These work GREAT.  The bike runs smoother at speed than it did with the original tire balancing weights.  $17 for the kit with a 1oz & a 2oz tube of beads.  I put these beads into my existing tubes, although they warn against tubes that might contain oil from air compressors which will make the beads clog.

OK, I rode to work.  Maximum of 40 mph on a moderately rough road.  So far I notice no difference from before.  If the rain holds off, I need to run into town and can go on a 65 mph smooth road.  Certainly the things aren't at all noticeable.

Note that I mounted the tire correctly to the rim so the balance was pretty good before and I only really noticed a little something at 50 mph and above.  Didn't hurt anything, anyway!

OK bill, I have to hand it to you ... you are worse on this forum than I am ... however I'd give you a run for your money in saying in appropriate things on gstwin, mind you its quality and timing more than quantity over there ... but well ... I like it, the other sensitivities be darned.

I have a really out of balance wheel on the front of my 2000 savage, literally let the handlebar off at any speed and it starting bouncing, literally makes me think 1/2 the bike has loose parts on it.
So I am going to cram in 2 oz of this crap in there ...

If it works, I prolly will try 2 oz of play sand next.

Cool.

Interesting.  I see installation is pretty simple too.  Let air out, remove valve core, pour in beads, install core, reflate.  Sweet!  I can handle that!  For $12 I'll give anything a try.  

Most small air compressors are oil-free.  Larger or industrial quality air compressors that are oil lubricated will put some oil out with the air, especially as they get worn.  Good oil & water separators are available to clean the air, but the separators need to be maintained.

(The last large diesel engine I worked on was started by 450 psi air injected into the cylinders in the proper sequence to roll the engine over, then once rolling the air was cut off and fuel injected.  The air went through a starting air distributor then air start valves in each cylinder head.  The engine was 57,000 hp, reversible, straight-12 two stroke, heavy black 250°F fuel oil, direct connected to the ship's propeller shaft (no clutch or gear box).  We had three 100 hp compressors for this starting air as well as smaller 100 psi compressors for shop air.)
