if the exhaust valve is open when it stalls, yes water can enter the engine. Idle your bike up alittle and this should keep it from stalling out or you could add a exhaust snorkel.

it's just a sealed fiberglass box I have installed on my rack to keep a few tools and things in.

when you say go that the noise goes away, is it when you throttle up or is this noise at idle? Could be a number of things, valves, piston slap, timing chain or connecting rod.

you will have to find out where the noise is coming from to determine what the problem is. sometimes its hard to pin point without tearing into the engine for inspection.

Sinking them usually will catch up with you sooner of later, just some have better luck than others.
