very often! I put two hours of run time, but I would expect that oil had no more than one hour on it. That's about one race day. thanks for above comments... (and the owner of this bike insists on mobil....so he runs it). Any suggestions for a better oil? I have actually been reading sunruh's...

not stating oil performed poorly, I truly don't know much about oil analysis, but the motor looks to be experiencing significant wear.

sorry.. motocross water cooled single 250cc nikasil coated aluminum cylinder

leaded race fuel used. Engine has in excess of 50 hours, and is raced at a local professional level. Engine shares transmission with engine oil. Doesn't look good!
