Easiest way is to hold an engraver tool against the valve stem. The vibration helps them flow through.

 

From the FAQ on here http://www.innovativebalancing.com/news.htm

Can I put the tire on a balancer to see if it's working?

A: No. Dyna Beads operates on physics principles, and requires the tire assembly to be in motion against a road surface to detect the exact counterbalance position. An electronic balancer has a solid, fixed mount, and does not allow the tire to react to imbalance.

I have been using them for years and love them, Not a wheel weight 1 around my house . Only had trouble 1 time and the tire was bad. Bent wheels can cause problems as well.

 

I used the beads on my last bike. Not a problem. matter of fact, it worked better then with lead weights.

 

Save yourself some money and go to Walmart and buy some airsoft pellets. They are plastic and won't hurt the tire. I bought the 12 gram pellets it takes 250 to make 1oz. been using them and they work great. 5000 airsoft pellets cost around $10.00. Just put them in the tire before you set the bead and all is good.

 

I just thumped the valve stem with a screwdriver as I poured mine in...worked just fine.

 

[QUOTE=BIGVTWIN;9538411]I can't get them thru the valve stem. And yes I removed the core from the valve stem.
Any ideas?[/QUOTE

Sometimes you need to run a 1/8 drill thru the stem to clear it first. I had to with my tube tires

 

I have used dyna beads in many applications and they are great. Using another product in a recent tire change on the UC called Ride On. It offers the same dynamic balancing as the beads, but additionally it will seal certain punctures. It is a water soluble liquid that will not corrode metal. So far it is working great with the balancing, hope I don't have to test the puncture feature. Be safe out there! Still have beads in my other bikes.

 

I use a pipe cleaner and run it through the stem several times. I have never had to do anything other than just tap the stem with my finger to get them in after using the pipe cleaner.

 

Unable to get beads in. Finally thought to get the tire off the floor and beads flowed in as advertised. I like 'em. Several friends got 'em & all like the beads.

 

Here's the other question - how do you get the weights without marring the wheels?
