So here is the back story...

http://www.thegsresources.com/_forum/showthread.php?t=221162

1980 GS550E

Basically i have a great set of VM carbs and boots but the bike is supposed to have CV carbs. I want to ask if anyone knows of a way to make them work instead of getting a whole new set of carbs and boots...

are there any adapters i can buy? (long shot i know) or more likely, some sort of adapter i can make or someone can make for me?

thanks in advance everyone, the bike has a few other issues and Im worried i just bought a Lemon... :mad::mad::mad:



 
I have only known of adapters back in the day that allowed you to adapt VM carbs to CV intake manifolds. Never knew of anything going the other way though. may have to pony up for some CV intakes. And whats up with that washer on the one flange???
 
the P.O. ghetto rigged the carb setup. the rest of the bike isnt too bad but all of the intake boots have fender washers on them because they are too small. i dont care about aesthetics i just want them to work right...

Even if i got new intake boots for the correct CV carbs, the wrong VM carbs that i have wouldnt match up with the boots. So i would have to either make an adapter or get a whole new set of CV carbs and probably have to rebuild them... I'm really wanting to use the ones i have.. both the boots and carbs are in great shape so i hate to get rid of them.

wait! i just re-read and caught what you said and thats exactly what i need! i HAVE VM carbs... but they should be CV's so if there are adapters that allow the VM's to go onto the CV intake manifold thats perfect!

Chuck, he is not going the other way. He wants to do what I highlighted.
 
Does anyone know if the intake boots for my 1980 550E would be the same as intake boots on a 850 or 1100? or are all the boots different sizes? because if so, i may have an adapter idea...
 
No, they are not the same.

Not sure about the port size on the head, but the '79 and older 550s had VM carbs.

What size VMs do you have?

I'm not sure, how can you identify them?
