Longevity of the WR400's

My problems have included 3 carb-slide plates fracturing and being injested by the engine (check your throttle stops!), bent frame rails, trashed the linkage and swingarm (check your lubrication in your bearings!) and my fork seals give me fits sometimes.
I would conservatively guess that I have 15,000 miles on my bike. Still on the original set of rings (will be replacing those next time I go in) and the bike still rips.
Great bikes, no doubt about it.

my son's 98wr4 have been reliable as anything except for the carb slide,
get aftermarket ones and they shld last a long time,
a fren helped us to adjust the valves after abt 2 yrs of use,

No idea how many miles are on it, I've put 1400 in the last 3 years (not a lot)...

It doesnt get used too much but when it does I thrash it and it never complains.
Things I have busted....many.
Things tha have busted on their own...carb slide, rear light bulb many times!
Throttle cable wears prematurely
......I'm hunting for bad things to say..

Only problem I ever had was a slightly twisted cam journal from, I presume, riding the bike on the highway @ 65+ and riding in cold <30 deg weather.
Other than that....Bwaaappp....

Typical replacements include a few bearrings here and there (steering head, 2 in the swingarm and the bottom hyme-ball bearring for shock). Front fork seals blow only because sometimes I'm too lazy to clean them off after muddy rides. Replaced clutch cable. I've checked valves several times each year and they haven't budged.
I've crashed numerous times and tweaked the radiators, but after installing DeVol radiator guards they've been indestructable. MSR Skidplate has been a wise investment. I put a hole through the side cover on a rock in the first year. Ever since installing the skidplate, nothing touches the shifter, rear brake lever nor sidecovers.
I grew up riding XR's in which I never did any maintenance outside of air filters and oil. They were bullet proof. The WR's I've owned (also owned 01 WR250F) have proven themselves to be very reliable and have superb longevity.

Last year I picked up a 99 WR and have been using it to run the D37 BOTW and enduro series. This bike takes a pretty good beating every time I race it and I’ve been monitoring things like compression and valve clearance following each race very closely. So far, none of the engine specs have changed significantly. I’ve found that if you stay on top of the routine maintenance, these bikes (like most stuff these days) are good for several years of trouble free hard riding/racing.
One last thought, since The Peoples Republic of Kalifornia no longer allows dual sport conversions, I plan on hanging on to both of these bikes (both are plated) for many more years and I have a lot of confidence I’ll be able to keep both bikes in race ready condition for many years to come. My 2¢.
