Okay, so I've checked the Clymer's and the Owner's manuals, and neither of them can tell me where the vent tube that dangles below the bike hooks up to. It's become disconnected and I can't, for the life of me, figure out where the heck this thing plugs back into! I'm thinking the back of the air box behind the carbs, but can't see it too well. I plan on ripping out the carbs tonite and thought I'd try and put this thing back where it's supposed to go while I'm at it.

Thanks

depending on your bike, there should be at least 2 of the hoses dangling down (some have an extra one for the battery). One is connected to the left side of the breather box, on the bottom (theres a nib there for it) and the other should connect to the......um.......not quite sure.
 
Re: Simple question

Most likely, the tube came off the plastic vent on the side of your battery. Its to keep acid off the frame.

I can trace the battery breather down to where it ends. It's an 81 1100E. If any one has a Clymer manual, you can see the tube on the front picture. I'm tending towards the air box because the tube has about a 90 degree bend at the top.

Thanks again

Brad tt
 
90 deg bend eh? Yup, thats the airbox. I never bother to put a drain tube on the airbox. there should not be any fluid draining from the airbox. Its an Airbox. LOL

LMAO :lol: :lol: I'm not really too concerned about it, but it's been driving me batty that I couldn't tell where it went to. And, not to mention, that I couldn't find any mention of it in either manuals! It's started to drag on the ground and I figured I better make sure it's not important before I discover it gone.

Brad tt
 
Brad, if its dragging on the ground, you could always fold it and put a rubber band around it. LOL

It's on the airbox for two reasons.
Fuel can overflow into the carb throats and drain into the airbox. The hose routes the spill to the ground.
The other reason is discharge from the crankcase breather tube drains into the airbox too.
So put it back on and stop yukking it up funny boys! :lol:
 
Seriously Keith. If I have fuel draining out of the airbox vent, I have a much bigger problem than a little mess on the frame underneath. The same is true of oil. If I have enough oil vapor blowby to condense and result in oil dripping from the airbox, there is a problem. I dont use a a tube on the airbox. There aint no oil or gas mess underneath it either. :-)

The last time I had the airbox removed, there was not the slightest bit of oil residue in it.

Additionally, the location of that tube would result in (if it were present) gas and oil draining onto the tire. Not exactly a desirable situation.

I would like to add that I have been cought in rain hard enough that it got sucked into my stock air box!!!!
but then again, where water drains to out of the air box is not a issue as long as it does drain out of the air box.
 
Earl, I'm just saying why the hose is there. It has a purpose.
If you WERE to have a problem, the gas flowing out the hose would be the lesser of two evils. The factory designed it with safety in mind and to keep your bike cleaner, not me.
The bikes I've seen have the hose routed off to the left or right of the tire.
You can always re-route it and get a longer hose if you wish.
The hose exists for the same reason we have carb bowl overflow hoses, to keep fuel off the possibly hot motor and/or electrical parts.
As for crankcase breather discharge, you may not see any in your airbox, but I've seen it a lot. Many times it never gets to the point of actually going out the hose. It can come out as a thin film that's kind of sticky and just keeps building on itself. It can coat quite a large area inside the box.
No design is perfect, but I think we're better off with the hose on.
As always, you know I'm not arguing about this, so don't take these words like that. :) I just thought I should mention why the factory installs those hoses.
 
I could have swore that there was a vent line from the tank that went down there also...

Yes there is. At least there is on my '83 1100E. I can't help with the airbox question. All I know is that there is no drain hose coming from my pods. :lol:

Does this mean that you guys that know what they are for are a "bunch of hosers"? That's a midwest expression, BTW......

And yeah - condensation builds up in airboxes.

Condensation occurs when air pressure drops, like in tailpipes and especially the high performance GS's that Earl and Keith are running.

Last time Earl twisted his throttle wide open to blow by that truck on the S curve, I could hear the huge sucking sound all the way up here in Wisconsin! That must have produced some condensation. ....and no, I don't mean condescension!!! - Dieter
 
I'm not arguing Keith. I was just saying why I dont use the hose. I dont have overflow tubes on my float bowls either. But then, my float needles dont leak or stick and the Pingle petcock is OFF when it is off. :-) :-) :-)

@#$^%#@!!!!! :x Well, it is NOT the tube from the airbox. That one is like a half inch in diameter, while the other one is probably around 1/4". I got the airbox off and there is only one tube hooked up there. I'm not sure what this other one is for at all!! I can't find any other hook ups on either the airbox or the filter box. It seems to have oil around the top of it. I know it's not from the tank because all those lines came off with the tank. (Which, coincidentally, I found that an in line fuel filter had been put on the "prime" line!) I don't think it's from the carbs because I don't see any hook ups there! It seems this isn't so simple!

Make sure you really have all the hoses attached to the tank, theres one that can hide on you that runs under the tank along the frame and connects near the front on the bottom. Then there's the fuel guage sending unit one. Other then that you have 2 vent lines coming from the carbs, that should route up over the airbox. I thing that's it though.
 
hi
I have 5 hose that dangles below the bike

1 from tank fuel drain

2 from carb.

1 airbox

1 from battery

2 from carb.I left those two on the carbs

1 airboxthat one is a larger diameter, and it, too, came out with the airbox

1 from batterythat one is still connected to the battery and it's a clear tube. The one I'm referring to is black

I'll have to get a picture of it before I removed the carbs, and one of the it without

Brad tt

Oh yeah, it also has it's own bracket holding onto the frame. I'll get a pic of it.
