Simple question

[earlfor]

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. :-) :-) :-)

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.

@#$^%#@!!!!! :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

hi

1 from tank fuel drainI'll have to double check that one, but I do remember pulling that line out without disconnecting it from the tank

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.

There are only two hose connections on the airbox. One is 1/2" inside diameter and located on the top forward face of the airbox. It goes to the breather on the valve cover. The other is 1/4" diameter, and may have a 90 deg bend to fit onto the airbox fitting which is located on the bottom center of the airbox or on the lower rear face.

If the hose is 1/4", it is not a float bowl ventt tube. Those are 3/16" Fuel is 5/16" Only vacuum hoses are 1/4" line. It may be the hose for the carb#1 to carb #4 vacuum balance. Frequently, carb #2 does not have an external vacuum nipple. #2 balances internally with #1. Vacuum from #1 is "jumped" via external nipple on #1 to carb #4. #3 draws internally from #4. The nipple on #3 operates the vacuum petcock.

(there are/can be other vacuum tube arrangements on different GS models)

D'oh, I forgot to say the airbox had two hoses, breather from the engine, and the drain from the bottom. The bottom one is a 1/2" hose with a tapered end (gets larger in diameter) that fits onto the air box.

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.

Earl

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!

umm...... so if you do have some stuff in there, what would it be from? Im taking apart my carbs this winter, and was hoping that would do it.....

[earlfor]

If its gas, that has to be coming from the carbs, so would be from either the petcock or the float needle valves. Oil, I think the highest probability would be valve guides, but unless it is enough to be draining fluid from the bottom of the airbox, I wouldnt worry about it. I would be sure to route the airbox drain hose away from the rear tire.

Earl

Earl, Earl, Earl. What am I gonna do with you? :roll:
You took off the bowl overflow hoses too? I know your carbs aren't leaking. Neither are mine. Anyone's bike can get a leaking float valve. The hoses are there to drain the gas from a hot motor IN CASE something happens.
You wouldn't remove the spill hose for the fuel gauge sending unit, just because the unit was not leaking.
You wouldn't eliminate fuse protection just because you havn't had any shorts or grounds. It's a safety issue.

[earlfor]

A leaking float valve? It wouldnt dare. :-) :-) :-)

Gentlemen Gentlemen,,

We all need to understand that where our hoses go is a concern to most people. As explained, a misplaced hose can be as harmfull as not knowing where our hoses have gone.

But for some, they prefer to be without their hoses all together and they have that right. So, to hose or not to hose, that really is the question here and the answer lies in the hearts of the individual hoser.

[earlfor]

ROTFLMAO :-) :-)

insert key, start bike, enjoy.

Worry about the tubes if it does not run
