Some people you just can’t help.

There’s a recent thread about this in the general section on setting up a 760 with b pipe, I think we decided start at 125 low and 115 high 24 psi pop off

People call it reverse jetting but reality it’s just jetting. Set the low speed jet where the bottom end runs the best then set the high speed up for best top end pull and if the low speed jet is bigger than the high speed then that’s just how it is. @TehXshizzit On the b pipe, close top 2...

They are pro x, I was thinking the same thing. I usually just put new ones in every year. I also thought people would like to see the porting before they buy it. I am going to re-assemble it tonight. @MTRHEAD did the case work.

Is the footrocket really very freestyle? Seemed kind of heavy the one I seen and I didn’t get to ride it yet. I hear they are good in surf
