1. Is there a maintainance manual available for the WR.
2. What oil and how often does everyone change it, I do the 2 strokes gear oil once a monthor every 8 hours as a rule.
3. Weak points on these engines, how to prevent them and any cures available.

There is a manual available on his site, you have to get it and unzip the content.
High quality oil and if you race change it after each race. Regular oil and filter change intervals are every 1000 km (600 miles). But I think that most of the TT members change oil much more than what is prescribed in the book. Myself I change oil every 300 KM and filter on second oil change. I use Ipone S4.
Do a search on oil topic and you will get tons of info.
The weakest points on my bike are my two hands,
Seriously I'd say because of the small quantity of oil in the crankcase and the combination of high power output and high revs, frequent oil changes are a must.
You may have to learn the proper starting drill. But once you have it it won't make much difference.
Good luck and be prepare for a lot of wheeling fun

The week point on the 99 400 is the rear tire, for some reason the knobs just get wore down real quick, I cant figure it out. For real though, keep an eye on the rear spokes, they are known to come loose every few rides. The 98 had a week clutch basket. My 99 WR 400 has been an iron horse and been very reliable with very little maintanace, every thing I have done to it has been an upgrade or normal maint like brakes, tires, chain and sprockets, ect. I have beat the snot out of the bike too in the rocks and woods as Im known to do.

Funny but my hands are the weakest bit on my GasGas as well. ..I get 10mins in and have to peel my hands off the bars due to my forarms pumping up...10 minutes rest and I'm away until i can no longer hold onto the thing....but that first 10 minutes hurts...the rest is ACE

towards the 250F's, 99% of the info is applicable to your
400 as well.
i made up a page with links to the '03 manuals. again, while
not specific to your older 400, a lot of the info is exactly
finally, it's very probable that your linkage and steering stem
need to be regreased. i wrote up procedures for both items,
here are the posts.
