I have to agree that spinning a flimsy plastic bottle with a drill motor isn’t really relevant. If the bead companies are in the wheel balance business, they should have proper equipment. Do they show an unbalanced motorcycle wheel on a computerized balance machine having the balance corrected by the installation of the beads? Do they then demonstrate the claimed dynamic balancing ability of beads by putting a weight on said wheel to unbalance it, and show the beads then re-correcting the imbalance? Are those videos available somewhere?No vehicle manufacture or tire manufacturer uses or condones their use under any circumstances. So i really doubt your NC came with them from the factory.
The youtube video bottle trick many report that as a parlor trick. Try the exact same set up with the bottle supported on an axle. So place a tire on a spin dynamic balancer and add beads......the balancer will never show balanced.
Beads products and liquid balance products are one of the most controversial forum discussion.
Motorcycle Consumer News did a bead test years back ........concluded they did no harm buy offered no benefit.
It is unusual that no one has a done a double blind test of these products over the years. Maybe like have 20-30 identical bikes, some with beads, some with weights, some with no balance of any kind, some with deliberate out of balance condiition. Then have 30-50 riders judge the performance.
As for auto manufacturers their spec of balance is 5 grams accuracy on 80 pound tire.
