I'd call an anti-syphon tank a must, if you are using it "on-gun." Remote is a different story. I use a 20oz CO2 anti-syphon tank with an on/off valve. That is a little much b/c I also have an on/off on my KAPP DZ adapter. The on/off is nice b/c it let's you slowly gas up the gun. Gas up too fast and you might blow the electronics.
I just retimed my gun but I won't be able to test it untill next week. I do not imagine there will be any performance difference from on-gun or remote. Using the remote will make the beast MUCH lighter.
ok hall, if u have an anti siphon tank it is meant to be horizontal. using a remote puts it vertical. Vertical tank+anti-siphon=SIPHON!!! DO NOT DO IT!! you turn your anti siphon into siphon when u use remote!!!
Lube: there's the bolt, the fire poppet, and other things that the names escapes me right now. What was it.....for the whole gun you use about what....a quarter sized amount of lube? An amazing little amount
Timing: Pre 2k Shockers have switches that are on or off. My 2k 4x4 has 3 screws on the board that can be adjusted + or-. It's just a matter of turning a screw .05mm at a time and seeing how the gun performs.
The funny thing is, in the manual is stays it comes timed. Yes, but not very well. To get the best performance I had to adjust it myself.
