does anybody knows who can tune my rifle to shoot jsb a around 900 FPS mine it’s shooting around 960 FPS I tried but I can, i need a regulator tester.. anyway if anyone knows who can do it let me know.. thanks

Hammer screw can take it into the 800's it just would'nt be balanced,
My example was the same as your's I only adjusted the hammer,way more efficient in the 870 to 900 fps and plenty accurate ,kelly

I had a Kalibrgun Cricket Mini Carbine WST in .22
and I can confirm that with no other modifications, adjusting the hammer spring tension way down
can definitely put pellet velocities down into the 800 fps range. [I've done it with 16 & 18 grain JSBs]
I recorded where the 'oem adjustment' was set - For future reference If need be..
Then I removed the adjuster completely. From there, caught the threads, and started tightening..
I went 1/2, then 1/4 turns, and then fine tuned with 1/8 turns..
[I shoot indoors, so I'd rather have lower fps and higher shot counts]

BTW,
Should you still want to contact someone regarding 'tuning'...
I Highly Recommend Charlie at Georgia Airguns. This sort of thing is his specialty.
He buys, sells, services, tunes, etc.

Can’t tell where you live by your profile... You need to bump down the reg pressure about 20 bar, then tune with HST for 880 FPS. You’ll get many more shots per fill and better accuracy. If you don’t have a reg tester you can do it yourself without one(it’s doable but a pain) or buy a Huma that is marked with pressure and start about 120 bar. Easier but more expensive. Crickets are very easy to work on...

I did turn the hammer spring adjuster till it came out

Where did you get the gun from? Was it used? If so, I would start there & talk to previous owner about the reg press or any previous tuning.
Your spring may be stiffer than it needs to be. If non of this works as advice given above, then you would want to take the reg down a bit as per @centercut .
If you can’t or don’t want to work on gun yourself & you are closer to the SE, try giving Charlie from Georgia Airguns a call. I deal with him for my Crickets as I don’t have the time, tools, or time.

Eddy,
Gotcha. You definitely started off in the right direction then.
At that point, the only 2 options that I can think of would be:
- Lower the reg adjuster [as you mentioned]
Or
- Custom hammer spring [just to see what it could change]
Basically, try another one that has a lower compression rate..
Places like Fastenal used to be a good source for them..
I used to have to play with stuff like that all the time..
A softer spring will throw the hammer forward w/ less force,
so with less speed / force - it should let out a bit less air
when the valve opens.
Just a suggestion if you feel like experimenting / tinkering..

Sam - I bought this rifle more then 3 years ago, I was shooting jsb 18 gr at 913 FPS pellet on pellet at 40 yards.. Li two months ago I noticed loss on speed and accuracy.. I decided it’s time for a new reseal, so I sent it out.. I got it last Monday and start shooting, I was shooting great at 960fps I try to decrease the speed with the hammer spring but it just made like 20 to 30 FPS of difference the consistence was great only 6 FPS between high and low.. I leave in a residential area and only do back yard shooting , I don’t need to much power I try using a old hammer spring but it didn’t change anything.. yesterday opened and turn the regulator 1/2 of turn Dow but didn’t make any difference the only change is that now it is not accurate like before and the difference between the high and low shot is like 20 FPS or more I run out of air and also got tire of it lol

You need a real hammer adjuster, not just unscrew the cap!
Here for example
If you really want it much less powerful (half the original power or less), you just buy anothe hammer spring in any spring shop and you'll have plenty of adjusting possibilities.
But your goal should easily be achieved by the power adjuster alone.... Just replace the cap by the power adjuster and you're good to go

Eddy,
Right on man, thanks for the additional info.
Now that I / We know that the rifle was just recently serviced - The person who did the work could possibly have some helpful details for you.
I'd check with them and see if they did a regulator service/rebuild - and know what reg pressure they typically set to. [people tune differently]
You and I definitely don't need our rifles shooting that hot, that's for sure..
You mentioned that you adjusted your reg down about 1/2 turn..
I never had mine out, but, I like to watch people tinkering / tuning, so I found a few videos..
Ernest actually did a handful - removal / rebuild / tune / install / etc.
https://www.youtube.com/watch?v=IunugoDsIro
While he did have some specialty equipment - he also said that it's not needed, as following the method he uses here,
it'll set the reg to a very specific range. Right around 140 bar
This is a cool method / trick - then just adjust from there.. [internal regs are such a pain]
Me personally - I'd keep tinkering / adjusting - to see what changes can be done. I enjoy this type of thing though..
Oh the flip-side, I know how frustrating it can be! And then some!
I dealt with a really stubborn issue like this with one of my Taipans. FINALLY got it! haha

Thank you for sharing all this info I appreciate it..

Hi
I think the problem is in the spring, if it had an excess pressure in the regulator the spring would not have the force to open the valve and the speed would be lower, possibly where they had it repaired they had some problem with the spring and they installed another one too strong
Regards
Enkey

It could also be that the regulator was badly repaired and due to an excess of pressure it will shoot very loose and as a solution they will install a very strong spring

When I have time I take it apart and mesure the valve and the spring and compare them to the old ones. My problem will be to bring regulator back where it was before.. I contacted the person who did the service and told me that regulator it’s set to 115 bars also my gun has the power plenum installed..
