Hi all,
Been awhile since I posted here, mainly due to moving to CCR.
Anyway, got a friend who has just started diving and I recommend he get a G250v and MK25.
While in discussions with a well respected service tech, it was said that the piston bushes need to be cut before installed when a MK25 is serviced and a 2nd stage reg should not be used in the 5th ( bottom) port of a MK25 due to such hi flow rates which can cause pulsating IP.
I have serviced a few MK20's and 25's and never heard of cutting the bush nor is it mentioned in the service manual for the MK20 ( have not seen the service manual for the 25) I have also used the 5th port for 2nd stage regs with out issue and also not that the "DIR" set up for the back up 2nd stage uses the left posts MK25's 5th port.
Anyone care to comment?
