Are you pulling the choke? I heard Starting fluid can be like drugs. Once your bike uses it it gets addicted. Maybe the choke circuit in the carb is gummed up. Go Green

Adjust the valves mine did the exact same thing. Starts first kick now

Drain the carb bowl, and try it again and report back.

Starting (choke) jet in the carb drilled to .018"? That's what did the trick for me...

This bike needs a re-jet and it should fix the problem. Another issue is when the bike sits for a weeks or so will not start. Tilt the bike to the right for about 5 seconds and it will start right up. Or drill out your choke as stated above.

Bump for an update: ???
Anyone having trouble starting the KLX after its been sitting for a week or longer, the drilling of the jet sounds like it fixes it, but if you dont want to do that then just give this a try till you do.
I've probably posted this here a dozen times, and if you have read this before I apologize in advance. But when something works every time, not just most of the time, you want to share it with as many people as possible. I own the 2006 KLX 250S Dual Sport, and the 2006 XT 225 (Wife's bike) and on both bikes, if I don't follow my own advice and procedure when leaving the bikes sitting for more than a few days, they will not start period! But if I follow it to the letter, I can guarantee the bikes to start even if its been a few weeks or months or even if the temps are in the low 20's. So without further adieu, here it is.
Shut down procedure.
1. After riding as you are pulling into your driveway, or to speed things up you can do this a block from your house, turn off the gas.
2. Let the bike run until it actually dies from gas starvation, (this may take 2-5 minutes) But that's ok it will give you time to put away your gear.
3. Park it and now you're ready for the next time you ride whether that be in a day, or a month.
Start up procedure.
1. Turn on the gas
2. Wait for 10 seconds
3. Start the bike as you always do
I guarantee this will get the bike started every time.

I am lazy or don't own a drill but tipping the bike works every time!
Yes tipping the bike causes the fuel to dump out through the overflow tube, which accomplishes getting fresh gas in, but then you got gas all over the ground, come on man I'm lazy but not THAT lazy LOL

Tablespoon drop is still ok by EPA and Serria Club. Actually they encourage us as it helps reduce the mosquito population.
