Frik'n Baffled...

What's the update with the mystery? I am curious.

Thanks

Me too what's the answer?

Ive rode 20 miles since i switched tires out. Never had this issue with the original tire so "cracked rim", probably not. Im guessing the harley shop didnt clean the bead of the rim and something is around there causing a leak when the wheel goes around.

Either that or replace the whole valve stem, maybe when they broke the bead, the bead spoon on the tire changer hit the inside of the valve and screwed it up. They break the bead with a lot of force and when they let go the spoon snaps across the inside of wheel. I never break the bead on the tire near the valve stem.

I guess we will never know not the first time and for sure not the last time

We see this all the time on our race vehicles. The centrifugal force along with the weight of that shreader, will overcome the air pressure, especially if that shrader valve is faulty. In reading closely, the key tip off to it, was his mention that it doesn't leak a bit when left over night, but only when riding. It most likely is a faulty shrader. If it was me, I would change the valve with shrader.

As mentioned he checked the shrader in a "static state" and not in a "dynamic state".

We operate between 34 to 37 psi, of which is dependent on which dragster is in competition for that given event. The centrifugal force is greater on a 21 inch rim at the same given speed (rpm) of a 16 inch rim.

Uh, no. Centrifugal force is OUTWARD from the axle, not inward. Centrifugal force would force everything away from the center of the wheel, including the valve.

The valve could still be bad, but if the spring was weak 1) the air pressure would still push on it and 2) the force of the spin would further push it out.

Your not going to move the valve because that is locked into the rim, but the shredder in the valve is not. It will overcome a weak spring with enough inertia.

Actually since the valve is in the wheel with up/locked being towards the center of the rim, as the rim spins the outward motion would colapse the spring?? The spring is pushing the valve closed/up/towards the center. The valve is opened when it is forced in the direction of the tire- to the outside of the rim???

Havent been able to ride last few weeks but I did check it a couple days ago...36 psi. Only thing I did to it was replaced valve core and aired up to 40 psi. Plan on getting it out this weekend to give it a go

Fix-a-Flat will throw you out of balance and ruin your tire.
I've used a product called Green Slime for years.. It seals without collecting in clumps that will adversely effect the balance.
The advice about the valve stem is good stuff.
Good luck, let us know how it works out.

Rode about 70 miles yesterday and no issues. Either the bead was leaking and finally seated or it was the valve core I replaced. Who knows but it now holds air

Glad ya fingered it out at least ya know it wasn't the ECH

Prolly was the core, after selling tires for years and changing them, you get a collection of valve cores if you don't throw them away and its very easy for the guy that changed them to have put a much older or worn out valve core back into your stem.

Good to hear..

Good to hear for a minute there I thought you might have to put a Continental kit on the back of that dog.

Rode again today and no issues at at. Think'n I'm good to go but the A/C is stayn in the bag

 

[IRONHEAD]

You could put the old guts back in the valve stem and see what happens.

It's your shreader valve. Change it. Also put a cap that has a rubber seal in it. The centrifugal force is drawing it in because it's spring is weak.

I have to agree on this one...I had the same thing happen on a new tire change also. Took off, 5 miles down the road after getting up to 70 mph tire went flat quick, I almost lost it. Called my daughter, brought the trailer and took it home. Looked it over and put some air in it and a sealed chrome valve cap and it never went flat again.

I had changed the schrader valve when I changed the tire and forgot to put a cap on it. I will never run without a sealed cap again.

I also found out another problem when there is a flat on my bagger......the kick stand doesn't work!!! Had to stay on the bike till the trailer arrived.

Tru Dat, scared the shit outta me when all the air came out and the bike lifted off the kick stand, had to hold the bike up cause the side of the road had a lean to it until the trailer got there.
