I HAVE A SUZUKI GSF650 BANDIT K6 PROBLEM, I'VE REMOVED THE FUEL TANK , AND WHEN I RE- ASSEMBLE IT IT SEEMS I MISS PLACED THE UNDER TABK WIRES , AND THE BIKE IS NOT WORKING !

Hello, bike not running off of choke is an indication that the pilot circuit in the carbs is plugged.. the choke is a enriching circuit hence why it runs only with the choke on. When turned off the bike starves for fuel and dies. My guess is the bike has sat for longer than 4 months and the pilot jets are plugged from varnish... they will need to be removed and properly cleaned.

your cdi should be under the tank

- Take the seat off.
- Unscrew the two bolts holding the back of the tank.
- Remove (unscrew) the petcock handle.
- Lift the back of the tank. I'm not sure the air filter can be accessed without removing the whole tank. If you have to remove it, it just slides back and up - there are no screws in the front of the tank. Pay attention not to disconnect the hoses/wires if you are just lifting the tank, or disconnect them all if you have to take the tank off.
- Unscrew and remove the battery cover if necessary.
- Unscrew the airbox cover (two screws in top corners).
- Pull the airbox cover back and remove it. It's held at the lower end by two plastic "teeth" - no screws.
- Remove the old filter and put in the new one.
- Put everything back in reverse order.

Refer to the microfiche above for parts layout. This is a simple procedure that shouldn't take more than 30 minutes even with tank removal.

One hose will go to a vacuum source and the other to the fuel tap. The idea is that fuel will not run until the diaphram in the back of the Petcock is pulled back by vacuum. Prime the engine first and then swap over when the engine fires up.

Hope this helps.

Remove gas lines put tank on off. Pull seat. Should be bolts to hold tank. Pull tank toward rear and ligt. You might want to drain gas first
