Not a kick starter one -> my is #3614
I dont know if is the bump is "the" technical solution or if it was made accidentally by a wrong action during the fixing process.
The board came back in that state after the first warranty service regarding excessive axial shimmy (compared to 2 other boards), pad runaway and light problem.
We notice this bump on the bearing whitout really taking care of it as a dangerous water entry.
According to the support service that was just cosmetic.....and after my insistance and a second battery burned they admit to investigate the engine for finally find a bad state engine............
Please inspect your board and send me some pics of your bearing if you are concerned by the same problem.....
If i'm the only one to get this after an axial fixing and without any other existing case to give a proof ..........i dont have any other choice to forget my board or pay the heavy bill !
