OK, I blew my second 710N this weekend. They just can't handle the boost I'm putting out with the APR 93 coupled with the ECS N75. I don't want opinions of other DVs out there, so please don't post them. All I'm looking for is reports from people who have been running a Bailey for a while, say at least a year. I'm well aware of the specs of this valve and how it performs when the valve is operating properly. I'm simply curious if anyone has had to have theirs relubed or serviced? The fact that it is a piston type unit, but that it doesn't require regular lubing is both a comfort and somewhat unerving, above all it makes me speculate the long term life of the unit. I have heard nothing about the valves for some time, so I'm just womdering if anyone is still using them and with what degree of success. I know there were some that were sticking a few years ago. Is this still an issue as well? Thanks in advance.
