Many of the problems that occur with the One marker can be attributed to the stock LPR.
1. Inconsistant velocity. This can be caused by an unstable LPR. If the LPR isn't consistant, then the force driving the ram won't be consistant. If the ram isn't consistant, the valve won't open consistantly. Then you have velocity fluctuations.
2. Low velocity. If the LPR isn't flowing at a good rate, (even if the pressure is correctly set) the ram will starve for air, and barely open the valve, if at all.
3. Leaky solenoid valve. This happens when the solenoid vents excess pressure out the right side. If the regulator seat is leaking, it will allow the full pressure coming out of your inline reg to pass right through to your solenoid.
Rebuilding the stock LPR is very easy, and the parts can be obtained 24 hours in most cities. The stock LPR doesn't use a separate valve pin and reg seat like most others. This reg uses an automotive tire valve. You can find these at convenience stores, auto parts stores, bicycle shops, etc. You will need a valve tool (which is a small tube with a notch cut in the end of it) to remove the old stem and replace it. Some chrome valve caps have one of these molded on the top of them. Take a look at the tires on your car, you just might have 4 valve tools rolling around with you all the time. :laugh:
To replace the valve, unscrew the front portion of the stock LPR before the hose fitting. Look directly at the hex shaped section remaining on the marker. You will see a tiny pinhole that aligns with the hose fitting, and in the center you will see the valve. Using your valve tool, gently unscrew it and replace it with a new one. Screw the front part of the reg back on, and back the adjustment screw out a few turns. Gas up your marker, and adjust the LPR as you normally would. You're back in business. :D
Here is a photo, sorry about the poor quality.

The valve core is the part you need to remove and install in place of the old one in your LPR.
