Airbox question

[jwebfournow]

Hello to all!

I have a question regarding the airbox on my 1982 Gs1100gk. I'm doing the sealing project on this box and I'm wondering if there is supposed to be a snorkel on the backside or is there supposed to be just a plain opening there. Thanks for any insight.

Hi,

I thought all of the shafties had a snorkel on the airbox. It looks like this one does, but it's not a good angle.

Is your opening in the back on the bottom of the airbox? Here is what mine looks like.

If you do have a large opening in the back on the bottom of your airbox, chances are the snorkel has been broken off.


Thank you for your indulgence,

BassCliff

I have seen the back of the airbox on a couple of GKs, yes, there should be a snorkel. :-\\\

Yes, that is correct. Just finished a restore on my 1100gk2. What I have found is that it is a pretty tight fit with the snorkel on to reinstall the carbs. So, your PO probably took it off to make the install much easier.

This is what one looks like out of the box.

Thanks a bunch guys. I thought there was supposed to be one,do you think not having one would have an effect on the carbs, I'm thinking I have a lean condition going on. And does anyone know were I can get one. You guys are great I have learned so much information on these bikes from the help recieved.

Just removing the snorkle wont matter as long as the rest of the airbox is there with a stock air filter, not a K&N

Well actually it does have a foam style K&N what do you think, are the originals paper? I did see k and n on the side its the tytpe you put some oil on

When I got my 1000 it was also missing the snorkel. The result for me was a monster flat spot. Once I got another snorkel and installed it problem solved. I think a lot of them get removed in the search for "more power" but the result is really a lean carb condition and the flat spot. You can try to cover part of the snorkel opening with duct tape as a temp fix but really should find a replacement IHMO. These bikes need the correct airflow to run properly.

The OEM is a foam filter, the K & N replacement (SU-1200) is a cotton gauze type filter. Usally E-bay is the easiest place to find a replacement airbox. I am pretty sure the G & L airboxes would both fit your bike as long as they look the same from the outside. Heres one that should fit at a pretty good price. Looks like it was taken off the sellers other airbox item for sale.

This filter is definetly all foam, and yes it seems to have a flat spot also. air mixture screws set at 3 1/2 out, when fired up cold it pops a little then after a few minutes get better. This bike starts on 3/4 choke after about two minutes when I crack the throttle it wants to bog I figure its still cold, after its really warmed up I can crack the throttle its alot better but still has a little flat spot, if I take it up too about 4k feels like it wants to surge some. This is what I have done so far.

1. took carbs apart dipped each one, new o-rings,throughout, including intakes, intakes all looked good and had been replaced by p/o.

2. New stator

3. Adjusted valves

4. New plugs

5. Sync carbs
