Hi Nikroc

I searched a little about it and i think it could be the blocking of AIS system, is that correct?

I couldn't found any tutorial for dummies, i found some pictures about the pipe i may need to block but not really sure yet.

During the weekend i will try to look at it in the bike, i also saw the blacked kit from https://www.off-the-road.de/en/XT-66...it-XT-660.html
But i don't want to risk it. Not yet at least until i tried with the cheaper solution
