When I saw that the temps were high I richened the high about an hour and had very noticeable loss in performance so I leaned back out.

I had about 1/2 gal through the motor before the race. Is the high temps normal for this mil? I had to send this motor in for repairs under warranty and just got it back with a new piston/sleeve. I did break in by the book.

Should I be worried about the temps? or just I continue to tune for performance? Any opinions would be great!!
