Airbox?

I have an 82' GS750E, and it currently has some super crappy and cheap pods on it. I doubt it has been re-jetted, and I'm not sure if I want to deal with getting expensive pods and trying to get mixtures and jetting correct. But how do I know what airbox's fit my bike? eBay has some but I don't know what fits/is interchangeable. Would it be cheaper/easier to get a used airbox and filter for it, or just get new, good quality (APE or K&N) pods? Thanks all.
 
Easiest way is to go through all the fiches of similar bikes and compare part numbers. The 2nd gen GS750E ran from 1980 to 1982 and the GS1100E was 1980-1981, I believe.

Going back to the stock setup might not be cheaper, but it will always be easier because then you're back to a known quantity. A baseline, if you will. Whether to mess with pods and jetting is completely up to you. Some people have good luck getting everything adjusted properly, but it can be tedious even for experienced tuners.
 
What is your consideration of "super crappy and cheap" pods? Only asking because I bought pods, and not K&N ones.. Hoping theses aren't the ones I got..
 
The 1980,81,82 750s use the same air box, as well as the 80 and 81 GS1100E. Your air box is a two piece combination. One houses the filter and connects to the box that the carbs connect too. All have rubber boots. If those boots are hard and cracked, you'll have to order all new boots and clamps. Check the boots from the carbs to the head as well. All those rubber connections have to be sealed for the bike to run properly. You are probably asking me why new clamps. Here is why, the old clamps loose their tension, I know, I was surprised when I replaced all mine when I did my carb rebuild, 34 year old clamps, just ain't gonna work. Oh yeah and they need to be the OEM clamps, they have to fit the groves that are in the rubber boots. Regular hoses clamps are too big and won't let the boots seal up properly.

My engine side intake boots look very new, and are not cracked or hard. The clamps seemed fine too, but it's the pods that suck. I just don't know if I should go to an airbox or not :/
 
I cannot answer that question for you.
I do not know how difficult it is to remove or replace the airbox on your bike, or what is involved in it.
Could someone chime in on that?
May make it easier for him to come to a decision.

Air box, it's not easy though once you have done it a couple times, you know the routine. I can take my carbs off in about 30 minutes. Takes a bit longer getting them on, gotta make sure the boots are aligned right for the most part.

The way I do it is: pull the airfilter canister off, then unbolt the air box from the frame, loosen the clamps from the (don't loosen the front clamps yet) back of the carbs, slip off the box and push it back. Now loosen the clamps on the front (leave the clamps tight on the head side) of the carb, make sure your throttle and choke cables are taken off then pull the carbs back and they should just slide off the boots. Remove the boots then.

Reinstall, start with the middle boots first, get the carbs started into those then add the outside boots, leave loose for now. Now slide the air box boots on to the carbs, make sure the center ones are in, seems like the #2 boot is a bit onery at times getting it to seat right. Now smug down the rear clamps make sure they are in their groves, on the front boots, turn them until they are aligned with the carb and head and tighten the clamps, those too need to be in their grooves. Reattach the throttle and choke cables and adjust, go back over and check and make all the boots are seated and aligned and one last tighten of the clamps. Reattach the filter housing and the air box back to the frame. A little slippery stuff rubbed inside the boots will help with the install.
