99 klr 650 turns over and dies after a few sec

Any veteran pointers on what to check first? it was running great until it just randomly started doing this, this morning. first thing that comes up that the manual says to check, is choke plunger system... but then the manual doesnt follow up with how to actually check it!

Do you leave the "choke" (starting enricher) "ON" after starting, giving the engine some time to warm up?

At what temperature do you experience this phenomenon, and . . . does it happen when the bike engine is warm, or cold only?

Total speculation: You may not be running with choke in mixture-richening mode long enough. Otherwise, with an idling warm engine, just barely nudging the "choke" will kill the engine.

On "checking" the "choke." The mechanism is pretty simple; cable withdraws a plunger from the carb when ON. Definitively checking somewhat difficult; a nut secures the cable to the carb body; you can loosen the nut and observe the action, but . . . awfully hard to re-thread the nut into the carb . . . if you try it, you'll see!

its been operating perfect, unitl now, i dont touch the choke, i know that will kill it, it cant warm up now, because its shutting down after a few sec. its cold, because it doesnt stay on, this isnt intermittent. it has happened and now the bike will not start

Have compression, spark, combustible mixture?

Internet's an imperfect communication medium; don't know whether you put the "choke" ON or not when starting; KLR650 engine's somewhat cold-natured, might need the choke on for awhile to sustain operation.

dopfreerain,
How long have you owned the bike? How many miles have you put on it?

How full is the fuel tank? Maybe need to turn to reserve? Maybe the vacuum hose from top front of carb to fuel tap diaphragm is loose fitting or cracked and leaking off vacuum and can't fully open the fuel valve.

What temp is your location in the mornings?

We really need more info from you.
