	Try searching. People have done it before and they also sell kits.

	Disassemble your valve. Use a #10 32 tap and tap the blowback hole just enough to show threads. Screw a standard cyclone banjo fitting screw into the blowback hole. It should get tight enough to break off before you see it on the other side. Grind it off flush, drill it .004 larger than your valve stem. Grind the small bump off your valve stem. Reassemble I do this for my Ebolted 98's and X7's and there's not enough blowback to feel. Without a regulator your FPS will jump up quite a lot.
