help! bike stalls out after a few minutes of running!

hey everyone, im glad i finally joined a KLR forum! but anyways. i have a 2000 klr and it ran great last summer. i put it away for the winter and now the other day i finally get it out and im driving down the road and it just stalls out. to get it re started i had to open the throttle all the way up and start it?! i havent touched it since winter so i know i didnt adjust something wrong or anything. it fires right up after its cold, but after a few minutes it'll just putter off and stall. i also noticed the rpm's higher than usual when its just idoling. i tried letting it run with the gas cap off and it still does the same thing, the air cleaner is fine. im guessing its a fuel problem. could the float be sticking in the carb?? or a fuel filter? i need to get it runnin asap since i have to take my driving test soon. any advice will be appriciated. thanks--snuffy

Did you use Stabil in the fuel last fall? Did you drain the carb? Is there fresh fuel in the tank?

What I would do is fill the tank with fresh fuel if you haven't. Add either Sea Foam or a bottle of Chevron Techron additive. Then drive it till that tank of fuel is gone. Should be good after that.

I'm with you on this one. I keep minimal fuel left in my tank, add a stabilizer, ride around a little to get thorough everything, then add a fresh tank of fuel when I'm ready to ride in the spring. Bikes usually not started from Nov-March. Seems to work.

Also I learned not to start it during the winter. Seems to just kill the battery and foul the plugs.

Do what I recommended before you go yanking the carb. Why do something difficult when for $10 you can try fix it on the bike??!!

Fresh gas is one thing but leaving unstabilized fuel sitting in a carb over the winter can gum up a carb.

I used to have a couple of Honda CBX's, 6 carbs and never had an issue. Full tank of gas with Stabil, run it through the carbs, and let it sit for the winter. In the spring syphon out the old fuel, put it in the wife's car, fresh fuel in the bike and fire it up no problem. When I sold the bike the new owner called in the spring with carb problems. Put in a bottle of Techron, road it off and all was good.

Rusts out your exhaust system too.

I'm with KLR4evr. Seafoam. Then let it get complicated. It might not have too. Seafoam is cheap and easy.

Sea-Foam is easy to find and does the job. It might take 2-3 tanks to be 100% but it will get it done.

AND NEXT FALL don't forget to put the bike away properly.. It'll save you time and hassle in the spring..

I tossed in 3 oz. of Stabil and filled all the bikes, rode them 10 miles to get it throughout the system when I put them away last fall.. All of them started instantly this spring, even my grumpy BMW Airhead which can be grumpy in 90 degree weather when everything's perfect..

And just do the simple things first.. If Seafoam doesn't work, then be concerned about tearing the carb off..

One other item.. If your gas tank pressure release button isn't working, you might be getting a vacuum in the tank and not getting fuel to the carb..

This is in your gas cap, and is the thing that whines when the tank's hot in the summer.. WEeeeeeee.. One way to test for this is to leave your cap loose and see if it's doing the same thing that it's been doing, in the same amount of time.

If it dies with the cap open, you've eliminated that possibility.
