Can't determine where a loose hose attaches to

JunaryBunch · September 28, 2006, 09:45:25 AM

Few days ago - noticed a small puddle under my bike. Found a hose that was not attached to anything so I tried to figure out from where. Obviously I could NOT.

It is a little hard to describe. One end is shaped like an "L" which implicitly would attach to something. The other end is not attached to anything. The end that is not attached to anything is coupled with another hose located next to the right rear brake pedal. I cannot find this hose in Clymers and was hoping someone might be able to assist.

I drove it home without any problems. After parking it, I did notice a bit of leaking (but only a few drops). So I am not sure if the leaking is directly related to this unattached hose.

thanks

Battery vent hose springs to mind.

what kind of liquid is being dripped from it? Could be battery vent, could be air box drain. Look underneath at the airbox. There should be a drain hose attached to it.

I'd suspect either the airbox vent or the gas tank vent hose being the one un-attached. BTW, those two and the battery vent hose should be "gathered" at the point where your describing. The battery vent hose connection is easiest to check, of course, being viewed w/seat removal. Depending on your model year, you may be able to determine whether the other two vents are properly attached by directing a flashlight in the position where said hose attach.

I'm voting for the air-box drain hose.

If it's the airbox drain (pretty big hose 1/2" or so), then it would have been oil that leaked out. If it's the battery vent (about 1/8" or so) then it would have been battery acid, and you probally have corrosion under the battery. The fuel overflow drain is also about 1/2" but unless you just topped off your tank and then parked in bright sunlight, idoubt anything would leak when parked.

Gas will come out of the air-box drain too... LOTS of gas if you flood it. Don't ask how I know that...

thanks for you thoughts. From your responses I believe it is the airbox drain hose due to the fact that the hose is pretty wide. And what leaked out was engine oil.

The next question - by not having this hose attached, what harm would/could this have on my bike? This is on the assumption that the hose had been unattached for a period of time before I was aware of it.

The airbox drain hose is for draining stuff (that's not air) from the airbox. It's like your bike's urethra, it lets undesirable fluids out. So everything's fine.

Dirty oil/gas/junk would drip on your engine...

That's about it.

I thought he meant the open end... which isn't supposed to be attached to anything.

RVertigo · September 28, 2006, 02:36:13 PM

The L shaped end is open... The other end is kinda open... It has that little boot on it... At least it does on my '01.

Chuck · September 28, 2006, 02:38:45 PM

Is that the one you have to squeeze for it to vent the fluids? That's cool, because then it doesn't just spooge wherever it feels like. But I imagine no one ever does it and it just backs up into the airbox.

RVertigo · September 28, 2006, 02:43:31 PM

It will drain on it's own... Slowly. But, if you pinch it, it'll come rushing out...

It's kinda scary when it's a whole bunch of gas.

You should make sure that the hose is attached to the airbox and there is a plug on the end of it. You could remove the hose if you want, but you should plug the hole in the airbox. If the hole isn't plugged, it allows unfiltered air into the engine which could cause rapid wear, especially if the air is dusty.

Road construction dust seems to be the worst, theres lots of that going on arround my place and when I wash out my foam filter every 3000 miles it's amazing how much crap the filter catches. With that hole open, you're sucking a good portion of that through your engine. Not good.

It only takes a few seconds to see if it's the airbox hose, just check it out and hook it up.
Good luck
