I have been helping a friend find a bike so I have someone to ride with. We test rode a 1994 CR250 a few weeks ago and it was an absolute bucket. I gave it a thrashing because the goose told us it was great condition, HA the back brakes and kick starter were fugged for starters LIAR. Almost everything on it needed attention. He wanted $2650 I offered him $1200 and left my number. Needless to say its back in the paper for $2200 this week. Today we drove 2 hours away to check out a 1994 KX250, it was very well looked after but very pricey also, $2750. The good news is (if you can't tell by the topics name) we pick up his 2000 KX250 at 8.30am. I talked him down from $3750 to $3000 before we even looked at it.
Has anyone got any info they can offer on this model ??
Any suspension pros / cons Jason ??
I appreciate your help on this guys as it will be stored at my place and maintained by myself. At least I get some practice on this beast before mounting your beast Jerry.

That year was a favorite among off-roaders, but not as much in the MX dept(stock). Smooth motor and soft susp are the reasons for above. Here's a review I dug up:
2000 KAWASAKI KX250
Long a favorite in the engine department, the 2000 KX250 is a gentle powerhouse. Kawasaki is guilty of letting down its guard and letting the rest of the bike become dated. The suspension is ridiculously soft at both ends. It finished fourth in the 2000 250 shootout.
TEST BIKE WEIGHT, NO FUEL: 230 lb.
PEAK HORSEPOWER: 45.5 @ 7500 rpm
Here's what I am currently doing to my 2002 KX250.
First, it's the same bike as your friend's. 1999 to 2002 were the L series. All parts are all the same.
I have the clutch apart to send into Garry at EFM for the autoclutch treatment. The clutch is simple to work on and an air impact wrench will spin the nut off, no problem. If you are going to get your KDX clutch modded up this way, send in both and recieve a $50 off each clutch for the order. (Don't tell your friend and apply the whole $100 to your order.)
My next mod is to send the barrel and head into Eric Gorr and get the 310cc big bore kit. I've read up on it on the other site and the guys who did it rave about it. Here's why:
The bore job lower's the porting by the nature of the port routes. As the barrel widens the port route is coming up from below so that lowers the ports. Shaving the base does the same thing without the bore. The report is that the KX turns into a low to mid rpm tractor with tons of horsepower without loosing any topend and overrev. The KIPS is also shaved to match the bored barrel so it won't interfere with the piston and rings. The piston is a standard overbore from wiseco, so that's an off-the-shelf item. The head is reshaped to compensate for the larger bore cylinder and the squishband is reshaped as well to accomidate race gas or to offset higher altitude riding by increasing compression. This is almost a must for anyone riding at 5000ft elevations or above.

That KX is going to be hoot to ride when you get it done Ski.
All great info guys, THANKS. You got that right Mo !! I will keep all that info on hand Ski but I doubt I could get it done over here. Our suitcases coming over and back are goin to raise a few eyebrows. LOL. They're gonna think I'm trying to ship back a parted out bike in our suitcases. Will an electric rattle gun work Ski ?? J/K... Again guys, great info.... Thanks...
"I want to die peacefully in my sleep like my grandfather, not screaming in terror like the passengers in his car."
ski, I think they wouldn't exactly have "All parts are all the same. " KX families are very different than KDX families. They update them quite often. Just look at the forks for example. Besides tube diameters. the internals are different.
You are right Jason. I think what I meant to say is that in the L series all the parts (major components) are interchangeable. Such as, forks from one year will fit any year in the series. Just about all the parts are the same part #'s according to buykawasaki.com.
Thanks for the correction.

No confusion here. I knew what you meant. The 2000 I believe were the first bladder fork in the KX's, the 2000 has a stronger conrod than the 99, different porting to the 99, jetting, etc etc... Oh and guess what ?!? The 00 KX's have shonky lower shock bearings too. Someone said they were replacing theirs 3 times a year, they're as bad as you CC. Thanks again Jason and Jerry.

Hey Fuz,
An earlier year (pre 99) first and second gear turns a 99-02 KX into a wide ratio tranny. I'm thinking about it. I'll need the gear shaft and the two gears. Anyone knowing of where I can find them, let me know.

That's awesome I'll keep my eye out....That era KX might just be my next bike The blue 250's will accept the WR's trans, but w/ some mild machine work. I'd rather it be a bolt-in job.
