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!!
I never use a temp gun. I tune on trail of smoke and performance. Too many things can go wrong with temp gun and trying to tune by temp. I see to many guys take a perfectly running engine and move the needled because of some temp. I would suggest you use the "old school" method. Put a drop of water on the head or spit test. The properties of water will always be the same. Too many variables to tune by temp. Hope this helps.
