    Nate,

    Seat Concepts can and have made lowered seats for the KLX250S. I know because I have one.:lol3 Go to the vendors section and look at the Seat Concepts thread. They can do just about anything you want. I really like mine. I'm 5'5" and it made a huge difference. I don't need the lowering links for now.

    New seat with old foam comparison photos. The new seat is also wider in the rear and narrow in the front for standing clearance.

    I see the '09 and '12 muffler for the KLX250s have different part numbers in the parts fiche. Can someone tell me what the difference is? Wanting to get a stocker for my '09 KLX. I see a '12 that I may can buy.

    I've searched and searched but have not found any clear posting of pics of the internals of the '09 forks on the S model when disassembled. Can someone point me to this info and also to any specific shim pack/compression valve changes short of Gold Valves or Moto-Pro valves to reduce the sharp compression spike? Thanks

    I should have been more specific, I was hoping to see pics of the actual compression valve and the damper piston assembly. Thanks for your reply.

    Does anyone know if the piston in the '09 rear shock is the same diameter as the '07 back shock? I am interested in a Gold Valve for my '09 shock but RaceTech does not know what the piston diameter is on the '09 KLX250S shock. Their site shows 36mm which doesn't seem correct but when I called tech service there they did not know....

    Help! :-)

    I have an '09 KLX250S with the Kustom Kraft 330cc kit installed. Having a little trouble getting the stock 250 carb jetted. If the main jet is good it surges at cruise rpm. If lifting the DynoJet needle to stop the surging and going up a little on the main jet it is too rich at wide open throttle.

    Anyone used the KLX300 carb with the different needle jet and needle on a 330cc motor? Does it work out better?

    Thanks Rob, but I have already installed Gold Valves front and rear in the '09 KLX250S now. Pleased with the results. The rear shock is 44mm same as the earlier models. L D

    Hi there. The info in this and the other KLX250 threads is just overwhelming in bulk and diversity, wondering if somebody could give me quick answers to my questions.
    I am looking into buying a used 2009 KLX250s with 3000 kms on the clock, looks like new and the price is right. This is supposed to be a play bike to discover some local backroads and get to fishing places, no serious off-roading. I read that these bikes are finicky to start, yet have a potential to tinker with and release couple more ponies. I like the suspension specs that seem to beat the CRF250L. So my questions are:
    1) Is there some quick and inexpensive fix to this starting problem?
    2) What are some basic improvements that would give the bike a bit more oumph without spending hundreds of bucks.
    3) Do you think that this bike would fit a 67 years old guy 5'10", 190 lb in a reasonably good shape?:wink:
    4) What is the valves clearance adjustment on this bike, shim under bucket or bolt and nut?
    I am no stranger to working on bikes, I have always serviced my bikes myself and what a better past time in retirement...
    Cheers,
  14. Lutz

    1) Yes. Some drill the starting enrichment jet with a ~0.018" bit. Verify size prior to drilling. I have not drilled, and just start using a particular technique. There are other methods and workarounds too.
    2) Stock KLX300R header AND muffler (as a set) bolt on, and can be run without the "butt plug" for a pretty good increase in power. With a jet kit and the airbox snorkel removed, that's about as good as it gets with the cheap power mods.
    3) Certainly. Depending on what/how you ride, you might find the forks very, very soft. New fork springs will do a lot of good, a revalve even more.
    4) Shim under bucket.

    I need to replace the front brake hose (of a 2009 KLX250 S), as it has been chafed caused by rubbing against an aftermarket hand guard arm.

    I have an old brake hose from a 1999 KLR250, which if compatible I would like to install on the KLX. The KLR hose is a couple of millimetres larger in diameter, but its length is about the same. Both KLX and KLR hoses have 'Nichirin J1401' markings.

    My question is: is the KLR hose compatible with the KLX? Does anyone know?

    Thanks.

    I do not know for sure, but... if the fittings on the KLR hose will work with the KLX master cylinder and caliper, and the length is the same or slightly longer, then it should work fine. Pressure ratings of the hose and fittings used should be more than adequate, if not identical.
    My '09 also has a chafed outer jacket from rubbing on the hand guard mounts. The wear on mine is only cosmetic, as it has not gone through to the pressure retaining inner hose.

    Thanks for that. I've decided to give it a go, so will make the attempt tomorrow. Since posting here, I spoke with someone at Kawasaki UK who basically said the same as you, although he did stress Kawasaki could not officially approve of it.

    I've only tried once before to mess with brake fluid, and the attempt resulted in a having to ride very slowly to the local Kawasaki workshop! But that was before YouTube so I'm more confident this time.

    So I bought this KLX250S, it is 2009 model, has only 3500 kms and looks pretty much like new. However, I bought it from a second owner and who knows if/what has been done to the bike.
    Bike starts surprisingly well cold with the choke, but runs with choke about 4000 RPMs so I wonder if previous owners enriched it somehow. Without choke and warm it idles nicely at 1300 RPMs. It starts very well when warm/hot just on touch of button, no throttle needed.
    I will not be taking the carb out before the end of riding season, but I will check it out later on to see what I have in there and put in DJ stage 1 as well.
    As for the suspension, it seems to me hard even so that I am 85 kg and easily 95 kg including all the gear. I have not been off road yet, just bad tertiary and local paved roads. Maybe I am spoiled from my BMW 1200RT and have a biased judgement. Surprisingly I can almost flatfoot the bike with my 31" inseam, pretty much the same as the CRF250L that I test drove.

    ...welcome to the club.
    Your 4000rpm choke is normal, that's when it can run on it's own.
    My bike needed choke always (except on a hot day) to start, until I did my valves. Since then, it only needs choke for a few seconds before I can keep it running on a 50ºF+ day.
    As for the suspension, you'll probably need stiffer springs. Coming from the road to dirt, I couldn't deal with the brake dive...so I learned hitting the rear first, followed by some good old front, really helped tame the dive. Being able to compress the front is good when your off road, but on the road it feels not so good. It's a dirt bike first, albeit a tame one, then a road bike. Hitting the brakes really hard is like hitting a giant rock off road, at least to the suspension, ultimately it's a good thing, just different than what you are used to. The proper springs will help, a little.

    Hi 'lobolator', so how did you find your valves when you checked them out, too tight or too much clearance?
    I keep thinking about this suspension and it seems to me that I should have a softer rear spring and not harder... I rode today some hard surface fire road with lots of potholes and it felt as if I did not have any suspension at all :evil. I will try soften the preload, I am already 16 clicks out on damping, so I do not think much could be done on this adjustment... Front seems to be OK.
