Hello guys, I have now mounted the tuning kit 2 from summer and the box runs fiercely.But what’s even better, the running culture has changed.At little speed no more and less vibrations(3 gear 80 kmh) at higher speeds.I can now turn up the tap in 3 gear at 40 kmh and it accelerates up without a jerk. Fully horny… But what bothers me is the sound of the open air filter cover.Reminds me of my 125 time. But so far only to recommend…. ….
