Try for 400° F (head temps with a trail tech temperature gauge nothing else used as a gauge) or less no matter what conditions: full throttle for five minutes uphill for five minutes 100f air temps .
So many people say my bike runs 350° Blah blah but yeah they only hold it down for one block. hold the throttle pinned for five minutes then see what the head temps are or go up two mile long uphill and see.
