Single Carb Conversion for my 1976 GL1000
Does anyone have an Opinion or any Experience converting a '76 GL1000 to a Single Carburetor kit? Seems to me like it would starve of fuel but I'm unsure of how it would actually work....Thanks in advance

What happens when you bank a curve sharp for a while? Wouldn't fuel not be able to get to the opposite side? That's my only concern.... And Thank you for the links also.

"gravity" is always at the bottom of the bike.
Do you slide out of the seat while going through a twistie?
Centrifugal Force will keep the fuel in the carbs where it belongs.

The fuel charge is in an atomized state with the incoming air. The downward stroke of a piston creates a vacuum within the intake manifold pulling the charge into the cylinder.
If I follow your thinking,
how do the guys that do hill climbs in trucks ever make it to the top with 700hp to spare if the fuel was only getting to the two most rearward cylinders in a V8?
If I follow your thinking,

Ah I see what you're getting at
Thank you. I my '76 GL 1,000 runs okay now, just likes to get stuck at 3,000 RPM's for a while before it drops back down to 950 RPM's. I have it narrowed down to either the Air Cut-Off Valve, or 1 or 2 potentially bad floats I found when deep cleaning the carbs. I will get a Whole Carb rebuild kit soon, as I want to keep this bike original I decided, but I want to try to single carb conversion for my '82 GL 1,100. Any carbs besides VW that you think might also work?

The problem could be weak springs on the spark advance mechanism. You can fix this by taking about 1/2 loop off each spring.
