Tyre valve do hicky

[sinner]

Hi,I just checked the tyre pressures on my Valk.
The little box thing that supports the valve is missing.
Anyone know its official name so I can order a couple?

Thanks

Hi...

Find a place to order something like this:



To avoid this:



The plastic OEM valve stems in Valkyries really are just a flat tire (or worse)
waiting to happen...

Thanks Guys.

I will check with my local Honda dealer.

Just had a look on Oz Ebay. $A30-40. inc Postage.  (from US)
Must be gold covered in plastic.



So, the metal valve stems don't need a plastic support?

That's right. The support holds the stem in place at a 90 degree angle all the time. Some have stated that at highway speeds the OEM rubber mounted stem will try to straighten out with the centrifugal force causing it rip off or just crack and leak. The OEM stems should be replaced periodically especially if using chemical cleaners on the rims. Just my two cents. I am using these $2 stems now with no problem. The OEM units will work well too if you keep the plastic holder on there. By a few and keep one in the tool kit. That's what I did. Ride safe.

Bob (Brian?) is right.  The full metal stems don't require the support, but his science is a bit flawed.  Centrifugal force will cause the stem with the rubber middle to try to collapse.  In my opinion the greatest risk to ruin is not centrifugal force but pressing an air nozzle or tire gauge against the stem.  A torn rubber middle will crack and leak giving you a low to flat tire at the most unexpected and inconvenient time.  I don't think anyone has ever seen one rip itself completely off at speed.

Full metal stems don't have the problem.

Traveling w/o one regardless of construction of  right angle valve core may result in flat tire. Been there and done that and I had a metal version. Look on Ebay for them. I bought a lot of 10 OEM core retainer for $20.

You had a metal valve stem fail because you didn't have the keeper on it ?

Can you replace the valve stems at home without taking the tyre off the rim?

Yes, some have done it with the tire on the bike. I think it takes a couple big C-clamps.

Refer to Mikes picture earlier in this post and do a search on it. He has found that it can be done with a 8 inch C-clamp,,    I think he carries one in his bags.

This is us replacing one in a parking lot in Alabama...



After that (one of us had to run off an buy clamps, we had to really
scrounge for air to rebead the tire, no one had a board...) I made
sure I had the needed stuff in my saddlebags... here's me testing
an eight-inch clamp and a couple of boards at home...



Even if you could get the tire off the bead without the board (I couldn't)
you might not want to use the tire again... the board prevents
scary point-loads from the clamp(s)...



I haven't tested it yet, but this little hose screws into a spark plug hole
and can supposedly spew out enough air fast enough to rebead
a tire... it has a valve, it doesn't fill your tire with exhaust gas  ...

Yippers. Brand new with about 500 mi. on it after tires were changed. Mechanic didn't realize that a keeper was part of the tire change or neither did I. He was youngin' and I never experienced/seen this part before either. Heavier the object  in centrifical force the more pressure on that object to fail. The previous owner neglected to reinstall them when he had the Metzlers installed.

Thanks people!

I have learned a lot.


Just ordered Bridgeport Angled Aluminum Valve Stems.

I think those are super high quality... and I think you'll have to grind
off the nub that the plastic supporter attached to in order to
install them... that's why I went with the "regular" metal stems.

There's nothing really wrong with grinding off the nub... its not like
you'd want to go back to OEM valve stems...

There's "metal colored" OEM style valve stems, maybe they
came on those later Valkyries with the polished wheels...

I can't relate to one of these flying apart... ? ! ?

I don't know. My '01 standard with polished and clear coated wheels came with the OEM valves. There was part of them that were metal but not all the way thru. That's the only thing I can think he had. I don't see any way of the full metal ones moving at all.

I broke my standoff on my ACE Tourer by pushing the tire gauge onto it, not believing that the tire only had 15psi in it, I thought it was the gauge not sealing and getting a proper reading.

I now use a screw on tire gauge. No more problem. But I have also removed the stand off, and either used a billet stem, or one of the metal 90'. I just off set it, so it doesn't hit the mounting point on the rim, no need to cut it off.

I wonder why we don't just use a straight stem, like the front tire, just get a low profile. No centrifugal pressure forcing the stem to bend. Only difficult to get to on the Tourer/IS model rear wheels.
