Replacing valve stem on tubless tire?

Today I found that over the winter my rear valve stem has rotted in half. I am unfamiliar with the mounting of tubeless tires and parts...I payed a shop to install the tires last year.
How is a new stem installed? Do I need an OEM replacement? If not, which tubeless stems will work? The bike is an 86 vf500 original wheels.

Thanks

 

I believe they are generic..... any tire shop should be able to replace them.

 

There are tools you can get. Anywhere from $3 - 20
Here is what many tire shops use about $10 + shipping
Tubeless Snap-in Valve Insertion/Removal Tool - GEMPLER'S Instructions:http://www.gemplers.com/tech/valvestem.htm

Edit: Slime makes a tool like the ne listed above for $5ish available at Pepboys.

The $3 tools you can screw on to the valve stem and use a pair of pliers to pull it through. You can also just use pliers for t matter just try not to damage the stem.

 

Ok so this would involve breaking the seal between the tire and rim too. I thought maybe it would fit through from the outside. How do tubeless tires seal against the wheel rim? Would I need to re-seal it? Might be simpler for me to just bring it to a shop.

 

The tires and wheels are designed to be be mated. The bead on the tire is reenforced and mates with the wheel.
You need a bead breaker to break that seal and it takes a lot of force to do so.
You set te bead with air preassure. A preassure higher than opperating preassure from a compressor will set the bead.

In your case, I think it would be worth taking to a shop if you dont have the tools. Its like a $30 fix

 

I replaced my broken valve stem on my front and taking that old tire off was a bear- took like 3 or 4 hours and wore me out.
If you take it in to have it done have them put a metal stem in.

 

Great, thanks for the information guys. I will be taking it in to a shop. A metal stem sounds like a great idea...I will certainly request that :smile:

 

Post your location and maybe you'll get some cheap or even free help. I'm in Atlanta and have a tire changer in my garage and have done free work for numerous people because I enjoy working on bikes and helping others at the same time. It was a pretty good deal for them too since all they had to pay for was lunch.

Ditto, I'm in Sacramento, CA.

 

hee hee i've been changing my own tires for years and never knew there was a special tool for this. i've always just used a pair of pliers

 

I'm in northern Illinois..thanks for the offers though hahaha.

 

Before replacement, take into consideration the length and angle of the existing stem. If this is for the front wheel, an angled valve stem can be really hand when adding air to a tire (much easier than sneaking the air chuck around a set of brake rotors)...

 

The shop you had do the tire change should have put a new stem in automatically if the stem was rubber. Every shop I go to for new tires on a car, they put in a new stem. They are cheap. But seeing as you are going to have a new one put in at your cost, I really suggest getting a metal one of some sort. And get the angles kind They are some much better when it comes time to check you air pressure or add air to your tires.

You can find Ariete Bridgeport angled aluminum valve stems (11.3mm) on Ebay for $22 with free shipping. That is much cheaper then buying from Curveygirl. They are high quality stems and well worth the price. I've got them on both my bikes and have installed them for numerous friends without issue. The seller I usually buy from on Ebay is "Drahonmotorcycles"

I didn't know angled valve stems were available. I had a shop replace the stem in question on Friday though. Took like 10 minutes but he didn't have metal stems in stock and I didn't really want to wait for one, so I went with rubber again. The front wheel however, could definitely benefit from and angled stem. Soon I am going to be taking off the wheel and forks to have a seal replaced, at the same time I will look into getting one of those angled stems I think.

 

Good deal.
