    Thanks for the info. I like finding out I have good stuff already on my bike. :clap Now I just need to figure out why it gets horrible gas mileage. :cry

    The over-oiled air filter could be restricting air flow causing it to run rich.

    If it was run without the air filter that would not be good either, possibly prematurely worn rings = compression loss.

    Or too much twisting of the right wrist. :D

    Thought I'd mention it, seemed appropriate for page 500.
    Only issues so far have been dirty jets.
    Thrown it down countless times. Just pick it up and go.
    Love this thing.
    Covered in salt from riding to work after a snow this morning.
    Studding new tires on Monday. Going to ride right through winter.

    Besides the oily filter and possible worn rings, could also be jetted too rich. How much dust was in that filterless airbox? How bad is "horrible" anyway?

    Your not too far from me, and I put my KLX away for the winter a few weeks ago! I've been able to get a few more rides on the KLR in, and hope to squeeze in a few more this year. What's your winter setup, heated gloves, jacket, etc? Post some pics of your tires when you get them set up.

    I've been thinking about getting a set of these for trail riding this winter, and heading over to NH since Maine doesn't allow bikes on snowmobile trails.

    Made it, albeit slowly!
    Right now I'm running Gerbings heated insoles only. Adding a Mobile Warming battery powered base layer shirt and their gloves.
    I ordered 250 of the #1200 stud from Grip Studs in Oregon. They are going into a Dunlop D606. Can't wait, traction was sketchy at best. Was easier riding on the shoulder(and more fun)!
    Trying to save any extra wattage for more light. Been using my Cygolite Expilion on my helmet to look around corners and see the moose and deer coming out of the woods when the headlight is pointed elsewhere. It works, but is still not enough extra. I do like the function of a helmet light. Granted the last 12 miles of my commute is on a remote-ish highway that doesn't see much traffic. I either look to the right, or shut it off, if I come across oncoming traffic.

    CJ - I went to Wheaton back in the days when it first went coed.:wink: Don't remember that shop, might have to stop in and check out those tires when I go to visit some friends in Norton.
    And I did not know I could ride on snowmobile trails(really? going to double check that), going to have to go get my off-road sticker, the end of my road is a snowmobile trail in winter, as are my favorite mtn bike trails!

    From what I've read, not all snowmobile trails in NH are ok to ride on, so check first!

    There was not much dust in the air box. The used bike dealer that I got it from said the PO had traded it for a KLR so I am thinking he had an aftermarket filter that he took out right before trading it in because he wanted to put it in the KLR.

    I have only gassed it up twice when I knew it had had a full tank when the odometer was reset. The first time was before I knew the air filter was gone. I had gotten just over 42MPG on that tank. The second time all but 6 miles where with the filter and that tank got about 36MPG. Both tanks where mostly interstate riding.

    I have no idea what the jetting is right now. It has an HMF slip on and it backfires A LOT, although the backfiring has goten a little better sense putting the air filter in..

    Question for you big bore folks. Is there a market for your stock 250 cylinder? I'm about to go 300cc big bore and will be looking to sell the stock barrel.

    Yes, there is. Bill Blue, maker of the 351 and smaller other kits, may also be interested. He bores the 250 out to from 300 up to 351.

    Oh I like those!

    Watching the install video on their site they looks pretty easy to install.

    Install video can be found ----> Here

    Well, just dropped $300 on a bike I haven't even picked up yet.

    I bought the dynojet jet kit for the bike, and the FMF Q4 pipe.

    I've read enough that removing the intake restriction, jetting it fatter, and opening up the exhaust is going to transform my new, left over 2009 KLX250sf.

    I hope so anyway, I hope it is a little less terrifying to ride in traffic than the TW200. :lol3

    This thread has been full of info, and I am still not all the way through it. :D

    I'm such a bike slut.

    Just picked up a dualsported 2004 KLX 300R this afternoon. Came with a nice new skidplate (not a mark on it), FMF Powercore 4, and nearly new Trakmaster IIs. Runs like a champ and looks good as well. Needs a new headlamp and a horn. I have the horn in the barn. I'll probably change the stock gearing out to 13/42 which is a good combo for my 50/50 riding. I noticed the stock airfilter in place, so I suspect a few other cheap mods may give it a bit more pop as well.

    I love my 2006 KLX250S, but liked the idea of 28 pounds lighter and 5 more ponies even better. I don't mind kicking. It started in 3 kicks cold and about half a kick when warm. I tried riding it around but the ground's frozen and I was getting squirelly at every roll of the throttle.

    Cost me $1200 and 4 used tires. I'll get over the loss of the tires.

    BTW, the Powercore 4 is a bit louder (but it is a nice deep note) than I like. Anyone want to trade for a decent Q4 or a pumper carb and some cash?

    Sent my mistress (2011 KLX 250s) off to the local $tealership last week for a makeover. Shouted her a carbi de-restrict and rejet, a 300cc kit and a new Staintune muffler to match her Unibiker radiator guards, B & B bash plate and bark busters I put on a couple of weeks ago. Wow what a difference gone from a mild ride to a wild one, the bike now performs and sounds like how she looks. Can highly recommend these modifications to any KLX 250 owner who are bored with the other woman in our lives and wants to get more satisfaction from their ride .... cant wait till shes run in and i can really put her through her paces
    Regards

    Well after 3 weeks of waiting, I finally made the 16 hour round trip to pickup my bike, took her for a ride yesterday and absolutely love it!!

    Now to start the projects ;)

    Hoping to have lots of upgrades done before the end of January :clap

    A quick question to any KLX250 owners in Utah, AZ or southern CA:
    Would anyone let me try fitting your gas tank onto a KLX140?
    The top part of the frame seems very similar. As per Kawi lierature:
    "Ready for the off-road abuse, the highly rigid, KX™-inspired high-tensile steel perimeter frame uses the same upper tubes as the KLX250S"

    There are no aftermarket tanks for the 140. I'm hoping that the larger 250 tank may work with a minimal work to the seat/mounts/not sure.

    I'll be in those areas around Christmas & New Years.

    Thanks for any help.

    To bad your not looking around my area. I would give you my steel tank. I put on the larger acerbis and have come to realize that the steel tank sitting on the shelf probably won't ever be needed again.

    Thanks for the offer.
    I was not aware that the oem tanks were steel.
    I'm not sure if I have driving privileges in Indiana. :rofl

    Hey, I've been wondering the exact same thing - will a KLX250S/300R tank fit a KLX140?. Please post back here if you find the answer. While I don't have a KLX140, I've been thinking I may have a use for one, but more fuel would be a high priority.
