Classic with an X-valve ?

[RevBrown]

What would cause my x-valve to not charge the trigger at all
I am also having trouble with chuffing.
My local mag wiz says my chuffing problem is in my level ten but why does it not charge itself sometimes?

What's your input pressure and velocity?

[RevBrown]

750 but I was told that was fine


oh and I was shooting around 265-275

[RevBrown]

I think I got it

I just went down to a shorter spring and went up on my spacers.
It is charging just fine now and I can rock on the trigger without hearing *spussh* every couple of shots
Course I may be full of poopy cause it has been kinda tempermental today.

i was having the same problem as u were on my classic with the x-valve alls i did to it was start shootin a 800 psi and 275-290 fps and now i have no problems also i did change the spring out so now it woks good for me so good luck......

[RevBrown]

I was actually told by the local mag guru that 900 was even better.
Can anyone confirm this?

between 700-900 personaly i think is good for the x-valve
