I just bought a WR400 about 2 months ago used. After I purchased the bike I had to redo the seals and other miscellaneous stuff to get the bike up to par. Nick at Pro Valve in Costa Mesa, Ca gave the bike an A-Okay after replacing the seals etc. The question is: Is this a trustworthy bike to take on long rides into the desert? Was 99 a good year for this model? How long do the motors last on these bikes? I know the previous owner probably put around 5000+ miles on the bike.
