old school---i think you're worrying too much. the only bike i ever drowned was my old suzuki 185---did it twice. the air box had nowhere close to the kdx's ability to avoid water and still it was very hard to kill. it took sustained water up to the seat to kill it---a quick splash that deep had no effect. besides, it's easy enough to get back to the truck, if you soak it. just turn the bike upside down, pull the plug, put it in gear and spin the back wheel 'til the water stops coming out---the fun part is the 50 yards or so of push starting before it finally catches on and runs. it's not a big deal---ride on, my brother!!! :thumb:
