B40 Tune up XS B28 Broken

Hey all, ya it's been years since I've been around.
Since getting hit with covid then getting killed twice by a heart attack I have been off work and playing with my AGs. Found out my B40 (.177) is only shooting around 620fps with RWS Superdome forgot to check the the CPLs. Pretty sure I was in the 700/800 fps or more range before. What kits do you all use these days. I tried the Vortek website but it's down for maintenance. I see Pyramid Air sells the PG3 kits for the AA TX200, I think I used this before. I am at high altitude (6,000 ASL) so I lose some power from that.
Also found my Xisco XS 28 does not catch when I cock it. I emailed Mike Melick he suggested oil and adjust and I am about to try that. I have not had an AG apart in years. Does anyone remember what trigger this gun uses and is there a diagram on how the sear locks and engages? I lost my hard drive with all my saved documents on AG repair.
Thanks for any help provided.
Mike

I generally get my tuning supplies and kits from Air Rifle Headquarters. I'm closer to 600 feet than 6000 and my TX 200 is just about 12 fpe, depending on pellet use. As far as your XS 28, I believe it has a Chinese clone of the T05 trigger. My first suggestion on your failure to cock is to back out the trigger adjustment screw a full turn or so. Also check for anything broken in the cocking linkage. If one of the cross pins breaks the gun may still go through the motions of cocking but the added slop can prevent it from latching. Both of these guns have a latching rod in the center of the piston.

Diagram for the XS28 attached to this message.
Tuned my B40 some time back and used a Vortek P2 or P3 kit with ARH piston seals:

Looks like the end of the safety busted off and jammed up in the sear catch area. Now I need to find a new safety or just replace the whole assembly. I'll email Mike Melick maybe he sells the whole assembly already tuned and modded. Does anyone know if there are other resources?

Your best bet may be to contact Diana directly and request the part. Here is a listing I found that may work for you:

Let us know how this works out for you. There are a number of us with similar rifles that will be needing parts sometime in the future.

Your best bet for XS-28 parts would indeed be Mike at Flying Dragon. He could probably sell you a complete trigger package for what Diana would want for the safety lever. Who knows? He may be able to sell just the part, not the whole assembly. I've found his parts prices very reasonable and he's quick to respond.

Mike is going to send me a new safety. I guess time to clean and polish while it's apart.
