Hello Tyrone, greetings from Serbia, out shooting the other day and realized -5 celzius was too cold as the cp2 mechanics froze due to cold gassing of the capsule, so i pulled the thing appart amd analyzed the internals carefully, i think i will widen the port somewhat and install a lower force spring on the valve, still have to find the proper lowerf force spring for the valve amd greater force spring for the hammer, this video of cp1 tuning is really nice. I really started to enjoy this little marvel.
Hi, glad you enjoyed the video. Yes the co2 doesn't like the cold, it is the biggest negative to co2. If you open the ports just remember everything must be balanaced, sometimes you need to open the ports and increase hammer spring tension
Hello! Have you ever attempted the bstanley o-ring buffer mod? from the posts i have seen it seems to be simple and it increases the amount of shots significantly.
@African-Budget-Pellet-Gunner You basically need to fit a few o-rings between the valve and the hammer. They are supposed to reduce hammer bounce as the pressure slowly drops.
There is a general misconception with moly grease - its purpose is a non-stick surface coating to prevent seizing in high pressure joints. It is an anti-seize compound. It is not a good lubricant. The spring might be better lubricated with a mineral gun oil with maybe a thin smear of lithium grease (LM) on the ends (not the white muck). Oiling the body of the spring is mainly to prevent corrosion.
It provides wear resistance and reduces the friction coefficient of steel on steel even after being wiped off. Molybdenum disulfide bonds to and fills micro surface roughness in steel alloys.
Thanks Jeff, on the PCP or CO2 guns I don't usually lubricate the whole spring but just the ends. I want it to function kind of like a top hat on a springer. Just allowing the spring to rotate freely in the hammer. Definitely that torque movement is significantly reduced with the method I have used
I haven't experienced this on any of my guns and I have been using sewing machine oil on my o-rings for many many years. What would you recommend instead?
Hi Kobus, I did measure before and after on the CP2 but not on the CP1. They should be very very similar though because the only actual difference is the barrel length, otherwise they are basically the same internally
My CZ200S has been cleaned and lubed with Ballistol only for 18+ years and I have yet to replace an o-ring. This was more a result of what I had on hand, and what I have been using on rim, and centre fire rifles and handguns for many years. On all my newer rifles I use silicone oil on the o-rings and this is what I would recommend as well.
@@African-Budget-Pellet-Gunner I shared it only because I doubt it will do any harm if already used, not necessarily because I still believe it is the best for o-rings, these days I also use silicone oil for o-rings.
Thanks for your useful information Tyrone ！Happy new year to you and your family ！🎉🎉😊
Thanks KLee, compliments to you and the family as well

Happy new year sir cheers from u k
Thanks Winston, same on your end. Thanks for leaving a comment
Hello!

Hi there, nope I have never tried that mod before, tell me more, how does it work
@African-Budget-Pellet-Gunner You basically need to fit a few o-rings between the valve and the hammer. They are supposed to reduce hammer bounce as the pressure slowly drops.
Oh ok, I have heard of it but haven't tried it. Probably something I should look into Thanks

Mineral oil will kill his o-rings.

Thanks yip it is working well. The spring is turning nicely within the hammer without catching so serving it's purpose.

Have you measured a shot string before, and after the tuning exercise Tyrone?
Hi Kobus, I did measure before and after on the CP2 but not on the CP1. They should be very very similar though because the only actual difference is the barrel length, otherwise they are basically the same internally
Can one use Ballistol inside CO2 guns ?
I would probably not recommend it on o-rings and seals. It is great though on the outside, barrel breech etc, it creates a good anti-corrosion layer

@KolaDiver Thanks sharing your experience, I guess ballistic can be used internally then
