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
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 !

If its a white airbox you have scored yourself at least a 200 model im pretty sure.
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!
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.
A bit outdated by now (single chamber fork for example) but unless you plan on racing, you can'g go wrong as a solid, easy to maintain play bike.

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.
