VALVE STEMS AND DYNA BEADS
« on: February 08, 2014, 09:04:46 PM »

Can you guys help here a little!!??  I have been running Dyna Beads for the last few years. First in a 2002 Ultra. Then a 2005 SE Electra Glide. I installed the beads the first time in the Ultra through the valve stem. i had to use a vibrator and painstakingly take a lot of time to do both wheels. The '05 when i changed both front and rear tires at the same time, i put them in after one half the tire was on the rim. Obviously the simple and easiest way. When I had the wheels off, I noticed the metal valve stem had a smaller orifice, or so I think/thought, than the rubber valve stem on the '02 Ultra. Which was not a SE.

So now i have a 2009 SE Road Glide. I tried to put the beads in tonight on the front tire. I don't have a vibrating tool, but researched and found out you could put them in with low air pressure air and a blow nozzle, (YES i removed the valve core from the stem!!!!!) which i have (compressor and hose and air nozzle). Well, it did not go as the demonstration i found on youtube. The guy in the home made video was putting them in on a Gold WIng, with a 90 degree valve stem. They shot right in with a quick burst of air.

So my questions are: Are there differences in the valve stems, say from the rubber ones on my '02, to the metal ones on the SE bikes? and yet different from say a gold Wing? When i tried the "blow in" method, it created back pressure in my tube and and they basically "blew out" of the tube. and i was only putting in maybe 3/8" high in the tube from where the plastic tube screwed onto the valve stem. I tried different pressures. starting out low around 10 psi, and up to 30 psi. But that made no difference. Those beads are really really small and should be smaller than the orifice in the bottom of the valve stem.

After a shot of air, i was trying to"bleed off" any back pressure from the tube, beads, etc, and they would dance around inside the tube while the pressure was back flowing. Needless to say, i had quite a  few of them end up on the floor of my garage. so i packed it up, replaced the core back into the stem and aired the tire back up until i got some tips, tricks from some of you.

I have a palm sander, but could not reach the valve stem because of the brake rotor. i found out after the fact that from some researching i guess i could have used a wooden mallet handle and put that between he sander and valve stem. But i'm not sure if even "vibrating" them in would still work. i know lots have done it this way, but i wanted to post here before i try again tomorrow.

any help or tips would be greatly appreciated..........

thanks in advance.

No experience here but would try using a longer plastic tube and a funnel and then try to squeeze the empty tire to create a vacuum. Still might blow beads everywhere I guess and you still might need to use the side of an engraver as a vibrator. I'm tired so don't rely on this but it seems good at the moment.  ;D

I just had the same experience.  My first install of the beads was on my Gold Wing, and the air method worked great, on the HD all I managed to due is spew them all over the garage.  I did not have a vibrating pencil either, so I just used a screwdriver and continued to tap on the stem until I got all of the beads in.  After this I will install them when I have the tire broken down.  Just for information, I had the same problem with a street glide with the rubber stems.  The hole in the HD valve stems are just two small to easily install the beads.

Using an engraver tool helps a lot. Just put the engraving tip against the stem and the beads will vibrate right in.

thanks for the suggestions. i was able to get them in last weekend. i tried my wife's palm sander,and had no luck with that by trying an extension of solid rod. so i tried the air again and was able to figure out how to do it. basically, had to slightly pressurize the tire, CAREFULLY bleed some air out by letting it escape past the air nozzle, but not let them shoot out. they will start to "dance" or float in the tube as the back pressure pushes them towards the nozzle. i gave the nozzle some quick bursts of air and they would go into the tire. you still had to be careful releasing the pressure from the tire as they would try to come back out. so had to work the nozzle by forcing in a little air. got them all in. i also got a longer tube and that made it even easier. only took about 10 minutes to do the rear tire after i figured out the trick.

i am going to carry a couple ounces in a container in my tour pack so if i am ever out on the road an need a tire replacement, i can have the dealer put them in at the time the tire is put on the rim.

i cleaned off the old wheel weight adhesive residues and now am ready to ride!!!

thanks again for the suggestions and tips.
