Rain Water
What makes the 2GS shut down when going over areas with higher water level ?
I'm curious as it's rain season here and i don't want my baby shutting down on me
i'll try avoiding water in the first place but what if i had to . what should i be careful with ?

I believe the term is called hydrolock.That is a term you do not want to be familiar with.
In automotive terminology, a hydrolock is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-"). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine.
Hydrolocking is often a concern when consumers modify their engines with aftermarket intake systems (e.g. Cold air intake). A cold air intake typically locates the filter near the bottom of the engine compartment to gain access to colder air, which can also increase its chances of ingesting water should it be submerged.
Another reason for it to occur is in the event of the head gasket cracking or "blowing", which causes the radiator coolant to mix inside the combustion chamber.

Thanks to you both
The exhaust is always pushing air out when the engine is running. Due to this, it's very hard to get water into your engine from the exhaust. Well, unless you have a vertical exhaust for some reason and pour water down the top. The intake is always sucking in and the exhaust is always pushing out air. Naturally it's much much more likely/easier to catch an unwanted stream of water through the intake VS forcing water up the exhaust pipe when there are gases pushing outwards already.

If you roll through a puddle just let off the throttle and its less likely to suck water in. You're problem doesn't sound like HL if you have stock intake and you're not driving through a couple feet of water. How many times has it happened. Does it start back up right away or does it take awhile.
