    there is no doubt about that - but i was thinking vintage tech - drum brakes and air cooled..

    I've got 2. One plated with stock motor and piped, one with a big bore kit. The most common mod is RB Designs for the head and carb and repipe. Makes em tractors. I'm rebuilding the plated one now and it will be RBed! It's a bike you can put away wet and 2 kicks 6 months later it's ready to go. The swing arm bearings are the weak link. Grease em and replace every year as needed. The big bore kit is awesome but I have to run race gas in it though it is sold as a pump gas kit. Love the power but hate paying for the gas. The rear shock is talked about as being good even with weight. Respring to your weight. The big bore has a $800 shortened fancy one. I can't really tell the difference but PO spent a wad on it. The best mod I did was putting a KX500 front end on it. Bolts right up with the front wheel. The stocker is ok with 400 springs but I caught the fork underhand on a deep water rut and 4 bruised ribs and a torn up shoulder I did the deed. Everyone I ride with has orange and I have a Husky 510 but the little KDX is fun. If a ride has long sandy hills I'll grab the Husky but it feels like a pig compared. Both mine are after 96 same as yours. It didn't change. Hope you enjoy yours as much as I enjoy mine. BTW I run type F tranny fluid so every ride cost 99 cents to change the oil! The KDX is the cheapest lil woods bike out there.

    My KDX220 is about as fun and reliable as they come. I did quite a bit like KX front end and a Rev-Loc and some other mods.

    I have a 250 KTM XCF-W also and it is hard to decide which one to ride. The KTM will be the better choice at faster speeds and rougher terrain. The KDX is just plain fun in the woods.

    I stuck mine for sale in the flea market and put a "I don't want to sell it" price on it. Most likely take the listing down :)

    Good choice!!

    I haven't picked it up yet (it's in safe hands, and the garage needs a little re-shuffle.) I'm becoming pretty excited. Couple of questions.

    1: What can I reasonably expect for range? It has the stock tank. The rear fender/light sub frame looks like it will accept a Rotopax mount, so I will probably stick an extra gallon on it. It doesn't look like the available replacement tanks are much of an advantage.

    2. It's plated, but not strictly legal. I've been looking at the same Tusk kit that made my DRZ400E compliant. What's there for stator capacity? Vermont really likes a high and low beam on plated bikes, so I'll likely replace the headlight. It's my only concern. Horn, LED signals and the lot can be run off of a total loss aux battery. It's not a bike that's going to go cross-country.

    3. I really want to set this bike up for low-end grunt. I have two dual-sports of varying intensity. The KLR is frankly a bitch when the going gets technical because of the weight. In sand, it's a nightmare. I'd take it cross-country in a heartbeat, however. It's my do-everything to some degree bike. The DRZ is much more worthy on the hairy stuff, but wearing for a long day which includes pavement. That being said, it'll do 300 mile days without complaint, in reasonable comfort, and will hold camping gear. I see the purpose of the KDX as giving me a big grin within 150 miles of home. I'd still like to be able to pack the necessaries on it -- warm stuff, rain gear, a little extra fuel. Any set-up advice would be greatly appreciated.

    Is that a trials rear on yours? I've been considering one. Local terrain is rocks/roots/loose mud. There's little sand and very little sticky mud. VT doesn't bust you for non-DOT tires. I was thinking that a trials rear might be the ticket.

    Checkout the pirelli MT 43 thread or trials rear on a dirt bike thread. Sorry, can't search for some reason. I;m thinking of putting one on my DT 230 next. With a decent mountain bike pump I can ride to the woods, drop the pressure to marshmallow, bless my rim locks & pump it up for the ride home. A number of extreme enduro bikes (erzberg etc) run them on the rear.

    Best thing I have ever stuck on the back of a woods bike. It goes through everything. I run about 7psi with dual Motion Pro rim locks and an ultra heavy duty tube. I leave guys with knobbies spinning on the rocks and roots. It is almost unfair.:lol3

    Only times I noticed them not being as good as a full knob was in pine needles and when you really need power in sand whoops to stay on the tops of the whoops. Mud was not an issue. You just need to ride smoothly.
    They give up some on steep downhill braking if you lock the back brake.

    Run the same deal on my KTM.

    and..yes they get very muddy. Just happen to be clean here.

    Just scored the appropriate Race Tech rear spring for my weight/riding style. I used Race Tech's online spring calculator, and then found the correct spring on Ebay for $60 shipped.

    There is someone parting out a KDX 220 in the flea market that has a Baja designs kit with a tight looking rear fender and led tail that cleans everything up. It's been on there for awhile so just dig down. I have both types of aftermarket tanks but don't know the range. Does help but not mind blowing. Would still recommend getting one if you ride with 4 strokes. I carry a little bit of oil just in case but you can run them with straight gas in a pinch and not kill them. Just for emergency. There is a method to riding on the street with these that I heard but again forgot. I think you roll of the throttle periodically to get some oil to the rings. For tight woods check the RB mods. Makes them feels like a 4 stroke, meaning getting torque down in the low rpms and staying off the pipe. I stay in 2nd on tech stuff with no bogging. There is lots of info on kdxrider.net as well. It is the other site for kdx heads. Good luck!

