SOURCE: my 1400 intruder pops and back fires

I think maddogcycle is right. One cylinder is running rich and the other running lean. It seems as though they have not been balanced properly and the mixture not accurately adjusted. The settings on these carburettors are critical and must be adjusted with the proper gauges. I'd advise you to have the carbs cleaned and adjusted and tuned to the engine for balance of inducted air flow and fuel/air ratio (mixture)

Testimonial: "Thank's guys.I have taken it to a dealer for service and passed on your thoughts to them.Great job."

93 suzukie intruder dies after driving for a few minutes after it sits for about five mins it cranks right up. night before that happened seemed like the front head quit firing as i was coasting to a stop....

Ensure your choke cable is retracting properly. I had that on an old Honda and tried everything till I spotted the cable getting trapped under the tank. Look at the top of the carbs and wiggle the choke. If its sticking use something like Castrol LM grease or Coppa Slip as these last longer than WD40 releasing oil.

My suzuki intruder is missing backfiring on the

Did you sync the two carbs? If not the rear may be getting all the gas from the rear carb and none to the front. Twist throttle engine off and see if front carb cable is pulling the carb open.
Also unscrew the spark plug boot from the front spark plug wire and trim 1/8th inch off the wire and screw the boot back in. The plug wire end may be corroded on that wire.

Suzuki vs800 intruder dies after about a mile!

Sounds like water in the gas. ALWAYS have a fire extinguisher on hand when working on carburetors.
For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb.
Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
