Unless the temp is over 100. Don't worry bout over heating. If you're running knobbies, i'd say run about 4 PSI. I run 5 or 6 in my paddles. Goin up hills? Hit the whoops as fast as you can and lean way back. If you slow up, the whoops will take your ass. Keep leanin back on the way up to keep traction in the rear. If you racing up the hill, try starting in 2nd and rev the shit out of it before you drop the clutch. Stock swingarm? lean forward at the start so you don't loop it.
