The key point in your method is "the old school", so many things have changed, for the better since the "good old days". Better oil, better metallurgy, better manufacturing even on our 20 year old DRs.
Syntetic oils didn't hit the market until the late 60's. When you think about it, the DR engine has more in common with a late 60's VW engine than anything I can think of on the market today. That old school thought process still applies well to quite a few "modern" dirtbike engines.
