My buddy and my daughter both race a '09 KFX450R quad in a local XC series. At the last race, they both ran the same amount of practice and raced on the track at the same time. So we figured it would be interesting to take oil samples and compare. I was running Elf Pro-Tech 5w40 and he ran Amsoil 20w50 motorcycle oil. He doesn't have his results back yet; these are from my quad:
Terrible, I know. The engine has been raced it's entire life, 77 hrs, and may be showing that it's time for a complete rebuild.
I'll post up my buddies results when he gets them back. In the interest of full disclosure, he hasn't mailed them yet.
