Hey mountain bikers, don't throw away that clogged tubeless tire valve stem - unclog it! It's not hard, it's not time-consuming, here's the best way to accomplish the feat.
you saved me today. i found myself with a big ride tomorrow and a totally clogged valve core.....total disaster. But I found myself some turpentine, which was the closest substitute i could find to kerosene. thanks a lot for the tip!!!
Great solution, so far picking worked, along with moving valve core threaded thing, but eventually th seal wears out and the valve core leaks so I had to replace some anyway.
yoyoyo TY. Nice, but not sure how/where to buy kerosine now. I'll try everything other, first.

Thanks. Just converted to tubeless. Go for my first ride and tried to pump up the tyre before heading out. Nothing. Will fix this issue today as i know its the stem.
I think this may be my problem! When I try to put air in my front tire, the gauge on the pump just shoots right up to like 100 psi. I"m guessing no air/very little air is getting into the valve(tire) and its very hard to pump. The rear tire is fine. i'll have to head to the bike shop this weekend and get a tool and give this a try. thanks!
I took the valve core out & it was still blocked even with no core. So in my case its the valve casing blocked somewhere. Ill have to remove it completely.
I’m wondering if the product in the bottle has been sitting too long? Something is up. I just spent a frustrating night changing tubeless tires. Never had a problem before. Finally set over night. Now I have this problem you show. Changed the stem. Worked briefly. Now a NEW stem core is stuck. This clearly seems a formula issue? Thoughts?
Mine is so clogged that I cannot put air in the tires on my MB. I had been putting off fixing it until I couldn't keep the air pressure in the tire. I will try this today to see if It works. I couldn't figure out how to get the air out of the tire since the valve is clogged. I was gonna replace the sealant but I think it doesn't need it yet. Thanks for the info.
I’ve had this problem before but not for several years. I try to always make sure my valves sit closed at 6:00 for a minute to let any stans that may be in the valve drip out before I move them to 5:00 or 7:00 then open the valve stem to add air. I always make sure the valve is closed tight before spinning the wheel. I’m also careful not to use the bleed port on my floor pump so stans is not sucked into the valve or pump. Also have to be careful depressing the valve stem to bleed air so stans doesn’t get pushed out.
Great advice Ed, thanks. I actually followed your guidance and have had a better time of it. Still think something's going on with the formula, though. When I change tires I get all that sticky gummy residue on the inside lining. That wasn't the case before... What do you think?
@@BikeIntelligencer I think I agree with you about a change in formula. More recently I have had some sticky valves that can be a pain when adding air and they don’t seal tightly until you screw the nut tight. Sometimes I get a sticky buildup of stans in the tire and other times I don’t. I think this may be associated with using co2 to inflate the tire? I think I’m just going to look for some extra removable valve stems (the threaded in part) so I can just replace them easily as needed. Keep on making videos... you do a good job!
