    you klx250 folk shouild try to talk Clarke into making a larger tank, group buy , that seems to be the biggest problem with the bike,

    if kawasaki had a brain they would do it, then offer it as a option, it just shows how bike mfr ( most all others are guilty too) really have no idea how there products are used. amazing they can stay in business at all.

    looks like a great bike.

    I'm getting about 90 miles before reserve on mine.

    I'm going to go ahead and order either the Acerbis or Clarke tank for the KLX300 and see if I can make it fit. Another gallon of gas is all this bike needs right now. A Staintune and some carb work are coming in the Spring.

    Hey all, just thought I'd chime in here. We bought a KLX 250 also, for my wife to ride. I ride a KTM LC4 and she wanted to be able to go along too. I am having to set it up for her height (5' 2") by using Kouba links and running the forks up into the trees about .6" and that gets her pretty close. Today I will be pulling the cover off of the seat in order to remove about an inch from the foam before re-applying the cover, which should be the final step in the quest for proper seat height for her. We only have about 200 miles on it so far, but it seems perfect for her power wise. I personally dont see how anyone with any experience on a motorcycle could be satisfied with the power output of this bike, its pretty anemic. But I'm not riding it, and she loves it so I guess thats definately what matters the most. We'll be glad when FMF builds a pipe for it so we can uncork this terribly restricted little bike. I think it has alot of potential for increased power gains. Until then, we will just ride the heck out of it.

    Randy.

    I could never figure out why Kawasaki didn't offer a bigger tank either, it's a nice bike otherwise. When these 250 DPs were popular in the '90s here in Japan, Yamaha had the 4.2 gallon TTR250 Raid, Suzuki still has the 4.5 gallon Djebel, and Honda had the 3.7 gallon XR250 Baja. A couple months back I bought the Honda :D

    There is supposed to be an FMF already that fits -- also, a full system Big Gun EVO X with spark arrestor, and quiet (92-94 db) insert with it.
    Four Stroke Works has a larger header pipe, that users say gives them power gains even with the stock muffler.

    Post here just how far up you were actually able to get those forks -- 6" is maybe not do-able. Mine are up 1-3/4 inches, along with the Kouba "X1" lowering links, giving a seat lowering of a little over 2 inches. I might cut my seat down, too, for more lowering.
    Those forks will probably need shimming (like my bike did), since there is a full 2mm difference in diameter, of the top (where the clamps are now) and the fork tube down where you want to put the top clamps -- I was thinking the clamps look like cast aluminum, and with that much bending, might crack in half when tightened up enough to cinch down 2mm more.

    Yeah - I just gotta see the bike that had the forks run up the clamps six inches.

    A lot of today's factory dirt & dualsport bikes are lean & restricted on the intake end. Like I ran my DRZ with the 3x3 airbox mod, jet kit, but stock pipes. If the intake is restricted and the carb is lean to begin with, that limits what can be accomplished with the exhaust.

    What do 250S riders do with the intake end of things?

    I agree that the bike could stand to be uncorked. Muzzy and Big Gun make full systems that will fit as does Staintune. I'll be fitting one of these as soon as I solve the fuel tank challenge. I don't want to do anything to take away from the MPG until then.

    Don't judge it too harshly until you've had a chance to really ring it out. It makes good power above 6K RPM even in stock trim. Also remember this bike is geared for the street. Drop a tooth up front and things get a lot nicer offroad.

    Before you guys start spending hundreds of $ on pipes and performance parts, have you done, or confirmed that the same free hopups can be done as the KLX300 ? Has anyone taken off their 1" crankcase vent and found a plug with a 1/8" hole in it ? These are where you will get the biggest gains and they are free ! After that you can spend another $800-1000 on a pumper carb & head pipe if you have more money than you know what to do with.

    The KLX250S has a different crank vent setup than the KLX300R. The 250 already has in effect what results from doing the mod on the 300. In fact, the entire airbox setup is very different between the two bikes due to the fact that the street legal 250 has to have an air injection system grafted on to it for the EPA.

    Can you explain what you are saying? re: 'The 250 already has in effect what results from doing the mod on the 300.'

    I'm saying the 1" crank vent hose to the airbox is restricted internally by a plug which only has a 1/8" hole in it. This in effect causes a crankcase pressure & vacumm because it can't breath fast enough at higher rpm. Remove the plug and voila... it revs freer.

    The plug's not there on the 250 and the hose is already routed the way it's suggested to do it in the mod documentation for the 300.

    Is there any thing else that is considered a quick fix such as the item(s) above folks? These are the kinds of things that usually make as big of a difference as anything, as was so well put already by Gybeman.

    I'm all ears:ear

    Well I got the seat cover back on tonite, first seat re-do for me. Hopefully my last, that seat cover re-install is a bitch. It was worth it though. I have now taken a full 2" out of the seat height for the little woman. Factory specs say it has a 34.8 seat height, I'm now measuring 32.7 on ours.

    I checked on the exhaust's mentioned above and the only one that gave a price was Big Gun, was'nt too bad either at $474.00 for a full exhaust system. I would prefer an FMF Powerbomb system so we will probably wait around to see if they come up with one for the little 250.

    After I got the seat re-installed, I decided to take it out to the track behind the house for a spin. We've got almost 200 miles on it now so I thought I would see what it was made of. Now I am 6'2" and weigh 220 lbs so I was'nt very convinced that this sucker would pull me around very well. It took me a lap and a half to get used to the non-exsistant bottom end, but after I started really pushing the rpm's, I could feel the front end starting to get a little light coming out of the corners! After 4-5 laps, I got more than a few wheelie's, Ya just have to abuse the hell out of the clutch and the rpm's. After that, I figured I'd better chill since we really bought this for her and I was being pretty hard on it, so I cruised back to the house with a smile on my face and had some new respect for the KLX Two-Five-Zero.

    Catch ya later, Randy.
