    Cheers. I bought the bike used with 3,000k/m on the clock. I can't believe it is still going strong,I don't exactly mother it.

    It was my main ride for many years: commuting, freeway work down to the coast in the summer, transporting a chick home the night after when I was lucky enough, etc, etc

    All the bottom end is original. Threw an KiP into the barrel when I first got it and had to replace the top end. That was when it was jetted from the factory and way too rich for its own good.

    Having a big 60,000th birthday celebration this weekend, and then it's more clouds of the old blue smoke heading towards 100,000!

    Whoa. You're saying you put ~55,000 on a single top end? Wow. Nice work.

    My bad. I pulled the top end again at around 30,000, cleaned the exhaust valves, and put a new piston, rings, and small end bearing in place.
    There's 30,000 on the current engine. As, you can see on the video, it's pulling fine and there's no excessive smoke, so I will leave it be for the time being even though I was planning a complete strip down at 60k.

    The carbureter manifolds are prone to crack and leak, so I have been changing them quite often.

    Still, that's pretty impressive for a two stroke dirt bike. :clap

    Totally agree Airhead. I just hope I haven't jinxed the bike now!

    In my opinion the 90's were a golden era for Japanese motorcycles. The Japanese economy was kicking all manner of ass during this period. (Bubble Era)
    The bikes produced just for the domestic market, or limited export destinations were awesome; components straight off race bikes, best materials, top-notch build quality, especially when you think about what else were in the shops at that time.

    The KDX250SR engine for example is basically the 1989 KX race bike with mods for street use: heavier fly wheel, wide ratio tranny with lower first and second, but tall fifth gear.

    Not sure about the U.S and Australian markets, but a whole 'grey-import' business sprang up in the U.K. Bikes only made for the Japanese domestic markets being privately imported to the U.K: CRM250's mk1, mk2, mk3, AR. NSR250Rs, TZR250s, SDR250s, R1-Zs...

    Then they went and stopped production of two-strokes...:hmmmmm

    Got an original seat from evil-bay for 10 bucks. Makes the bike look more like the '89 KX that it was based on.

    Great weather here in October: One nice blue sky, two strokes, and a couple of three pointers.

    Nice work, I had the 89 DT200R from brand new here in Aus, great bike. My mates were laughing at me when I traded my TT600 on it, until we went riding and I kept up with them on the Forrest roads and left them in my dust when it turned single track

    The DT200R is a great bike. My mate had one in that lovely Yamaha IT blue.

    The later 1990's DT200WR was a whole lot of fun as well.

    Yamaha exported a load of DT230 Lanzas with the TCS (Traction Control System) Down Under. Did you ever ride one? Perfect farm bike.

    I tried to buy a 230 recently, he wanted too much for it so I was holding out on it when a nice older WR450F came along so I bought it instead

    A WR450 instead of the 230 isn't a bad compromise! :lol3

    Have a great weekend down there in Brissie BygDaddee.

    I have seen a couple of these come up for sale around here recently.

    I have been keeping my eye out for a KDX200 and noticing a few 250s.

    I was staying away from them because I really wanted another 200, but I might give them a look after seeing this thread.

    I don't know much about the 200s.

    I am by far no expert, and there is a ton of info on the web, the general consensus being that the 220 is the best of bunch in dirt. The 250's suspension being considered too soft and the bike too heavy.

    That being said, the 250 was my main commuter-in-heavy-traffic-for -years bike and it never let me down.
    The lack of a battery means it can sit outside under a cover for months unused and just fires up first or second kick.

    If you decide to get a 250 and it has been run for any time in stock condition, pull the top end and clean the KiPS valves. Toss the stock pipe and muffler as far away as possible, air filter, reeds upgrades, and DEFINITELY get the slide and needle sorted out. It will never run right without doing this.

    Jetting: 38/158 , R1367H needle 3rd clip from top, #6 slide would be a good starting point.

    I machined 1mm off the stock slide because I couldn't find a #6 slide.

    Coming home from the park yesterday I had some fun off the lights with a kid on a distant cousin of the KDX, a Kawasaki D-Tracker with a hopped up 300cc motor.
    Just good old clean fun. Well, good old two-smokey fun in my case!:wink:

    I bought my 09 husky 300 brand new. At 4000 mile mark it still runs awesome and has perfect compression. Yet people give me crap about not replacing the piston by now. My attitude is why? Thing runs awesome. Never understand fixing things that are not broke.

    Thanks for posting this. I want to see you get to 100k

    Totally agree Firecrotch re: fixing things that are not broke.
    Thanks for the encouragement to reach the 100k mark. A ways off yet. But as John Lennon said, 'tomorrow never knows'..... and 'I am the walrus'

    A rare black KDX250. I have been passing this sad bike on my way to the gym for the last 7 years. I do so hate to see a bike rot away slowly like this.

    I wish I had a garage.

    As you can see it was ran in stock trim and paid the price for it.

    I would wager my bottom dollar the bike ate its own top end with a KIPS melt down from being ran in stock form.

    Only 11,000k on the clock.

    :waysadHeart breaking, but I do not have the space to store the bike. I have used up my allotted 2 bike parking spaces in my apartment.
