whilst riding home in the pissing f**king rain last night i was thinking how does water not get into the engine?

the ram air scoop goes directly into the airbox right? and it must be getting water into it as it was pelting down (and i was on the motorway with lots of spray too) and the filters arnt water proof, and thats another thing if the filter gets waterlogged will the performace noticebly drop off? so is there something somewhere that stops water getting that far ok so rain prolly isnt enough to cause a problem but say ur washing the bike and it gets a blast with the hose

(i was quite bored on this ride as u may have guessed  )

i'm no expert but I wouldnt have thought much rain would ever make it past the air filter even in torrential rain. And what little bit might make it past would possibly either just come to rest in the bottom of the airbox or if it did manage to make it down the intake ports, would just be evaporated off very quickly.

You'd be more likely to suffer some sort of electrical fault through water ingress than any engine problem.

I asked this ages ago as one year I rode to motogp at the Le Mans for 10 hours in the rain

  and there's a drain in the bottom of the air filter box that lets the water out    and next time you find your mind on other things in bad weather like that ....(wake up) as its times like that things can go bad    don't let your mind wonder

it was 11pm the m-way was fairly quiet and my mind didnt really wander that far lol

so what about the air filter getting water logged?
and what if a hose got sprayed up there with the engine running?
arnt the (dont know what there called on a bike) intake manifolds directly under the air filter so any water that drops into the engine so if enough water went in there would it cause a problem or is there something to stop any problems arrising, i know cars are vulnerable to deep puddles and the like but it just looks like with the ram air bikes are more so unless theres something i dont know about................................................like witchcraft

i know a small amount of water in the engine is not a problem my car has awater injection system to add water to the air just before the inlet manifold

Whose going to be daft enough to spray a hose into the intakes with the engine running?

 Only one way to find out what happens....... Give it a go

[tingy]

well maybe not spray a hose in its just an example  how about someone throws a bucket of water over you while ur riding past or a car coming the other way hits a large puddle and sprays a load of water in

not concerned with how it gets in just pretend its got in 

[NinjaPaul]

There's no direct route for water to get into the airbox, several objects in the way along the way for water to bounce off and slow down such as the headstock stem for starters, then the airbox intake passages and the filter itself. Air filters are already wet with oil so getting water on it doesnt change much really, other than maybe slightly altering the fuel air mixture temporarily.

Unless you're gonna turn your bike into a submersible it would most probably keep running. If someone threw a bucket of water at you as you rode past, I reckon the shock would be more likely to cause you to crash than the bike cutting out.

I've been caught in some horrendous downpours on my 06 that have lasted an hour or two and have never had a problem with water causing running issues and as they other guys have mentioned there is a drain hole in the bottom of the airbox for it to drain out anyway.

The way I look at is that Kawasaki where clever enough to build an amazing bike like mine I'm pretty sure they were clever enough to consider what happens in the rain.

They probably didn't anticipate people squirting hoses or anything else in the intake tho..... But even if you did manage to point  the hose in the intake whilst cleaning I don't think it wouldn't do any harm as long as it was only for a second or two.
