ok well tonight I heard the dreadded clacking noise on the 09 @ 5500-6000-7000 RPM**underload mostly** Sounds dead on like valvetrane noise coming from the right side topend kind of close to the little black half moons...
just wondering if any others have the noise in the 09...
trying to pinpoint the exact location
the KACR system?
Tensioners?
chain?
Piston slap, but why at that high of RPM???
Just tossing the fact out to the wolfs

2009 KLX250S stock with no smog crap..etc

 

Could just be the timing chain loosening up a bit. If so, the automatic tensioner will take it up a notch after a while and it will quiet back down again.

 

mine gets noisy up that way, but they all do. my DRZ would scream when I pushed it up there. and it's a 5-speed so it was up there a lot. like NB said, he's right but it will never be real quiet.

 

Whats goin on guys? Im a pretty new 2009 KLX 250s owner and I had a couple of questions. For one, I want more power, and heard a new exhaust was a good way. Heard about some other ways but Id like to know a way that will make the bike faster, but not overload the engine over time. Also, looking for some black plastics...or advice on rhino lining. Also, I changed the oil at 250...smart?...or did it matter? Was pretty dirty. Appreciate you taking the time to read and would love to get more advice...even the basics...never owned a bike before. K guys, thanks

 

noone makes plastics... except kawi. Exhaust, and jet it will help alot, along with the "free mods" What do u want to rhino line? Alot of people change oil sooner than 250.... but cant change that now.

Welcome aboard.

 

Hey Bryan, welcome to the forums, on the oil change, that's actually a lot of miles for the first one. Its been discussed on here at length, but generally assumed that most of the break in wear happens in the first 40 to 100 miles. I did my break in using the Mototune method, running through the gears at highway speeds using a lot of back pressure compression to seat the rings. But you have to do it on a brand new bike. Plastics probably will never be available here, although if Tremor38 would get his act together and start exporting stuff from Japan he could make bank and have a lot more friends. Hey Dean[8D] Anyway do yourself a favor and get the Muzzy, full system, and change the gears to 13-45 and jet the bike, throw the air box lid in the box with all the other stuff that will eventually come off the bike. Have fun on here and get over to the new members area and post an introduction, we don't want you to get lost in the shuffle.

 

ill post up some good reports as soon as i get mine broken in. I like the thought of the mototune break in but i dont know.

 

The 09 is Badass on the road and trails.,. , .its Fun in the mud,. . its got Awesome power., and its just dandy., bottom line,. Ive got Just under 1000 k on myne,. and No complaints,. . Cept that Whining sound in the Front Rad/Shroud area,.i need sum fix for that any One got suggest

 

Hey I have a suggestion for the noise some people are hearing. Mine has a high pitched buzz. What it turned out to be is the gas cap. Next time you are out riding and you hear it, just take your hand and push down hard on the cap and see if it goes away. I have always been meaning to see if Kawi would cover it under the warranty, I should call the bike shop and see. All they can say is no...right?

 

nah deej, it's an '09 thing. the shroud topssitagainst the tank under the seat and they vibrate against the metal/plastic meeting. a strip of that soft rubber sticker stuff would solve it. other than that, no other noises.
maybe a couple strips of electrical tape overlapping each other on each side would do the trick too.
