Thank you for the kind words. The sleeves can be removed and replaced, I forgot to do it for the video though, oops! I documented the process of removing them a little better in this video on the M3010 series, kzfaq.info/get/bejne/q6eBrbuisZ61ZHk.html just skip ahead to the 3:00 minute mark and the same technique applies to the XCT!

@@crossedhelix8698 Cheers buddy. keep up the good work! =)

It's best to open the lockout so that it moves freely, but you can still take it apart with the lockout engaged! You can stick a hex key in there to adjust the lockout once you've removed the cap if it becomes an issue

It looks like if you have an XCT LO model, there are soft, medium and firm springs for sale on SR Suntours site, but I haven't been able to find any direct aftermarket springs for this particular model. I'm sure there are some out there that fit, but it might take a little experimentation to find one that matches up well!

A pop filter dosent do this

That was a can of Mobile 1 Synthetic grease, Its super inexpensive and very tacky which is why I like to use it!

If you’re talking about mt200 shimano hydraulic brakes, then yes, that’s what I have on this fork

there is plenty on Thingiverse

It's been difficult to get typical pricing lately, but these cartridges can be bought for about $40 dollars or so right now on SRSuntours main site. I'm not 100% about the fitment, but they have some on ali express for $30 or so dollars too.

Don't know if this is still relevant to you, but I will explain it anyway. Also I don't know your experience level, so I will go rather detailed. There are some variants of this fork. Some have two steel springs inside some have a spring and a dampener (the part you indicated), but both tubes should be populated by either of the two. A dampener basically is used for slowing down the speed that the spring contracts and extends with, e.g. through increased friction or flow of a liquid through a tiny opening (there are many ways to achieve this, some rather simple, others more complex). It also takes energy out of the system, which means if your spring was oscillating, with each oscillation the dampener would take out a bit of energy and translate it to heat, making the next oscillation cycle a little shorter in length. Actually on suntour's webiste you can find the construction plans of those forks including the part numbers of individual parts. Make sure that the name of your fork matches with the name of the fork specified in the document. Be careful: a comma used in the name in the document might indicate that the document specifies 2 slightly different forks. e.g. the document for the "SF16-XCT-DS-HLO-29-80,100" specifies two similar forks with 80mm travel on one and 100mm travel on the other fork, thus the name of your exact fork will either end on 80 or 100, but not both, eg: SF16 XCT DS HLO 29 T 100 (that's what might be written on the fork somewhere). Variations in the parts can depend on the exact model of the fork, the wheel size... For the fork named above, intended for a 29 inch wheel, the number for the dampener would be FUN050-14 (don't ask me how they came up with that part number😂). The parts can be found online for sale.
