V-strom goes under water

Hey this is a nice modification to the bike so if there is a flood or a deep puddle the bike will keep going!

I would like to know how to do this modification!

I don't know if that is a modification. The air intake sits up pretty high on the V-Strom, and as long as you aren't sucking water into the airbox, the bike will run.

Exhaust and intake are the obvious first things that everybody thinks of, and they should. As said, both are pretty high, so you can already get through quite a bit of water without causing problems there.

However, there's a lot more things to consider.

The engine itself isn't watertight. The engine breather typically is not an issue as it's required by law to be connected to the air intake (for emission control). But you also have to consider the seals on the output shaft, seals on gear shifters, clutch and such. Are your spark plug connections waterproofed or will they short out? Is the o-ring on the oil filler plug still in perfect shape?

Where do your electric cables run? Are all your connections, particularly the ones down low (e.g. kickstand switch), waterproofed? Where does the ECU sit, or the cabling to any accessoires that you may have installed?

Another issue: When your front/rear wheel hub is at ambient temperature and all of a sudden submerged in cold water, the air in the hub will contract and will suck water in from the stream. This will most likely be through the bearings, washing out any lubricant in there. And afterwards the hub will be partially filled with water, with no easy way out.

Then there's the environment to consider. Except in cases of flooding, like in the video, you don't typically find these kinds of streams in urban areas, but in nature reserves. When you cross it, all the road grime, chain lube and other contaminants will wash off and pollute the stream.

And the last thing: The stream you're crossing is typically a river, not a lake. Rivers flow, and when you're more than knee deep in a river, there's not a lot of current required to wash you away.

I'm not saying it's impossible. All I'm saying is that there's a lot more to consider than just the engine air intake/exhaust, when the water is more than, say, axle deep.

What modification are you seeing?
It appear to me that the motor is not running (No bubbles from exhaust) and he is pushing it with his feet??

Well, the video is about someone who made a stupid mistake but tries to remain cool under it.

In the video the water is simply too deep and will have entered his air intake. Cylinders filled with water will not only stop the bike though a lack of oxygen for combustion, but will also cause hydraulic lock. Either immediately or when he - stupidly - applied the starter about halfway through the video. Hydraulic lock may cause bent conrods, a bent crankshaft, broken cylinder head bolts and a whole bunch of other miserable things.

I would not be surprised if the bike in the video was a total write-off, or needed some very expensive repairs afterwards.

The bike engine stops shortly after he hits the water. He then paddles/pushes the bike past the car. The exhausts are under water and not bubbleing.

This reminds me of the recent video going around of the guy who "jumps" his Chevy Silverado truck over a sand dune only to make a hard landing. When the landing "did not end well" as goes the catch-phase of this season, he got out whining because the frame was racked, the engine dead, and steam spewing from every crevice.

There is no limit to the degree of stupidity due to testosterone poisoning that surrounds such mis-adventures.

Haaaaa, the best mod for clearing that water is to raise the suspension by 2 feet. Maybe pontoons. I think Top Gear could help with that one.

That's awesome. I've always wanted some kind of floating platform that you could drive up on to, lock down the bike and head out across the water with. It would be horribly inefficient but efficiency isn't really the goal.
