I got my new BERG 390 and the first ride after one hour of use the bike stalls and didn't want to run.. At that time I was using a AKRA slip on and I was told that the 390 was not accepting any exhaust till I get the reflash mapping thing in the ECU, so I thought that was the problem..
After that I went back to the OEM exhaust, reset the ECU disconnecting the + batt cable and the bike looked good and was running OK in the garage, one week later (today) I went to the trails and after one hour of use the bike starts failing and shuts down every time I was trying to turn it on, then I start making any kind off electric tests, fuel tests, connectors, etc and every thing was locking perfect, then I tried to start the bike again and the problem was still there but by each time I was trying to turn it on the failure was getting wooooooorse!!
Then I got home and took out the GAS TANK, drained the GAS and took out the fuel pump to check inside and this is what I found;
