So I install my super cool... almost like new... bad to the bone pop-off valve... I give her a try with the shop air regulated down and it works killer. Up and down... up and down... I'm stoked right. I hook it up to the co2 bottle and I get about 1 1/2 cycles out of it and she's out of wind. So my question is... anyone else running a smaller than the 2.5 lb bottle for thier pop-off valve... like a 10oz? If so... how many cycles do you get out of it? I'm hoping that dude that refilled the bottle just chumped me and didn't fill it all the way... it had about 750psi in it to start.
