I have an 03 yz85, I run Mobil 4T Racing 10w 40 synthetic. About $10 a quart which is about average, you can find anywhere (even some Wal-Marts) and it works great. The Shell Rotella is really good too. Any synthetic 10w30 or better is fine, just change it often like after every race or after a weekend of just ridding.
