I bought a brand new 2009 klx 250s. BRAND New. 4500 bucks OTD. Ya I got raped I know. The day I brought it home it wouldn't start. Ended up getting it fired with some starting fluid. Everytime I try to start it I run the battery down to nothing with not even a sign of life in the pos. It'll start with starting fluid tho if the battery lasts. So far i've only done a few laps around the back yard. Brand new bike. I was just outside trying to adjust the shift lever, ya that ended up in a rounded bolt. FML on that one. So I decided to maybe start it. I've done all the starting dance moves to no success. It just bugs me to the point I'm thinking "I shoulda bought a HONDA". So, with 4500 invested and no hope of ever getting that money back I need step by step instructions on how to adjust the carb to get this bike to fire. I went and bought the #77 drill bit, i'll probably break that off in the carb....... I hate throwing money into a brand new bike just to get it to run. It's rediculous. I'm debating about calling Kawasaki and giving them a piece of my mind on there product. I have a polaris quad, now that's one lean running machine. It'll start, but you gotta play with the choke to keep it running till it warms up. Atleast it runs. So that's my rant to go with the starting dance.

So the question is, what do I need to get this bike to fire. I have the drill bit. I'm going to charge the battery tmrw and pull the carb. It's getting brand new gas and a spark plug for ****s and grins. I'm not looking to make the bike more powerful, just want it to start and run good. Do I need the dyno jet kit.... Looking for step by step instructions of things to watch for and avoid when playing with the carb. I will admit, it's 30 degrees outside, but the bike was run yesterday. I want a bike that will fire. I live in Northern Michigan, temps swing all the time. I don't want a bike that I question if it's goin to start.

 

for grins, your fuel tap is on and choke pulled out ??

 

yup, everything I can see. Choke and gas is on. Ran great yesterday once it fired. I called the dealership I bought it from and I got the it ran good here. Bring it in, we charge 70 an hr. Well, i'm goin to save 400 miles on my truck and gas money and take it to a mechanic up here before they ever see this bike again.

 

Mine wouldn't start when I got it home from the dealer. And they had a really hard time starting it at the shop for its check before I bought it. Was thinking of not getting it when I seen the trouble they were having. But other than drilling the starter jet(wich I have yet to do) It does get easier. You just learn how it likes to start after doing it a bunch of times. I know I was ready to burn mine a few times...and I have killed the battery more than once, but I can get it running pretty quick now with playing with the choke

 

treerat, I'll say it again...and not being a "search ****"...have you read some of the recent posts here in recent history that show pics and give descriptions on drilling the starter jet and jetting the bike? It's not that I or others don't want to share basic info, but most of this basic info has been shared...and shared...and shared. Now, after reading many of the posts about these procedures, you may indeed have a specific question about this or that, but all of what you're asking has been covered even in recent time.

One thing I detect in your post that you probably need to consider...frustration. Don't go into a job or project with a serious buildup of frustration. You really need a level head and hopefully a somewhat enthusiastic attitude...or you will break stuff, do it wrong, or give up. What's wrong with your bike is relatively small in the realm of motorcycling. You'll have a waaaay better machine by rejetting and just drilling the starter jet.

 

mine wouldnt start for two days.. I had just touched the kill switch.. not enough to flip it to off.. just a micrometer enough to not contact.. I went nuts.. finally flipped kill switch off then on again... fired right up..

 

"So the question is, what do I need to get this bike to fire."

I think that this is your only question. If everything is working as KAWI intended AND temps are cold then your choke is not choking enough and you need to drill the jet and adjust the fuel mix screw. Only a few oddball bikes start reliably without this fix in cold weather. You will be so far into the bike that you may as well install the DJ kit while you're in there and the DJ kit comes with the screw and bit to remove the EPA plug that is now preventing you from adjusting the fuel mix screw.

I ordered the DJ kit through amazon and it was 55$ to my door. Starting on my bike is night and day better in the cold weather. Hot restarts are also much better. I have factory air filter, intake, and exhaust.

Be ready to remove the seat, rad shrouds, and fuel tank. Then the carb lifts right out.

I recommend getting the DJ kit now and installing it per the directions PLUS drilling the choke jet.

 

I think before you starting with jetting, you may want to consider just replacing the battery. Yes, charging it might help but it sounds like the battery. When you turn it on, does the dash light up?

And as Tiger said, it could also be the kill switch.

BTW, did the dealership start the bike when you where there?

Sorry to read about the problems. I know it must be frustrating, it would be for me.

Either way, good luck.

Good point on the battery. The '09s starting coming out in summer '08 so if this happens to be one of those and the battery wasn't properly maintained it could be incapable of holding a good charge.
If it's cold and the bike doesn't want to go right away a Kawasaki machanic told me to hold the front brake and pump the bars up and down while cranking with the choke on. Splashes a bit more fuel into the throat. Worked for me. YMMV however.

 

Thanks for the advise, now that i've calmed down and can see straight I guess i should just order a dyno jet kit and when putting that on I can drill out the choke. I'm just afraid of messing up this carb cause i've never worked on a CVK. Sounds like it will run all around better after I do the dyno Jet kit and choke, so that's what I'll do.
