Hi I have a 2011 sherco 290. A couple of weeks ago I managed to submerge my bike nearly completely under water. After doing this and a lot of kicking over I managed to get it going, and went fine for the rest of the day. A week later I rode it and was fine but a week after that I had no spark. I have changed the plug and tested the kill switch. I took the flywheel cover off and found some water in there. I have cleaned the rust from the stator but still have no spark. Just wandering if anyone has any idea on what to test next, thanks!
