Starting Problem

Okay, was trying to get the Vulcan ready for the summer. I put the battery in and put on the choke and she just turned over and over with no start. I then tried without the choke on and the same. I then rocked it back and forth and then tried to start which she fired up but then shut down after a few seconds of running. She ran fine last summer prior to putting her away for the winter and used seafoam also. Any ideas on what could be wrong? I had the carbs cleaned last year also. She is a 2001 Vulcan 750 with 4500 miles.

Thanks
Bill

What type of battery? Did you keep the battery charged over the winter or charge it before putting it back in the bike? Did you make sure the cables were clean and attached securely?

How many times did you try to get it started?
When I finally got mine running earlier this year, it took a few tries, started then quit, then started and quit, but after some slightly rough runnin' it picked up and ran just fine.

Did ya check/clean the air filters? How do the plugs looks?

The battery is a maintenance free and was fully charged when placed in the Vulcan, it also has new filters and new plugs. I have put it on reserve but it only starts for a few seconds after twisting the throttle and rocking it and this was done about 50 times until the battery drained completly. It is driving me crazy. It ran great last year before I put it up for the summer.

Ya might do well with a tank that's at least 1/2 full (sounds like the tank is low?) I've found that sometimes my old girl gets grumpy when her tank is low and she's sat for a few days.

Might also be helpful to leave the gas cap open - sometimes a vacuum can be created that prevents the bike from getting the fuel it needs...

Well cleaning the carbs last year don't do you any good now...did you leave gas in them when you parked it for the winter?

Sounds like they are just gummed up. Fill them with carb cleaner, let them set awhile and then drain them using fresh gas (with a little seafoam)

90 percent of starting problems after "winter sleep" are caused by icky carbs...
(icky is a technical term of course)
