The Kral Puncher Empire X - Fitting a Robert Lane Regulator

In this video I show how to fit the Robert Lane Regulator to the Kral Puncher Empire X PCP rifle. This is the full tune, which means opening up the valve transfer port from 2mm to 2.8mm. The regulator can be fitted on its own without the transfer port being touched, and the regulator is set at 90 bar as standard, which would probably work well without the work to the valve transfer port.

If you go the full hog and do the valve, then you will have to be prepared to make adjustments to the valve spring pressure, as the power will increase once the valve port is opened up. By packing the valve spring, it makes the valve harder to open with the standard hammer spring, so the power comes back down to the correct levels. You may also need to adjust the hammer spring adjuster either way, and also the regulator pressure. This all takes time, but if done right you will benefit by lots more shots per charge.
The final set up with this rifle if you go the same route of the full tune is:

2.8mm transfer port of the valve. Three delrin washers, two of which come in the regulator kit. Set the regulator to 70 bar. Wind the hammer spring screw out by 1 & 1/4 turn. This gave me an average of 11.2 ft/lbs.

You can find out where and how to remove the anti tamper at this video link that I did:

This extractor and opposite way drill bit set can make removing the anti tamper snap off bolts a lot easier. By using the drill bit, you will find that the snap off bolts should unscrew, even without using the extractor bits:
