B2K malfunction

Hi guys, new to nation here and looking for some advice. So I decided to bust out my guns last weekend and play with some friends after several years. I hooked up my B2k, shot some air thru it...perfection. Put a hopper on, tried to throw some paint and it just stacked ball after ball in the barrel. The gauges read fine but its like its losing pressure as soon as i put paint threw it. any suggestions? (ive cleaned the gun, changed o-rings, regulator seems fine) thanks for any input here. use to be a great gun and id love to get it shooting again.

some lubes especially factory ICD reg grease turns hard yellow after a while. I picked up a pretty much new FS8 a couple months ago that had never been re-greased or used much, just sat in a closet. The HPR piston o-ring was hard as a rock and fell a part when I changed it. The LPR o-ring was ok, but lube was almost lumpy and waayyy too thick. New o-rings in both with fresh grease and it shot like butter.

I would also clean your ram up. Thick grease on it will slow it enough to not hit the valve. If I remember on my old b2k didn't like grease on its ram. I used some slick honey with oil mixed in to thin it down.

when cleaning are you just wiping away crude or are you taking everything apart and then relubing it?

in the regs, the piston is that big fat disk that the spring rides on. its the same in the HPR. the ram is the black thing that screws into the bottom tube right above your hand. it's also where the bolt pin connects to.


that is the LPR piston


that is a completely apart ram

also, if you can get a pic of your gun, we can see what you have and use your own gun to help you. plus, everyone like gun porn...

ok so i had the lpr, hpr, and ram correct...thats a start i have cleaned and re-lubed. my friend also took the gun apart, put new o-rings and said all looked fine. once again shot fine with only air but put paint in a hopper and very little air pressure (not enough to shoot paint. It just seems weird that it shoots fine till you put paint thru it. I will upload pictures asap. my camera is broke but ill borrow one. I also have a 03 bobby long (works great) and a 02 dark angel (need board...good luck) in the market for new gun if i decide to commit to this. thanks for help again guys and ill upload pics asap

There she is, all broke n sh*t



There is the LPR (can't get that piston out) how? do i take off the pressure gauge and unscrew the top half as well?




There is the HPR (i think) comes out from under the barrel



Here is the same photo with an o-ring off that doesn't fit very tightly where the arrow is pointed (sexy artwork i know)

This is as far as my ram comes apart unless im missing something. Am i missing something here? your picture shows a fat o-ring at the far left side, mine doesn't have that.




Bottom pic of the bolt.




Top pic of the bolt.

You can view all pictures at http://photobucket.com/kevsbush

once again thanks for your helps guys. I'd really like to get this gun shooting again even though i am buying a new gun. any tips on how/if to take apart that ram/lpr piston please inform me.

1) the LPR(low pressure reg) comes from under the barrel and HPR(high pressure reg) is in front of the grip frame.

2) from my pic, some have gone a step further and installed a hammer bumper(which is the oring on the left of the pics i shown), after breaking the red loctite holding the hammer to the ram shaft. you don't have to do this, unless you want to get into polishing and a lot of DIY mods.

3) LPR: follow this tutorial on how to take apart and service the LPR.

4) HPR: taking apart the top part is difficult. not a crazy skilled job, but hard to do without marring or making idiot marks on the reg. follow this tutorial.

5) finally, follow this tutorial for the ram.

6) after putting the regs and ram back together, its now onto the "idiot" type checks, because we've all made them, so its no slight upon you.

6.1 make sure that the hole on the bolt is down.
6.2 make sure that the bolt pin is riding in the ram properly(you want it in the slot)
6.3 make sure that you have a good fresh battery
6.4 make sure that you have air in the HPA tank

7) after all of that, wake you way over to ICDO. we hang out there(only visit here) and are more apt and more readily answer questions there. not to say that PBN is bad or anything, there is a wealth of info here, but its just easier over there.

8) contact me for the frame mod and a new harness.

no. the one thing that owners of ICD guns will do is, mod like crazy. the platform lends itself to it as well as the lack of aftermarket parts dictates it. so there are plenty of people that do P&P(port & polish) mods on the ram or LPR. my own frame mod(makes putting in and taking out the microswitch much easier), detent mods, cutting the bolt, etc. so if a pic has something that you might not have, it isn't a bad thing. plus, there is hardly a stock gun anymore, so we have had 12+ years of modding. i have guns that hardly have stock parts anymore.

I would say you just need to lube the lpr, hpr and cylinder. Put a new battery in it and you should be good to go.
