    I bought a KLX300r a month ago and the poor little beast doesn't have a thread of its own so I figured I'ld start one.

    Here is mine:[​IMG]

    This is its big brother in my garage:

    When I got mine it had about 500 miles on it and was completely stock. I have started moding it.

    Bash plate
    lever guards
    Crankcase breather
    Dynojet stage 2 kit
    ACR mod
    Renthal bars
    took top off airbox
    Exhaust tip removed
    Tail bag
    fender bag
    T-mod for carb vents
    Acerbis headlight


    In the future I'ld like to add

    Bigger stator
    Heated grips
    Acerbis tank
    Fourstroke works header

    I know there has to be other KLX300 riders on the board.

    Happy Riding:ricky

    Funny you should start this thread today.

    I just got back from the first shake down run on mine.

    Although mines not a true 300, it's an 04 250 with a 97 300 motor in it...

    But here is a pic of the donor bike...

    And in action.

    (Before anyone asks I put the 300 in because I blew the 250 up, and yes I had a 300 kit in it anyway...)

    I have a KLX300 with the 331 BBK (compliments of PO) from Jerry at FSW. Came with Renthal bars. I've added '95 KX250 forks and raising links for the rear to maintain geometry. I also procured an FCR35 - ebay seller didn't know what he was selling (thought it was a 39) which I'm presently tidying up. I need to freshen it up with rings and valve guide seals cause it smokes for about a minute after startup. Also added aftermarket footpegs, fender bag, and a new cap for the stock exhaust. Getting ready to add a dualsport kit and change the granny gear 13T IIRC front sprocket for something more roadable. Starts 1st or second kick and easy-peezy to ride anywhere. I'm paring down the stable but the KLX stays. That's right - my LC4e goes before the KLX. Gotta love the simplicity.

    What other mods did you have to do to add the 95 kx forks? Did the stock triples and wheel work??

    Ironbrewer - If you use 94 or 95 KX125/250 forks you can use the stock KLX triples, wheel, calipers, rotor, etc but need a spacer to line it all up. A gentleman on thumpertalk used to make the spacers. I had to change the front brakeline cause the KLX has a lug built into the fork lower end for the brakeline. Used a piece of hardware to attach it to the upper end of the KX fork guard like most modern dirtbikes. The KX forks are completely adjustable (compression and rebound) with a longer travel. They are about 1.5 inches longer though - so I raised them up in the triple - 3/4" - and used the raising links to raise the rear. It's a taller bike now but has a leaner, rangy look to it. Much safer on the side-stand as well. No longer wants to dig in and fall over since it's more upright.

    rwamf,

    Why do you like the clarke tank over the Acerbis. I would think the radiator protection afforded by the Acerbis would make it the choice tank.

    My 300 gets 50 mpg and the stock 300 tank was 2.6 and that was good for 125 miles, and thats riding hard, But the new 250 has a cooling fan and the 300 tank won't work, the Clark is 2.7 so I will be at where I was, the Acerbis is 3.7? this is not an adventure bike, it is a fun dualsport, and 100 miles between gas has been fine so far, I thought about the 3.7 but I have other bikes for the longer rides.
    I want to keep this a small bike for gnarley single track, that is where I will ride it so I don't need the extra bulk.

    rwamf - you're the guy to answer this for me. I'd love to add a light rack on the back of my KLX300. I'm wondering if the frames are the same between the 330 and 250s - the rear half that is. Would the KLX250 rack work for me?

    Thanks

    I'm running 15/48. Seems to do well if you keep the freeway stints short...Top speed is around 82-85 so cruising at 65 seems to be fine.It does like to vibrate with the Kendas on it.

    Sorry to say "Simple answer NO", the 250 frame has special brackets welded to the frame, yes it could be done but it would not be cheap.,

    That's Great, but it is "Not an Adventure bike" for me, that is why I have a GS ADV, I am keeping my 300 for the tight, tuff , nasty single track. so keeping the mass down is important.
    The bike is the most reliable bike I have ever owned and it is more than capable of going or doing what ever you want, but when it comes to long trips I like 85hp and 80mph on the dirt.

    But you don't have to fill up the gas tank, and the wings on the Acerbis tank are light protection for the radiators.

    If your not going to use the extra fuel the Acerbis has to offer can I have it?... I mean I woulden't bother.

    It does make it noticeably wider between your legs.

    I only have one because I need all the fuel I can get with the places I ride.
