic valve kit makes it possible to eliminate the original electrical system which is very often faulty and to replace it with this completely simple system which operates alone (without an electrical system or anything).
With this system, the valve opens slowly and gradually from 6000 rpm to 8500 rpm depending on the desired engine configuration.
You can configure its setting at will thanks to its 9 positions, accessible from the side without any dismantling of elements! The different valve opening adjustment positions are numbered, "1" being the "softest" position (opening the valve at low speed) and "9" being the "most difficult" position (opening the valve). at high revolution).
