Air box displacement

[earlfor]

Only in your dreams Keith. :-) I have been looking around to see whats available in small used helicopter turbines though. :-)

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!

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 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.

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.

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.

Yep, I think trying to make it liek the earlier GSs would be the easiest way. Doesn't Hap run a single pod with the airbox in place.

BTW Keith, I have improved fuel economy since I did the bike up years ago. Always got around 50mpg, now get 60 or so in the same conditions. More power made more efficiently I think. I must have paid for the extra engine mods by now in gas savings alone

Re: Air box displacement

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. Uh, why would you want to check the battery water anyway, isn't that what that light is for on the dash?

'83 to '85 GS750/700 is even easier:

1) Unlock and lift off seat.

2) There's the battery!

Well Simon, I understand you perfectly except for step 1 and step 2.
Its sooooooooooooo complicated.

I've never heard of a 1000 getting that kind of mileage with a mix of driving conditions. Not even if the miles were all highway. Years ago I helped a friend jet a '79 1000. It was my first experience with jet kits. He installed a "Factory" jet kit. He simply set up the carbs to the recommended settings in their instructions and considered it re-jetted. It ran "OK". He commented how the mileage went from about 40, up to about 45. After several hundred miles, it became apparent the jetting was not right. He was getting some light pinging up hills, etc. We pulled the plugs and they were snow white.
I remember how he was happy about the better gas mileage, and we talked about the "efficiency" of a more powerful motor. It kind of made sense that a motor that made more power would not need the throttle opened as much and maybe that was why he got the better mileage. We both had read how drag racers run leaner mixtures and the motors run strong. I was not convinced and I told him I think to maintain the correct fuel/air ratio, the motor must use more fuel to match the increase in air intake, at least on a motor you want to last a long time. I've since noticed that lean running motors can fool you with their strong performance.
Anyway, the plug reads proved his motor was way too lean. We both played with the jetting and he was amazed at how much better the bike ran, because he thought it couldn't run any better. His gas mileage did go down similar to most of my other experiences. Usually a few mpg,
sometimes up to 5 mpg less.
I suppose there can always be exceptions under ideal conditions, but I would like to read your plugs after a few miles at 90 mph. I can't see a correctly re-jetted 1000 getting 60 mpg in the described conditions. Not with pods and a pipe. Not even a stocker. Just my experience.

Of course, Earl, I forgot step 0:

That explains it, everything is bigger is OZ. In US gallons, he is getting about 3 mpg. LOL

No, no, no, Earl!..........he's also using Imperial Miles........each of which is equivalent to 5/12ths of an Imperial League!

(I could specify that in rods, poles and perches, if that would help )