    I'll check that out on the Flea Market, thanks! Def gotta keep up with the 4 strokes. So far as I'm aware, none of the riders I'm likely to be with locally have a two-stroke or less than about 100 mile range. The PO said he was having good results just bringing a quart of two-stroke oil and letting it mix in the tank when racing hare scrambles.

    Enjoy the Kool-Aid

    You will not regret the acquisition, I owned one for 15 years
    and loved the bike dearly. If you are buying it from who I think you are ive seen that bike personally and its in great shape!

    Its a tame yet snappy and fun engine.
    The woods pipe will really help the low end.
    its 220lbs dry, it will feel like a mountain bike compared to your KLR.

    Check Fredette Racing for setup guides.

    I use to mix in the tank on long rides, I remember riding about 50miles on a tank and never ran empty. I was just too exhaust to ride further.
    I think 100 miles might be pusing it however that all depends on how much go juice you apply and what type of riding you are doing.

    Upgrade the suspension and ride the bajesus out of it!
    and then someday they will write a book about how good you can ride! :lol3

    I stopped over at Jackpiner57's place yesterday, and loaded up my DRZ400 "E" with some sweet rack mods, and then slapped Tom's KDX on the trailer. First, we mixed up some fresh pre-mix. The KDX sat for over two years in Tom's shop. With a fresh charge of gas, it all of three kicks to bring it back to life.

    There can be no more mosquitoes within a five-mile radius of Tom's shop. The KDX smoked a bit until warmed up, then settled into a nice "Maytag full of Crescent Wrenches" idle.

    Tom was obviously hurting letting this trail monster go. He took it for a few spins up and down his road, spraying gravel and grinning like hell.

    I forgot to throw a helmet in the van, and I sure as hell wasn't going to ride that beast without one.

    However, I got it off the trailer, and today thought I'd take it out for a pop. Haven't ridden a two-stroke in about fifteen years. The KDX is supposed to be pretty mellow. Got it out on the gravel drive, all nicely warmed up. First, no problem. Front is light, but planted. I'm being conservative. Second, same. In third, I threw on the slightest bit of stick, and the front just rose and kept coming up until I chopped. I'm not a wheelie guy. As a matter of fact, I've never wheelied intentionally, unless I needed to hop over a log or something.

    Seems I've entered into a whole different ball game.

    I kinda like it.

    37 HP is about 12 high for a really good running KDX,even with a pipe/porting/head mods 25hp would be pushing it.
    Im pretty sure 18/20 hp is what they have stock. They arent fast but make great little woods bikes,just gotta buzz em and row the gears to make em move well.
    A KTM200 might approach 35 hp at max buzz and weighs less and less the newer it is.

    Google KDX info and some kind of power output will pop up somewhere.

    I have no idea how much power this little pig will produce. It's got all the good stuff, and is light and kind of high strung. All I know is that I twisted it the smallest bit on in third. and up she came. That's plenty good for me. I don't need no dyno.

    37 is claimed here:http://www.motorcyclespecs.co.za/model/kawasaki/kawasaki_kdx200%2005.htm

    I measured my mileage on a correctly jetted 200 trail ride, 3-4th gear average, on/off throttle, and get 35 MPG. For the stock 3.2 gallon tank that gives you 100 +/- to empty. 2S do not get as good gas mileage as 4S.

    Here's my modded (RB designs - carb and head, and with KX forks) KDX220. Also with Gnarly woods expansion chamber and stock silencer. I get 95 miles before switching to reserve on stock tank. My thinking is that it'll get about 115 miles to empty.

    Here are some old dyno (2000 vintage) curves comparing the two; but probably no longer true today with the newer KTM engines. Both show HP in the 35 range.

    There is no reason to carry a quart bottle of oil with you for gas refills. You only need about 2.5 to 3ozs of oil per gallon of gas. MSR makes a nice little bottle and container that fits on a belt or pack that would take you out to 200 miles range pretty easily. The carrier is made to hold like a 12 oz bottle of pre-mix oil (concentrate). Several companies also make these.

    I'm seriously thinking of taking it to finish off the bottom half of the UPAT next summer. I'd need to pack at least a quart of oil for that.

    Jackpiner57 has built a one-off rack for another inmate's KDX that worked pretty well. He's going to borrow the bike so he can build jigs in case any other KDX owners want one. A decent top rack and/or a Giant Loop bag would make it overnight capable.

    I got my 2001 KDX 200 a year ago. I put a Tubliss rear with Pirelli trials tire on the back, woods pipe, and race tech fork springs.

    I absolutely love the bike and don't see me ever getting rid of it. It's competitive in harescrambles but just as happy to plod along behind the kids on a trail. And it's very cheap to operate and maintain.
