Air box displacement

All right, I've had it with the airbox arrangement on the 83 1100 I'm refurbishing. The battery is located under the air filter box. To check the water in the battery, the carbs have to be removed, then the carb air box, then the filter airbox moves forward and out, and you can finally see the battery. That is absurd!

I'm going to mold a fiberglass air filter box that can be removed straight up and out without messing with the carbs.

Intend to retain the volume and characteristics of the original, which is a very odd shape. The best idea so far for matching volume is to remove and fill the old box with water, then measure the amount of water it holds and convert fluid ounces to cubic inches.

Is there a better way? Anyone?

Re: Air box displacement

Joe, some people like pods and think they are great. I'm not one of them. :-) I wouldnt put pods on a bike if you volunteered to buy them, install them and rejet and test the bike for free. :-)

My thought exactly! Aren't the first generation 750s sooo much easier? Actually, you don't have to remove the carbs. Remove the seat, remove the bracket that the tank and seat fasten to. If you're a real sadist, you can leave the tank on, but you'll have to raise the rear of it up. I just didn't want to deal with gas lines and the gas gauge wire when I did it. The airbox will come out with some fancy twisting and foul language. :evil: Uh, why would you want to check the battery water anyway, isn't that what that light is for on the dash? :lol:
 
Battery

Battery

Earl I thought you used sealed batterys so theres no water to check!!! But I was going to say fill it with water but you already came up with that. Iam lucky pull seat undo one clamp at air box and slip filter box out 3 mins. tops
 
Re: Battery

Re: Battery

I usually do use sealed batteries. I do have a perfectly good "water" battery and it seemed kind of silly to just toss it. Besides, even if I did buy another sealed battery, getting the carbs out with the airbox jammed into them is a nightmare. It would be sooooo much easier to remove carbs if I could take the airbox out from the top.

I wish the filter box would slip out of this one, but the only way that is going to happen is with about a 3 ft crowbar. :-)

box

Earl I just went to bike bandit and the set up looks the same as mine, air box stays on the carbs and the snokel to the air filter pulls out thru top, and holds the battery down??? what am I missing here??? I hate to waste a battery also!! Im not trying to be stupid Iam just curious
 
Re: Air box displacement

On my 750, to check the battery, all you had to do was unlock the seat and raise it. :-) To remove the tank, airbox, fuel line, choke, throttle cable and carbs was under five minutes with time for a cup of coffee and a sandwich. :-)

Earl,

I knew you weren't a fan of pods so I was curious what your response would be. :lol: I love the pods on my 1100. They make carb removal so easy I almost don't mind removing them. I think I paid $55 for the K&N pods some years ago. Jetting wasn't too bad either. I bought a K&N (Dynojet) kit when they were on sale for $40. Installation and setup weren't bad either. I had to pull the carbs a few times to get everything adjusted correctly and haven't had to touch it since. Once I got it all set up my bike starts, idles, and runs better than ever. I was expecting some performance improvement but the amount of improvement surprised me. Of course, I am mostly a fair weather rider so rain isn't much of an issue but I have been caught in rain quite a few times and have never had a problem. So for under $100 I got a significant performance improvement, made maintenance noticeably simpler, and gave the bike a nice high-perf look, with no negative side effects.

To each his own and I understand your point of view but the only way the stock airbox will go back into my bike is if and when I decide to return it to original condition.

Joe
 
Re: Air box displacement

I agree with you. To each his own. Out of curiosity, do you remember your original gas milage and do you know what it is now with the pods?
Do you have a stock exhaust or aftermarket and if so, what kind?

Earl,

Gas mileage definitely went down with the jet kit. I don't compute it exactly but I would say it went down from low 40's to high 30's. Of course, that depends on how I'm riding. I don't think highway mileage went down as much as sport riding mileage. Spirited riding probably brings the mileage down into the low-to-mid 30's. Obviously it takes fuel to make power. My bike has a Supertrapp Stainless 4-into-1 system with tunable flow discs. I currently run ten discs which gives a nice throaty sound without being obnoxious. Here's a pic that shows both the exhaust and the pods:

By the way, another cool thing about pods is the intake roar you get when you crank the throttle. At low speeds the intake honk is more noticeable than the exhaust.

Hey all,
I had the same thought on my 83 1100E. What I ended up doing was removing the stock airbox, and leaving the plenum to the carbs. I then found a medium size cone filter ( I used a "AIC" "clearview" cone $23.00 at pep boys. removed the plastic cover and trimmed the flange. Now that I know that it will work, I will orde an appropriately sized K&N when finances allow) And used a 3" long rubber mounting adapter( home depot plumbing dept. $3.00) to mount the filter to the plenum inlet. It made sense: get better airflow, keep relatively non turbulent air at teh carb mouths ( one of the reasons for using a longer adapter)
It seems to run better, better throttle response. And not real apearence chnge once the side covers are back on.
If anyone is interested, I will go out nd get a picture to post.

later,
Derrick
 
Yessir Derrick, I would be interested in seeing what you have done. For sure, I am going to do something about the access problem and the frustration of fighting the lack of space.

Re: Air box displacement

Thats a REALLY NICE looking Teddy Bear ya got there Joe. :-) Same year and model as the one I'm working on. Although, mine looks nothing like that at the moment. Although, if I took all the parts out of various boxes and stacked them in the correct relationship to each other, hmmmm, come to think of it, it still wouldnt look like that. LOL

I know what you mean about intake noise. My old H-1 was the loudest bike I have had for intake noise. Sounded like an 80 hp vacuum cleaner when I wicked the throttle. LOL The thing would suck ankle socks up to my knees, it grabbed so much air. :-)

My overall fuel mileage dropped about 3 mpg. Like Joe said, more power takes more fuel.
I recommend pods. As long as they're K&N's with a good pipe and you have the patience to re-jet correctly.
C'mon Earl, pod and pipe that puppy! :)
 
Only in your dreams Keith. :-) I have been looking around to see whats available in small used helicopter turbines though. :-)

I cant seem to get the direct posting to work, i probably just need a different server.

thanks and happy new year,

I dont own an 83 1100, but on my 82 Katana the battery is also under the air filter housing, and I only have to remove it to check it, two screws and one clamp, a little swearing and it is out, I also went seaching for a single pod to replace the filter housing, you need a pod to fit a 2 and a half inch hole in the rear of the plenum, I must admit that a single pod is my prefered way of doing it, it is more stealthy :wink: I like it to look as close to stock as possible to keep that surprised look on poeples faces as I blow past. I have not had an opportunity to run it enough to re-jet yet , but I will keep you informed.
Dink
 
the way that I did it was to use a 2.5 inch diameter rubber plumbing adapter to fit over the plenum mouth, the the cone filter mouth fits over the outside diameter of the rubber adapter.

Re: airbox mod pics

Re: airbox mod pics

Thanks, when I get everything back together, I'll set it up like that and see what I get for a plug burn and throttle response. I can always make a airbox that will lift straight up and out if need be.
