OleDirtyDoc unless you have an aftermarket petcock, fuel should not flow unless it's on prime,as these petcocks are vacuum operated.if you had a sticky float,you would still flood when idling, and bike wouldn't idle well

vulkan Oboy....forgot to turn Petcock off. So here we go (was told I had a sticking float) thought now be a bitch to start...could have a gas flooded piston chamber.Hit start button...started just fine!!Sooo....could be that fixing the choke cable "fixed" the hard start issue??Maybe no sticky float??

OK picked up the Vulcan Friday,they got that choke cable in there AND figured out "start" issue.Charged me $100 bucks....so I'm good!!(Start issue... float stick so it causes (1) cylinder to flood,chitty for starting!!They suggest I TURN OFF GAS every time I park bike...few minutes/few hours...don't matter.)

Hexadecimus I've podded and tuned more of these carbs than I care to remember and got them all running like champs. I second yanking the intake. You'll likely need to rejet a bit and/or shim the carbs even with stock exhaust. I've posted a rejetting calculator on this and other forums.

If it's running like crap, 95% of the time it's in the carbs, not a vacuum leak or anything else. Spray carb cleaner or something else flammable around the intake boots when it's running to check for leaks. Once it catches, you should be able to keep it running with a touch of throttle and no choke until it's warm. If not, you've got carb issues.

I'm sure you can get that choke cable on though. Loosen the handlebar adjuster, insert the bead on the carb end and then fit the metal L-bend into its bracket on the carbs. If you need to, you can disassemble the choke lever to pull the bead otu of that end for slack.

You CAN do the carbs single-handed but it's 10x easier with a helper to pry up on the plastic intake plenum while you insert/remove them. Give it a good hard pry, and it's almost as easy as on a "shaved" and podded bike. You don't even need to take off the plenum-to-carb boots. Just be sure you leave the front carb-to-head boot on the head, and the rear comes out with the carbs. And keep them aligned rotationally. There's a little nub of rubber that aligns with a nub of metal on the heads.

gidaeon Ive done this a few times, much easier after the first time. If you have stock air-box I highly suggest trashing it, earshaving and rejetting as needed accordingly.

Several of the posted pictures with labels were exactly what I needed to get mine right, but keep all the cables in stock position and length. no jerry rigging here.

YOU can do this - you'll be happier you saved money and know the bike better for it. are you confident your carbs are truly all in good order internally and linkage assembly. I learned there are a few mistakes you or another can make if you ever disassembled the rods and linkages.
