I recently bought a 2001 VS 800 Intruder, low mileage, appears to be in top shape. The bike had been stored for over a year, and previous owner apparently had dealership service it and get it ready to ride. Hard to start when cold: it starts immediately but dies several times before finally stays running, won't start at all with throttle advanced. Doesn't seem to matter if choke knob is pulled or not. I verified that the choke cable is working and choke plunger is moving. Any suggestions before I remove the carbs to look for obstructed passages?

Re: Suspected problem with choke.
Hey apparently and did are two different stories draining the float bowls and cleaning the carbs are two different things the fact that the choke dosent change suggest the carbs are stopped up after sitting for 1 year clean the carbs let them soak in carb cleaner and blow them out with high pressure air, keep notes of the adjustments befor you dissasemble them (air screws)

You have an enrichener not a choke on your intruder. Most bikes are set up very lean so when you enrichen or increase fuel they run better. Has your bike been stored for a long time? Your jets could be partially clogged.. pour a qualty fuel cleaner in your tank like Lucas, Berrymans, or Techroline by Chevron. Also if you have modified your air cleaners you will run lean and need to re-jet..
If you let the bike sit and idle for about ten minutes and the cooling fan doesn't come on, it usually means your radiator fluid is low. The sensor to turn on the fan sits at the top of the radiator. So if it doesn't come on after the bike gets up to heat (this can take a LONG time in cold weather), you need to flush your radiator. Intruder Alert Suzuki Intruder and Boulevard Owners Club
Once a bike sets for a year the fuel breaks down a little and dirt and silt settle out of it and create this nasty sludge that will completely clog your carbs. The choke creates an area of low pressure
inside the throat of the carburetor that helps to pull additional
fuel through the jets and such. When you turn the choke off your fuel flow is once again restricted by your clogged jets that it cant get enough to run. Your going to have to pull your carb and go through it with pipe cleaners and B12 break cleaner. Hope it helps.
Nothing. Your best bet is to give to a professional. If you are somewhat mechanically inclined, you can tackle the job yourself. If you can get past dismounting the carburetors while remembering how it is installed into the bike (I recommend taking pictures), then you are more than capable of cleaning the carbs yourself. Let me know if you need any help with that. A service manual can be very helpful during this and other repair jobs. Remember, riding your bike is more fun after you fix something yourself.
Pull the tank and unscrew the fuel petcock to look at the screens on the fuel intakes. If there is crud on the screen it might not feed after a certain level (75 miles) and runs ok when feeding from the Res intake. Easy job don't be afraid to tackle it. Easier if the tank is near empty to begin with.
