I have a 2015 sym Jet euro x and I bought a race variator kit with 5.5gram rollers installed it today appears it is much slower and weighed my old rollers and they were 8gram you can feel the power wanting to go but the cdi is restricted so it won’t rev higher than 7/8000 rpm which is my conclusion for the performance not happening anyway my main question can anyone find a de restricted cdi unit for me I will provide pics of mine cheers
