WTF is going on? New(ish) 819 & an old but good Mud-X, lots of stans fluid and the tyre is sitting happily on the rim - looks fine all the way around both sides. No fluid coming out of anywhere but the bugger is going down in a couple of hours?

Thoughts?

Was kinda getting to like this tubeless malarky now I have a compressor, but rapidly going off it.

hmm use a low tech solution like that, pah not likely, is there no specialist tool that costs the earth I could buy instead?

<runs off to fill a bowl of water>

... I just expect the stans fluid to come out of the same hole the air is...

Biggest source of leaks I had when getting tubeless sorted was air leaking out between the valve seat and the rim, then leaking past the valve & out of the spoke holes too.

Tightening the valve nut sorted it.

I found the best place to check for leaks was the bath. Makes it very easy - just the wheel/tyre though, you don't need to also get in!

The Mud X is only 'tubeless ready' as opposed to UST so can sometimes take a while to get sorted. The bath test is probably your best bet unless you have a mahoosive bowl/bucket.

Kitchen sink just about did the job, g/f's WFH so couldn't risk the bath.. well all the air pissing out the sidewall, even though there still a load of stan's fuild inside.
Any thoughts? Do I try leaving it on it's side (pumped up or not?)
I wanted to ride with this bloody thing tonight! Guess not.

whack it up to 40 psi and ride (take a pump just in case) it will sort itself out, as the rotation of the wheels and the compression of the tyre swirls the sealant all around.

hold the wheel 'flat' and just rock it gently back/forward and side to side - you need to get a good coating of sealant all over the sidewalls.

Do what wwaswas said first, then do what I said.

Just a quick thank you, leaving them on there side has fixed my issue, I'd had them stood on a wheel building stand and was spinning them regularly to swish the latex about, obviously not enough in this case.
There even still up this morning.

Agree with this, can take a while to get sidewalls sealed properly.

When putting them on the side use a bucket to place them on so theym nicely horizontal.
