what do you guys know about this bike? good and bad. from my understanding 99 was the year yamaha redid the motor on it. i might pick one up tomorrow. guy wants 800 and he bought it from the original owner in 08. hes 47 and only rode it twice a year on trails and the rest of the time he kept it in a storage container. rebuilt carb last year. i mean for 800 why not. just kinda looking for pros and cons on the bike. thanks all

Buy it! Pretty simple. If you can track it back to the original owner you are gold

yeah thats a big selling point in my book. and the fact the the second owner was damn near half a century old and rode it twice a year. but i was talking about that bike in general

I picked one up in pretty decent shape about 2 yrs ago. Rode it for a bit, it's been sitting ever since. I really want to rebuild it completely. The motor IMO was strong off the bottom, my other bike is a 09 ktm 150sx and compared to that it felt a little heavy and kinda wide in the rear. Other than that I liked the power a lot.

I would also be interested in the pros and cons of the 99yz250..
Seems like it was quite a good bike at the time.

Is there any chance that vitals resident '99 YZ250 expert DV12 could give us the run down?



Was the 99 a new motor from 98?

What was the frame like? Did they develop the steel frame much from 99 till they went alloy?

Forks? Good / Bad?


Cheers !

just a little update.. just got home with the bike not too long ago. excited to see it had excel rims! bike is pretty clean, just needs a nice detailing. only thing is the forks were sprung for a 230 pound rider and im 170. first thing i noticed from the little test ride down the street is it has alot of bottom end power. feels like alot more then my 03 rm250. i didnt really get on it since it was pouring out, just clicked though all the gears so i dont have anything to say on top end power. gonna take this and the RM to the track soon and see what i like better and sell the other. my plans with the yz if i keep it is seeing about updating to 06 and up yz250 speed sensitive forks if theyll just bolt on. 2011 yz450f front fender and number plate and shaving down the side number plates to give it a more modern look. new graphics too.

Is that a white airbox or a sticker?
If its a white airbox you have scored yourself at least a 200 model im pretty sure.

it is a white airbox. and while i was looking it over the date on the vin was 12/99. does that mean it could actually be a 2000? cause i know on carsif it was made in the later months its normally the next years model

2001 models had the white airbox and the front fender and number plate were a little different.

If it was made in 99 and has the white air box I bet it's a 2000. Did you get a title? I have a 2000 yz 250 and it's a nice bike. I put a 9 oz fly wheel weight on it and the power is much smoother. It worked really good for me. I have heard you can bolt on the SS forks pretty easily if you just get the matching triple clamps to go with them. I think I read on thumpertalk about someone doing it.

Yep pretty sure you have yourself a 2000 model. Nice.

that sweet! thanks for the heads up on it being a 2000!

I own a 99 mod and can say with 100% certainty that white airboxes came in 2000.
Also, the trippleclamps were different with a new front numberplate mount. So check out if the plate is fastened without modification if you are unsure. I could not mount the 2000 mod plates on to stock 99 without some tinkering.

BTW, good choice of bike! smile

Any YZ250 from 99+ is really good.

The engine was new in 1999 and is basically the same through 2013.
In 2002 they added the 5mm spacer between the reed block and cylinder.
They changed the ratio of 2nd gear (to a faster gear) as well as bumped the compression ratio up and raised the exhaust port in the 2003-2010 models.

My 99 was a solid bike. With a FMF fatty and Boyesen rad valve it had tons of low end torque.
A bit outdated by now (single chamber fork for example) but unless you plan on racing, you can'g go wrong as a solid, easy to maintain play bike.

If Im not mistaken, didnt both the 2000 and 2001 get a white airbox? I had a 99 and the airbox was black.

first off, that is a beautiful bike and should be in the kickass two strokes thread if it isnt already. second what plug do you run? it has a ngk br8eix or whatever the iridium plug is. does it take normal br8eg's?

I ran A B7ES plug in the woods on my 2000 and I went with 1 size smaller on the pilot jet from stock and I don't think I ever fouled a plug..

Thanks, since I'm slow the least I can do is have a nice bike :-)
I don't have it anymore, so I can't tell you about the plug. But I was probably just running whatever Yamaha suggested at the time. I have found that with a properly jetted bike I never foul plugs.

for me it seems like everybike ive owned, however the jetting was i could go though a plug in an hour if im riding trails, but if im on a track theyll last till the next time i go for a trail ride lol. but ive always ran my bikes on the rich side whistling
