Does anybody have any experiance with the aftermarket carb conversion kits from 4 carbs to one?
Does the one VW carb do a good enough job to feed the four cylinders and provide enough HP and torqe?
What about fuel milage?

Ive only read about the results.
Solves the "touchy carb" issue.
Economy is about the same.
Some suffer from fuel starvation in a deep curve.The single carb was not designed to be tilted.
Poor fast throttle response due to the physical increase in distance from the throat of the Carb to the intake valve.
Some reports say it's good enough to live with,others not so much.
It's really hard to simulate 4 discrete carbs mounted 4" from the intake valves with one Carb mounted a foot away.It seems to take a lot of tweaking to get it to run good.
That's one of the reasons really snappy engines are direct injected.

Thanks Virgil, is there a kit to install fuel injection? I'm not much of a mechanic and I don't have the $ to keep sending the darn thing into the shop @ $85 / hr.

If you have a little mechanical ability you would be better working on the carbs yourself. There is a ton of information here on solving your own problems. If I had to pay someone to work on my bike it would probably be parted out on Ebay. Here in Wisconsin the local labor rate is $90/hr. The carbs are always the issue but when you get them right your bike will never run better. Just store the bike well over the winter and you won't need to worry much about the carbs. The BEST mechanic is you.

I agree about the DIY....It seems to always turn out better than a 'for hire' mechanic.
Not because of his abilities but your attention to details.
It just seems only a specialty shop has the intense interest to service for performance and usually command a high price for it.

I'm not aware of any plug and play EFI systems for retrofit on any wing.....I've read about one guy spending a bunch of money and time converting his 1500 carb to EFI.

It is really much better to keep the bike OEM if possible....When the carbs have been tended to properly,the ignition system is spot on,the gl1100 is a truly exhilarating machine to run.
The same for the other wings too.
I am not a mechanic by any stretch of the imagination but I did stay at a Holiday Inn once.... :mrgreen:

It really isn't difficult to maintain and tweak the bike...even with a limited space and tools.There's plenty of help here and most of us have been in your shoes...
I have restored and bench tested a gl1100 carb pack on the kitchen table once too....
Well...she wanted to ride and this was the only option.... :lol:

As far as money???? a can of brake cleaner,shop towels,a few tools,sand paper,Mothers aluminum polish,0000 steel wool...It really didn't amount to much...less than the minimum charge at the Honda shop.

Sounds good guys.
I'm going to give it a try this Sat. (take off the carbs and the float bowl then try cleening the jets.........See what happens) :ugeek:

One thing to keep in mind is you can never take enough pictures. Snap a pic for every step you take. It will be one of your greatest tools when you go to reassemble your project. Plus, if you get in a pickle, you can share the pic with the rest of us and help will be on the way! :D Good Luck!

Well, we took off the carb unit sucsessfuly (all four in one unit) then took off the float bowl on one and found the main jet, looked good and clean. You could see clear through all the little tiny holes. Soaked it in carb cleaner and sprayed carb cleaner down the hole. The problem we encountered was the "idle jets" we didn't see a way too get them out. They were way down in the hole and there was no slot on top of them for a screw driver. What did we do wrong (what don't we know that we should have)?

As I remember,the slow speed jets are just stuck in,not threaded...One fellow uses a sheet rock screw to grab them ....Search the method..."jet removal"...
Here's one entry...viewtopic.php?f=4&t=10132

Oh,get the slides moving absolutly butter smooth and use a shop vac to test them before you put them back on the bike....
