Hi guys im not sure where to start, i took my Wr400 last weekend offroad. After coming across a very deep creek i decided to cross, the bike made it through fine but not the second creek it stalled as i was driving out. Ive taken the air filter out it was wet through cleaned and dried , purchased a new sparkplug the bore has a white creamy substance in it. Ive checked for spark and there is spark there, is this just because everything got wet or im i looking at a more serious problem. The bike still wont start, any help would be good..
