Aqua Ingress/Pissing water

[Commuter_Tim]

So since it started raining, I immediately died due to lack of WipeyPal...

Well no but it appears my bike may be dying...
2 weeks ago my bike started chugging along after filling up petrol Would try to stall and barely idle at more than 900rpm (idle is normally around 1500rpm)
The exhaust sounded like it was producing weak farts on every combustion.

I thought it may have just been some shit/water in the fuel so ran it for a while in hopes to burn off the water.
It idled fine the next morning.
I emptied the plugged rubber hose at the bottom of the bike (crankcase breather?) and approx a third a cup of water came out.

A week later the problems returned (without filling up this time) again managed to burn through it, and emptied a third cup of water again.
Even though the idling issues have not returned in over a week, I have been emptying that plugged up hose on a 48 hour basis, and there is a considerable amount of water each time.

Where should I start looking for water ingress first?

EDIT: My Bandit lives outside without a cover, this only really seems to be happening when its raining overnight, hard to say if that's the cause though.

Finding what the hose is would be a first step. What's it connected to?

Is it actual water coming out of it?

What is plugging the hose up each time?
The only time I've had a drain hose plug up I blasted it clear with compressed air (from the top end) and a dead wasp shot out the bottom. The little fucker.

If it's the airbox drain and you're getting a cupful of WATER in 24h, I suspect the cause will be obvious as soon as you take the saddle/tank off.

If it's petrol, I'd suspect you have a blocked/leaking needle valve or punctured float.

@jnw010, airbox drain hoses often have a bung in them. It's just there to drain out any condensation. You'd normally get a few ml over a period of months, no more than fits in the tube itself.

Anyone know why the drains are blocked up?

Why not just just let em freely drain...?

Thanks for the replies

It was certainly the Airbox drain hose thanks, the amount coming out seems to be lessening as only about a tablespoon or 2 came out this time.
It's definitely water too as the ground was already wet, and it immediately blended with what dropped out, no oilyness.

The rubbers from airbox to carb look perfect, no cracking or damage I could see, which is odd considering it's a 21 year old bike.

I did take a quick look at the filter, and it seemed a little dusty but by that point it was almost pitch black.
I guess I'll have to pull it all apart properly on my lunch tomorrow to get a proper look at the air filter in good light.

So I had the tank off/Air filter out, no damage/holes I could see.

However after I filled up with petrol again and left sitting overnight it started farting out the exhaust, underpowered and idling about 1000 instead of 1500 again.
Again dropped petrol from carbs, blasted the engine for a bit, and it was all good again.

Is it possible if water dripped into the tank during fillup, it could end up coming out of the airbox drain? (evaporation blasting back or something?)

"""""I should mention as it may be relevant, when I first purchased the bike I left it on "prime" and it flooded the engine and also out of the same plugged hose.
I have had no reliability issues in almost a year other than this.""""""""


Prime (pri) is used when the bike has not been used for a while, pri will fill the carbs up to the correct level for starting. Your carb/s are overfilling and need sorting first.
A bike should be covered ( ignition switch and tank) when not in use.
Your tank overflow outlet needs checking for when you put too much fuel in above the neck or if water gets in around the cap.
Also the idle / tick over should be 1.000rpm to 1,100rpm and no more.

You're SURE it's water and not petrol? Because that's a hell of a lot of water to be getting into your airbox from somewhere in an air cooled bike.

In case anybody else has this issue, I finally appear to have sorted this....

The seal around the airbox cover is made of something similar to that 1mm foamy sheet you get layed over the top of the cheapest socket sets on Ebay.
It is cheap, shit and fucked, causing water to pool in the airbox, fill up the plugged hose, and overflow through the air filter into the carbs.

I have noob bodge fixed it with Hylomar Blue and its been fine for a week with a fair bit of rain here and there. (I'm aware that's not its intended purpose, but it was to hand)
All going well I'll source a proper seal, all going wrong the Blue got into the carbs and gummed shit up.

Cheers fellas

I'm still impressed at the physical quantity of water getting in.

I'd have gone with silicone but hylomar will probably do it.

Might be worth a new filter too if this one has been soggy for a long time.

weirdly, my Bandit does something similar in the rain.

In the dry it idles happily, in the wet it idles much slower on the verge of knocking/ spluttering an dying.

I have sat there an held the throttle open a touch at the lights to just keep it going

cheers will check the seal on mine
