lugnut1009 I've thought a lot about this modification. What size PVC did you use? 1 1/2"? The design I had in my head was copper pipe fittings, 1 T and 1 90 with maybe a 45 on the outside going into the carb... I'm definitely interested in the outcome. Might go this route with my 85 when I get this far with it.

Juice Thanks for all the info guys but I'm using a mikuni slab carb 38mm and it's off an old drag bike so the jets are huge so need to change em. I'm going to go off the sizes that the vn800 used and go from there will keep you posted. Here's a pic the poly pipe is only tempary while I have the stainless manifold knocked up.

Knifemaker I believe the Vulcan 800 used a single carb. (CVK 36) Perhaps you can research that and go from there?

chokingvictim im in the same boat running the factory rear solo, some say stock jetting works some say you gotta up jet 20+ sizes..if you take the plunge please report back with your findings! I'm sure a good few will be thankful someone put in the footwork to find out.

michiganteddybear would like to see some pictures of your setup..

as said, there is NO off the shelf setup for single carb

the number of carbs shouldnt affect the jet sizes, as long as the carb is properly sized for the demand of the engine. I would say the same size as stock would be a starting point

Thorn I'm not sure there even ARE any pre-existing single-carb setups currently running around here.

ARRRRR need single carb help

So I've tried and tried with the original carbs and they have now been drop kicked across the field lol. I've got a single manifold built and a nice slab carb on it but need to know what size jets you single carbers are using?
