Airbox tips? Where to start?

[Guest]

So I've heard the horror stories of the airbox and I know Chef and Ray would say RIP IT OUT and put pods! But since I'm not quite ready to rejet (whatever that entails) I am stuck with it for now.

But how to remove it? I have no idea. We're talking about Tom_MLC's 80GS1100E, and I'm going to need to get in there to a) sync the carbs and b) replace the fuel line which is way too short (he had a fuel filter which leaked RenoBruce removed and solved).

So is there a how-to for this thing, do's and don'ts, tips and tricks?

Please advise.

Thank you again, so, much.

why would you need to remove the air box to synch the carbs? also can you not replace the fuel line with the box in place?

[littleroot]

Really? OK, well, I just remember seeing the fuel line disappear into a dark area just before the airbox and I thought all the line connections for sync were on the rear side.

i wasn't saying, i was asking as well..i wouldn't think removing the airbox is nessecary to synch the carbs. the vacuum ports are on the inlet stubs and adjusters should be accessible.
maybe the fuel hose, it might be a bit fiddly but i reckon you could do it without removing the air box.....i maybe wrong of course.

OK, no worries. I will try to get a picture up tonight

Hi Bob,

You definitely do not want to remove the airbox to sync the carbs. It's difficult but I can get to the fuel inlet on my carbs to replace the fuel line, between the #2 and #3 carbs, without removing the airbox. I imagine it's a little tighter on the GS1100 but take off the tank and seat to see what's necessary. Go from there.


Thank you for your indulgence,

OK, will do!

Thanks

You can get a new fuel hose on there with everything in situ (except the tank and seat). If you give the new hose a little wipe with silicon spray on the inside it will help it slide on at the carbs more easily.

It will be hassle prone at best, especially if there's a hose clamp on it.
It will take a very long set of needle nose pliers to open the clamp if it doesn't have the screw type. Problem is the location, it's down in the "hole" behind and below one of the mounting brackets.
Once it's off though, getting a new one on shouldn't be that hard if you use something (a wire coat hanger) to guide the new one over the nipple, but then you got to get that clamp on there. Should be fun.

Hate to do it so I will probably leave as is... Or go through the hassle of removing the air box, which i am still not sure how to do

It has to run to syinc the carbs. I don't think you can do it with the airbox off.

In order to remove the air box you first need to remove the carbs. And if you remove the carbs it is easy to replace the fuel line. So just remove the carbs and replace the fuel line then replace the carbs. Leave the air box in place and you won't have to rejet. It is a tight squeeze to get the carbs in and out, really a PIA but everyone one here with that bike that does there own maintenance has done it. So that myth bust's the theory that it is impossible . And No you can not get a good sync. on the carbs with out the airbox , or pods and a jet kit, as the bike will not run in those conditions. In order to get a sync. it has to run. Good Luck

If your fuel line is just too short but otherwise good, you could just put a feed through barbed nipple in line (splice) with another section of fuel line to the petcock. The only way I would think you'd be able to change out that fuel line otherwise would be to remove the carbs. You can get these in different sizes at your local Ace Hardware store. I would use the largest size that would fit.

I wondered about this - worried it was Mickey Mouse but if they are proven I am game. Thanks!

So the process is first remove the boots, the loosen the air box clamps, scoot the carbs forward just enough to get to the fuel line?

Thanks
