Offroad 4 strokes
Long story I'll try and keep short.
2018 500 exc
Desmogged, full fmf exhaust, vortex.
Sunk my bike in the water. Stood it up and got it running after cranking it with the killswitch off and throttle wide open.
Rode for another 10km and the bike died out of nowhere.
Took it home. Flushed it...
