Or put some kind of thin gasket(s) or spacer(s) between the 15,8 mm bushing and the linkage..

I would buy a cheaper 15,8 mm bushing and put electric tape between it and and the linkage/frame to get the bike built. Then wait for 16 mm reasonable priced bushings to be back in stock..

I first had a 2.4 Kenda Booster Pro in the rear (28mm inner width rim). The seat stays have a lot of room but chain stays are quite narrow. In dry conditions it works ok, but I wouldn´t do long extra muddy rides. Now I have a 2.35 Renegade Control T5 and it fits much better in the chain stays.

I have been waiting for the second warranty front triangle from Airwolf for 3,5 months now.
3 months a go I was told that the frame is on painting. (nothing fancy, black glossy should be ready by now)
Airwolf customer service has been the most frustrating service ever. The only way to get a contact is to use the chat on their web page. If I use my main pc and browser and ask with my own name, the chat doesn´t work: I get no answers. If I use another pc in incognito mode and ask something about other products without my name, the chat starts working and I get a contact. Last time I got a contact a few weeks a go and asked about the warranty front triangle. The answer was: "This one have´t sent to you?" and then nothing else, NO NOTHING. I put my e-mail address and phone number in the chat so they could contact me better, but no messages have been received. I have been thinking if I should use a VPN to make their chat work better.
In common I have nothing against BSA. An SPcycle M05 I assembled for my friend has more than 10000 kilometers in its bottom bracket insert and it just works.
On the other hand the Epic clone has been frustrating. First front triangle lasted about 10 months (5 of them the bike was not ridden in the winter) before drive side bb insert got loose. The second front triangle lasted less than 300 kilometers before left side insert got loose.
My solution has been to buy other frames: TanTan 121 and Hongfu 138.

Hello!
Can I ask about the frame? When did you buy it?

I bought this frame just because of PF92!
BSA can ruin your summer
. I have owned a BSA frame that has more than 10000 kilometers and a frame that lasted less than 300.

I have 30mm Race Face cranks so I can´t say about Shimano width. If you have or can buy thin 24mm spacers for Shimano axle, it is easier to adjust the chainline and width when the spacers are outside of the bottom bracket cups though.

I have had squeaky pivots too and in the beginning bolts could come loose in the middle of the ride: not good. The best method so far has been putting grease (NLG1) on every bolt, bearing and bushing surface and blue thread lock compound on every bolt thread.

I used (look at the pictures above)
seat stays: black glossy car wrap (can not be seen in the pictures above, same color as frame)
chain stays: a thin layer of white material (the frame is wrapped with when it comes) on top of chain stay and black electrician tape (not the prittiest but it works)
seat tube: basic duck tape
down tube: Gorilla tape
top tube: car stone chip film, see through

Do you have a lot of experience in painting? A year a go I painted my first aluminum frame.
The best information I found came from this YouTube channel:

I like the rear suspension a lot. I have a Float DPS. The rear suspension works almost as well as RM Element´s. I ride with the setting in the middle position most of the time because the suspension is so active and soft.

Hi
On all the bikes I have ever serviced or assembled the lower bearing has been the bigger one. Usually the diameter is also smaller on top, but these straight tubers have the same diameter. I can´t disassemble the FM121 now because of work, but i think the lower is bigger.
One side of the bearing has curved edge and the other side is flat. The curve side goes towards the frame.

My freshly built FM138. I like to create funny bike brands. This is first POMP (bounce, boing, jump). My second Epic Clone front triangle lasted less than 300 kilometers, so I ordered this to save the coming summer. Sometimes PF92 may be a good choice. Most of the parts are from Epic Clone. I may have to buy more Pirelli tires now..

I found that the rear shock bolts on Epic clone are not the most durable hardware. Ordered these for the linkage when the bolt broke:
