TYRE STEM VALVE SIZE ?? Anyone Replaced ?

[MaxyMax]

Hey team, hope you all well.

Wanted to quickly ask if any of you knew what size replacement i would be needing for my GS500 2014.  The Valve Stem thing has split and wont hold any air anymore.

Also wondering if anyone has had experience with those quick-screw valves . where you don't need to remove tyre to replace .
Im wondering how you get the old valve out if you're using that method, is it possible to pull the old out? all the way through that little hole.

As always, much appreciated for anyone taking the time

I would do it properly and go for something like this.

Sorry, dont have any note of the size but I think they are a standard size.

The tyre has to come off the rim to remove and replace the valve stem.......take it to a shop.

11.3mm metal stems will work, otherwise any typical rubber stem you can get from an automotive store should work.

You can pull the old stem out with some force and swear words, but if the valve is already damaged what is most likely to happen is it'll shear off and leave it's butt inside the tire to roll about until you replace the tire.
The harder part would be getting the new stem IN from the outside.  I've seen a tool the military used to use on Jeeps which forced a valve in with compressed air or something, but I can't imagine it's that good for the valve stem.  Probably just an emergency procedure.
Generally speaking you need to break at least one bead and go in from the back.  You can get a cable tool to help with this, and use soapy water to lubricate, if you want to try it yourself.


Tires aren't insignificant things, though, especially not on motorcycles.  I'm with Sledge, take it to a shop and have them do it so the tire doesn't get damaged and it can be re-balanced if necessary.
You can save money by pulling the wheel yourself instead of riding/trailering the whole bike down.  I'd anticipate a valve replacement off-bike will run you $30-50.

well my nearest mechanic is 25 km from my place, riding that far on a flat may not be the best idea, so i have no choice but fix it.

also Have you seen the clamp method ? really doesnt look to difficult . all your ding is squeezing the wheel back enough that it exposes the rim hole for the stem.

means you dont need to take the wheel off, your just pushing it to the side really.


and then the quick screw valves i was mentioning, apparently you dont even need to do that

The downside to something like those is you should probably regularly check they're tight.
With a typical valve stem it's flanged on the back, so even if the nut gets loose over time you won't lose the valve stem.

Not saying it's likely, but if the nut gets loose on one of those and your wheel spits it out you're left stranded with no valve stem as opposed to just needing to snug it up and reinflate the tire.

Something worth considering.

You still need to get the old one out of the rim and if you want trust what could be your life to one of those things.............go right ahead
