Did you dry or spray off the elctrical connections, coil, spark plug wires etc. Any water on them can effect the way it runs[img]i/expressions/face-icon-small-sad.gif[/img]
When I wash my quads, I start them and leave them running. I try not to spray directly onto the engine or exhaust. Then, I dry it off and spray it liberally with Wd-40. Been doing this for years and never had a problem[img]i/expressions/face-icon-small-smile.gif[/img]
