After installing a new set of tires, how difficult is it to go back and add "Ride On" tire sealant where a new 90-degree valve stem (metal base) has been installed on the rear tire? Will this angled tire stem come off/out without much trouble--or not?

I gather the tire stem needs to come off/out to add the "Ride On" into the tire....correct?.....:confused:

It shouldn't need to come out. Last time I checked, liquids have no problem going through 90 degree bends ;-)

Remove the valve on the inside of the stem (bicycle shop will have valve stem removers), slide the tube over the stem, and squeeze in the appropriate amount of ride-on.

Why (and how) would you remove a 90 degree stem that is installed on a rim? I had no problem adding Ride-On to my bikes - both of them with 90 degree stems on the rear and a 90 degree stem on the front tire of the Nad. To the best of my knowledge, the only way to remove a stem is from the inside of the rim.

I've got a front tire that has a slow, slow leak in it (down 8-10 psi after about a week to 10 days) even tho' PO said he used Ride On. Had the shop replace the valve stem thinking maybe that was the problem, but it wasn't, so now I have a new tire that I'm gonna put on. BUT, let's say PO didn't use Ride On - just thought he had. The idea of the stuff is to fill pinhole leaks, right? Should I just replace the darned thing (now that I have the replacement) and be done with it? Or do you guys think I could seal it and it might be ok? I have the sealant, just haven't decided which way to go.

Chances are Cindy you probably have a rim leak. Ride-On Doesn't help rim leaks too much. Your best bet is to make sure they clean the rim good before mounting the tire.
I had a slow leak in my sidecar tire, kept an eye on it for weeks before finally taking the tire back to my tire guy. ure enough they hadn't cleaned the rim good so the tire never sealed.
You'd even have a leaky tire if it doesn't seat well on the rim. they took the tire off, cleaned up the rim good (good test is to wipe the rim with a cloth and if it doesn't snag on anything you have a smooth even surface)
It's also possible to still have a rim leak after replacing the valve stem because most places probably won't take the tire off the rim to replace the stem. You can break the bead move the tire out of the way (C-Clamp works good for this) , replace the valve stem, then reseat the bead

air up the tire to maximum, and spray or pour soapy water around the rim where it meets the bead, and where the valve stem pokes through the rim. also check the valve stem core itself. if you see a spot where the bubles keep forming and don't dissipate, you have a leak.If you find nothing, then put the wheel in a washtub full of water and look for bubbles. even the smallest pinhole will show up eventually, adding a few extra ( no more than 10) pounds of air will help locate any really tiny leaks. If you don't have a washtub, the soapy water trick will work on treads and sidewalls too if done in sections

I would also recommend checking the rim itself for cracks or porosities. These mag wheels have been known to do that occasionally. Both leak test methods will find these leaks if they are there.

If you do all the tests on the wheel and they come back negative. you may have pinhole in the tire itself that only leaks under road load, when the tire is flexing and warm. I which case a new tire would fix it.

Thanks - it's likely a rim leak, since the stem was replaced, and the leak occurs not under load (we had some bad weather after I had the stem replaced, the tire sat in the garage off the bike with 40 psi, and when I went to ride the other day, it was down to 20 psi). I'll run the checks you all suggest, since crud on the rim isn't going to change with a new tire. Thanks for the suggestions.

Thanks, Bulldog....but the above questioning had 2 basic purposes:

1) This is my first shot at changing motorcycle tires, and you can tell I've never done this b4, and;

2) I was going for the "stupid question of the month" award on the forum. :doh:


Thus far, it appears I was a runaway success...on #2, anyway....:BLAM:

There are no stupid questions here. Sometimes stupid answers but never stupid questions. Glad to help...
