ok guys there is a local YZ400 i have a chance to buy. Give me some insight on the bike? Im the owner of a XR650R and CRF450R. So how will the YZ be for trails, and some dirt roads? Will the transmition be just like my CRF is, geared super low? The guy is asking $1200 which seams resonable. I was looking for a 2 stroke, but im not so sure. How will this stack up against a 250 2 stroke?

What do i need to look out for? any problems with these bikes? Its the first year bike yes? must have been some kinda quirks?

You could pick up a 2002-2003 yz250 for that price, and you can rebuild the top ends for under 200 bucks and about 2 hours of your time. Four strokes cost about 1500 bucks to have the top ends rebuilt.

the old 400's were fast bikes (faster than most 250 2T), the suspension will not be as up-to-date are your CRF, but it will definitly handle the trails...(offer him $1000)

It's a good trail bike and even a weekend racer. Not as new as your CRF but definitely in the same ballpark.

$1200 seems a bit high for a bike that old though. I'd offer the guy $800 and go as high as $1000. Your probably going to need a valve adjustment (or even some replaced). Might as well put in a new piston while your at it (cam chain too).

Water pump seals and fork seals will probably also need some attention if not now, soon.

2 strokes around me are super expensive!!! To find something for a grand i have to look at 80's or early 90's! anything 2000 and newer are atleast 1500 if not 2 grand +.

Ive rebiult 4 strokes before and it only cost me $250...you must be talking about valves in a cam to. In my expirience those last a lot longer than the piston and rings. NADA value on the bike is 1100-1500

As I recall there were a few changes from 98 to 99 and my 99 was stone reliable. See if you can find some old magazine tests for the 99 as they usually tell what was changed and why.

we have both a 98 and three 99's at my house and the differences were extremely minor. like the hot start knob on 98's were black and red on 99's. the little dust caps on the rear hub are the same width unlike 98's which are different. the hub is different. little things like that.
