any one else run nitrogen in your tires? i use it in my xr650l, my wifes shadow, and both our toyota's. we have a fill station at our shop and it is killer stuff. 1: it doesnt fluctuate in PSI with temp change. 2: it has larger molecules so it doesnt leak out like conventional shop air. i just checked my tires after 3 mths. (i know this is a bad practice!) and the tires were still at 21 pounds like when i first filled them. good stuff!
