the rule of thumb is as long as its over 100 psi and they are with in 10lbs of each other the top end still haves some life in it. Thats stock. Now if your head isnt stock then that all depends. It also depends on your location.

i think 10lb of is way to much,and the bike will run poorly. :blink: :shrug:
