What the heck happened? One day the low is in the 70's the next it's in the 40's...us Desert Rats don't like that
I have gone up Mt. Lemon, and A Mt. with the 36 & 44 and many other hill's. The 44t does much better.
As far as longevity, I've got 5 years and well over 4,000 miles on my China girl. I think more has to do with how hard you ride and push your motor. If you are running wide open all the time your motor just won't last as long.
