I have a set of TEKTRO ORION 4pots that I'm looking to mount on my dirtjumper, they have served me well on the trail bike with no issues but I've had absolutely no luck getting them to work on the jump bike, I've bled them a bunch of times and air seems to keep making its way in bc it always spews out a bunch of air bubbles before any oil comes out, I've checked all the hoses and interfaces and everything's tight and doesn't seem to have leaks, any ideas

have you tried a total flush of the system? Could try forcing fluid through until you feel you've pushed all the old and some new out. Also tapped on caliper pistons both sides and wiggling hose can often find trapped air.

Take them off the bike and hang them with the lever up and caliper down then bleed them. Be careful to get all the air out of the fluid as well before you start bleeding.

If that doesn't work you may have a bad seal somewhere.

I'd like to add, pull off the rubber cover for the hose nut at the lever and see if any oil has been leaking out of there. Sometimes when you transfer brakes from an internally routed bike the olive and barb do get seated back in fully/correctly.

And another thing that helps dislodge tiny air bubbles is to use something that vibrates (hair clippers, electric shaver, toothbrush) along the hoses and the caliper too.

I bought a MRP progressive spring and I’m waiting for the spacers to show up for my super deluxe but when I put the spring on the shock it fits fine there is no side to side play and I still have lots of threads left ... do I still need the spacers ?

An MRP spring is almost the same diameter as an RS spring. You shouldn't need any adaptors.

ETA - I have run RS springs on an MRP Hazard with no issue.

I've done a few Lyrik lower leg services, always according to the SRAM video. I note that this document (https://www.sram.com/globalassets/document-hierarchy/service-manuals/rockshox/front-suspension/gen.0000000005952-2020-fs-oil-air-coil-token-specification-english-rev-a.pdf) says 3ml of oil in "upper tube". This doesn't seem to be shown in the video. Does this mean on top of the air spring, under the valve?
