On a WR450, what is the first item on the bike that will give trouble you when you ride through a deep creek crossing? Between my son and I we have a 2003 and a 2004 WR450. This past weekend we went through several deep crossings and during the last crossing (also the deepest one) both bikes stalled at the exact same time in about 12+ inches of water. We were riding fairly quick in first gear (about 10 MPH) and were splashing some water up. We pushed the bikes up onto dry ground and kicked slowly (no water in the cylinder). After 4 or 5 kicks, both bikes started and ran fine. I am thinking something electrical got wet, and then quickly dried up from the engine heat, allowing a quick re-start. Any thoughts on what happened, and what can be done to prevent it from happening again. Based on this, I am not too impressed with the waterproofing on this bike. Please advise of any waterproofing tips for this bikes, if there are some. My old bike was a RMX250, and it was almost like a submarine.
