This is the only bike I have ever had and I do not know much more than tires, batteries, and oil. I could really use some help please. I have a 1999 Suzuki Bandit with 10k miles. I have owned it for 5 years and have put most the miles on it. Unfortunanely it sat for a year. It did not run correctly after i started riding it again. I had the oil changed, the bike tuned, rejetted, plus spark plugs changed by a shop. I am still having a problem though. When I am coming to a stop at a stop sign or red light my bike will do a lil sputter and then stall out. Or i can be riding real slow and hit a big speed bump and it will stall also. It's very emberrasing. Any ideas? I can provide more info too if any ideas are possible. Thank you!

My 99 Bandit 1200 does the same thing. It always has, to one degree or another, since I bought it new in 1999. I've messed around with the jets, and tried raising the floats in the carbs, but the problem has not completely gone away.

I'd love to hear other ideas.

Do you guys have aftermarket electrical items added on?
The reason I say that is because the Bandit 1200 was one of the very last bikes to have a true alternator on it. When loaded down that thing can stall the engine because of the torque it takes to turn it.

Other than that I'd check idle speeds, followed by making sure your choke plunger is fully in, then making sure the carbs are fully into the intake manifolds and there are no air leaks.
(According to the service manual that's a common problem)

I have zero aftermarket electrical items on my bike. However I have had the carbs off the bike probably 50 times in the past 9 years, trying to find the perfect jetting setup with various combinations of headers, mufflers, and air filters. The leaking manifold theory seems possible.

Thanks

One more thing, tho.....the bike has stalled when coming to a hard stop ever since it was new, before I did anything to it. I've been able to alter the problem, but never make it go away completely.

I would say the clutch could be out of adjustment but it's a hydraulic clutch so that seems unlikely...
I'll make a note to ask the instructors tomorrow if they have any ideas.
