I’ve seen the stuck bead before on an oem fitment.  Once the bead has been broken the first time it seems to be ok which is strange.  Struggling trailside to break the bead but once broken the tyre comes off easily

You need to set the limit screws before you end up with big problems like the chain coming over the top and going into the wheel.  Treat Eagle exactly the same as any other in terms of set up, it’s just very sensitive to set up if you want it to work smoothly.  The Sram website has a very good instructional pdf to follow.

My Eagle chain is very worn (I left it too long and a new chain won’t work with the old cassette now) but still shifts perfectly so I doubt its that causing the bad shifts.

Maybe a bit of research into basic nutrition would be helpful as it seems that you clearly lack any knowledge on the subject (no offence intended).  You have been given a lot of great advice here and with a little bit of planning and will power, you will be on the right track in no time.  You only “need” all of the sugar because you eat the sugar in the first place. Kick starting your day with a sugary breakfast and the vicious cycle starts.  Fixing your shocking diet will transform the way you feel, and your rides and recovery will be much better.  Good luck with it.

There is definitely slack there on the GX Eagle mechs that I have had.

I had this with my Pikes. Pump up to max pressure and cycle the forks a few times.  The high pressure should shift any grease out of the port.  Do the zip tie burp again with the forks at full extension.  I also have the 2019 shaft and they sit only very slightly into the travel.

I got given a bottle of uberbike sealant by a friend who said it was useless…..I have set up a new Maxxis Aggressor and it sealed fine.  When I took it off you could see the fibres bunched together in a couple of places around the bead where it had sealed.  So I tried it with a worn and cut up Minion.  It started out leaking like a sieve all around the sidewalls and several places in the tread.  10 minutes later after spinning the wheel in the work stand and its stayed up for 2 weeks with no pressure loss.  I’ll be getting another bottle at the price they sell it for
