On the VL800, it is not a choke, but an enrichment circuit. If the bike will not idle without the knob pulled completely out either the idle speed is too low (it is supposed to idle at 1100rpm), the mix is too lean (either plugged jets or an incorrect air filter) or the air/fuel mix screw is not adjusted correctly. If the idle is good and you are running an OEM filter with no air leaks from the air box to the carb, then the issue will be with the carb, jets and fuel mix. On the outside, it could also be the screen in the bottom of the gas tank that could be plugged with rust or sludge from old gas.

I have an 04 and ran into this problem after a dose of seaform, had to clean the carb not once but twice cleared up and ran perfect after that.

The Seafoam cleaned well, wellmaybe too well think it knocked some boogers loose clogging the carb but have had good results with it otherwise.

Seafoam is an alcohol based solvent that was used in the marine industry to remove sludge caused by two-stroke oil in outboard engines. It has since been recommended as a cure-all mechanic in a bottle. Pouring a can of seafoam into a 5 gallon tank will cause issues as the alcohol will attack your hoses and seals while it sits. If you use it, use the RECOMMENDED amount. Will it work? Probably not. Mechanic in a bottle usually only separates you from your hard earned money.
