I did my first race back in awhile this weekend. I was revving the bike a little more than usual since it was a race no taking it easy... I finished practice and emptied that Head cover overflow tube that splits to the airbox and oil ran out a lot. Not the normal 2-3 drops. The same thing happened after the following two motos. Each race was 20 minutes plus one lap. Is this of concern or normal for race conditions? racing conditions were sunny 70 degrees and i raced 450 pro... thanks guys!
