Questions On Yamaha WR400 Modifications

Many thanks these questions are for a friend looking to buy a used WR400 model, anything to note to look for as a weakness or defect in these models?

I changed the oil every third ride and the filter every third oil change. You can buy the stainless steel filter that you can clean and re-use for about $70.00 US.
I actually liked my 400 more than my 450 as far as ease of maintenance and certain performance aspects. I still own the 400 and will actually race it from time to time at the closed course events where it's tighter and more MX oriented.

i pulled my head off yesterday and found the valves to be fine, there was slight carbon build up but they were not worn at all
change the oil heaps, and keep the filter clean. they're good bikes
