Servas- I’m just making my sportster (Ez 2016 is but model 2017). I now have 5200 km, of which about 95% with Aral Super lead-free. For the few km very strong deposits in the combustion room and also already in the intake area or on the valves. So nothing increased but for the few meters already crass I find. At least up to the combustion room I expected new value. Far away from it! I thought something good but with the result I refuel from now on cheap. Or I try a lot t with Shell. Same great propaganda. Let’s see… What experiences do you have? Greetings Michi
