New PCP user, looking for Bullboss info

Hey folks, I finally jumped into the PCP world with a Bullboss in .25. I intend to use it primarily for varmint control. While I've built, upgraded, and maintained firearms for years this is my first PCP and frankly the factory info on the Bullboss is lacking. I see a lot of random info on YouTube, etc, but are any of you aware of a decent publication or website for all things a person might want to do to a Bullboss? Thinking disassembly/assembly, hammer spring adjustment, regulator installation, etc. My little brochure that came with describes the trigger adjustment basics, but that's about it.
