I have a 1993 Ke100b kawasaki and it will start up, but after an hour or so of riding it will die all of the sudden. I know it isn't the carburator because i just put a new one in. Can anyone give me some help on how to fix this problem?

I'm pretty new to riding myself so perhaps someone has a better idea what's wrong. I would think there's a problem with air getting into the gas tank. As gas exits the tank into your carbs, air has to get in to displace the gas that just left. Make sure the air intake isn't obstructed.

How long does it have to sit before it will start again? Will it start sooner after you open the gas cap? Does it happen consistantly with a certain amount of gas in the tank?

It could be the tank vent as suggested. It could also be your coil. Some of them have a habit of quiting after they warm up. If it is the coil, it will get progressivly worse until it craps out entirly.

It could also be something else

It takes about 4-5 days to start up and it can go for an hour or so with the tank full too.

I think I'm having a similar problem with my 77 honda 360. When the tank is less than half full, the engine tends to die while at speed. Because of my clear fuel line, I know its dying because no fuel is flowing into the carbs.

The lines and petcock drain fine, but I do believe I'm having the vent issue as well. Like a straw with a finger over one end -- no flow.

Usually I pull over, switch to reserve, then back to primary, wait a minute or so, and then it starts right up.

So, Where do I find the vent?

On some bikes the vent is just a part of the gas cap, on others it's a separate line with a tube that may be crimped or clogged. To check for a vent problem, when the bike quits running, open the gas cap... did you hear a hiss? Did the problem magically disappear after opening the cap? If so... likely the vent. If not, it's likely something else.
One other likely culprit is a pinched, crimped or kinked gas line after having removed and reinstalled the tank.

4-5 days!!!!

Sounds like a seriousrestriction in gas flow. I can't think of anything else that would go away on its own. However it surprises me that with a constriction that would take 4-5 days to refill your carbs that you'd be able to run as much as an hour. So I don't know.
