Hello people, six months before I had to change piston just to 1800 kilometers due to my faulty oil pump. I went the bike (wre 125 model 2007) to my official husqvarna dealer to do the proper changes and after the replacement when I turned on the engine I saw that the temperature indicator was on and there was also the phrase ecu 2 on the display. I turned on the engine normally but the power is much more low than it should be. The funny one is that when I returned the bike back to the dealer to fix the problem, they told me that they don't know what exactly this is and they need to connect it to a computer in order to set it up but they can't. I searched through the forum but I didn't find something satisfying. Could you tell me what the problem has to do about, and the way it can be fixed as well and the price? Thank you in advance.
