does anyone here have experience running dyna beads for balancing? I have a front wheel on my s3t that may be out of balance, going to have it checked, it currently has a lot of weight on the rim to balance it. the shop I talked to say they work great....not a harley shop by the way...but, prefer to hear from someone with experience.... | ||

noooooooooooo please say it ain't so joe seriously- totally hashed out with no agreement way too many times do a quick search for dyna beads, prepare to be inundated. | ||

Once again: if you are interested, give it a try and report back. Too much hearsay on the web - it would be good to get feedback from someone directly here on Badweb. I guess the worst that could happen is that you end up with a couple of spoon-fuls of little white beads spilling out when you change your tire the next time. | ||

I've been doing it for years on all types of things. For starters... dont worry about buying expensive "DynaBeads" if you are going to continue to do it. Just use airsoft pellets. They are far more cost effective, and locally available at walmart. As far as the actual physics of it. I'm sure you can do a real read up on it anywhere you want... But I'll give you the real short end of it... no bullshit added. For a car... I highly recommend doing it. You never have to balance a tire again, and they are smooth as hell. You'll hear them rattle as you come to a stop a bit, if you have aluminum rims. Not so much on steel rims. The positive, is its consistantly dynamic balancing. Whereas permanent balancing immediately starts becoming incorrect the second you start driving. HOWEVER. On a motorcycle there is a fine line between using them or not. If you are using your S3 like an S3 should be used... which I assume you are. A touring bike. Then go to town. Use them. Any type of driving around highway and city miles, they will be fine. Most people get arrogant/cocky on just HOW good of a rider they are... but realistically 95% of riders are not riding aggressivly enough to even use the nice expensive tires that are made. Now I would not recommend these in something like an R1, where your going to be doing some real Track miles. But for the rest of us... they are fine. Lets face it. They balance, and really just dont present any sort of danger. Enjoy. | ||

I put the balancing goo in my MZ, since it has tube tires, and I was afraid it might hurt the tube-even though they say otherwise. The goo, I can't remember the name, looks like the green slime hole filler. Why it balances and the cheaper slime does not is a mystery, but it did work. It also tends to stay in place at a rest better than the beads, which really doesn't make any difference. The bikes tires don't vibrate much at rest. Using airsoft bb's is a novel idea. They look larger than the dyna beads, but I have tons of them. How do you decide how much to put into a tire? | ||

I have a local shop, uses them a lot in the high dollar chrome rims that the posers run on their Hyabusas turned straight line no corners bikes.....its kind of a local run what you brung type shop, not sure I would trust them with a motor, but quick easy things like tires and balancing, maybe a carb cleaning if I simply dont have the time....I'm correcting a problem that is somewhat of a what caused what. the front tire has some very light cupping, cant see it but if you run your hand on the tire you feel it beginning to take shape. there is a lot of weight on the rim, not sure if maybe the tire needed to be rotated 180 degrees and mounted and balanced again. one of the pinch bolts was missing and the other three were finger loose...so, did the axle have room to wobble a bit under heavy braking and corning which caused the tire to cup which sets up the feedback, or did the tire cup which caused a vibration which transfered to the axle to the pinch bolts and walked them out....the starting point though is that there is a lot of weight on the rim.....anyway, I may have had three issues and not sure I am at a point to change all three variable and then say for certain did the dyna beads work. Im thinking new tire, have correctly torqued the pinch bolts and axle retaining bolt, and might try the beads....and see where I end up...three different issues though, all related. I am not a track rider, I dont have a bike I would like to see sliding down the track without me, or forbid, sliding down the track with me! so all of my riding is done on the public roads with about an inch, maybe slightly less on the chicken strips, just cant afford to push that hard at my age (just slightly over 40 and heavily vested in the military) and with that much to loose. so for me, they may work?...my thoughts, (not an engineer) are that as a tire is worn, it changes shape and therefore within the first few hundred miles your static (stuck on weights) my no longer be true balanced....dynamic balancing that can shift as needed as the tire wears would find true center balance...how fast does the tire have to spin to pull it into balance though? why would a lean angle change the effectiveness though? I use my flying background for this...as the bank angle increases, the vector of lift changes to match as does the opposite vector, so a spinning tire in the vertical plane would have a downward gravity pull (centrifugal force outward to the vertical plane), as the bank angle changes, the centrifugal force would change in direct proportion...? like the tie lines of thrust lift drag etc.... remember though, not an engineer...just a pilot line of thinking... | ||

Anyone who tells you to put the BB's in through the valve stem first off... is Nuts. Just crack the bead of the tire and drop them in that way. Secondly, Its not the lean angle that effects the BB's. Its just harsh changes in vector. IE. Slamming back and forth. Fast susspension compression and rebounding. Just things that would make them Ineffective. As for the point of being effective? Almost immediately. They start finding their relative outside slightly over 3-5 mph. Just because you are not moving fast you have to realize the tangent of the wheel is moving fast... As for how much, You measure by ounces. I used to have a chart, that went by Tire size and weight. For a 38" rock crawling tire that were on my Jeep I used to use 9oz of BB's for example. | ||

Waste your money on what you want, but if you want to balance a wheel, you can get a static balancer for under $100 pretty easily (long straight shaft with 2 machined cones and 4 bearings and some kind of stand). I got my setup for under $50, but i had to weld up my own stand for it (that clamps in my vise). If you don't want to balance wheels, that's not particularly crazy either. Modern tolerances in manufacturing are getting pretty tight, I doubt most wheels need much balance anyway, or that you would notice much when they are out of balance. If you want to put airsoft BB's in your wheel, or nicely re-branded ceramic tumbling media from people putting out smoke and mirrors youtube videos, that's your business. Heck, smear chicken blood on your windscreen and say "banana" backwards 8 times quickly to balance your wheels if it makes you feel better. I don't think anyone can claim dynabeads actually work though. They can just claim they think they work (which is their business). Every objective and rigorous test done on dynabeads ends with excuses on why they work, just not under that test. I started cautiously skeptical, the longer and harder I looked the clearer it seemed to be that it's pure snake oil. Even if it worked, it would be stupid to throw 4 to 12 oz of weight on there to balance a sportbike tire (unsprung and rotational the worst possible weight to add). Just add the 1/4 to 3/4 ounce your static balancer tells you that you need right where you need it. Or have a shop balance the wheel without the tire on it, add that weight and leave it there, and assume that name brand tires will be fairly well balanced from the factory (a really safe assumption). | ||

First off... They do work. I got 52,000 miles out of a set of 36 inch mud terrains, without a scrap of cupping or uneven ware. That is unheard of. Secondly, anyone who is putting 12 oz, much less 4 oz in a motorcycle tire is doing it wrong. you might need about 1-2oz. | ||

Reepicheep said it well. Almost any modern tire is close enough under 135 mph. Balance the wheel and leave it. | ||

When I put the new tires on my MZ, I static balanced them using the wheel bearings, not as good as a real balance machine mentioned earlier- with easier turning bearings. They both showed balanced, i.e. I could spin the wheel and it stopped in a different place each time. However when I rode it the first time, I could tell it was vibrating. My 21" front has a tube of course, so I wanted to stay clear of the beads, and when researching them found the ride-on goo. To me it looks just like the green slime that has been a tire and tube sealer for years, so why it wouldn't also work I have no idea. This stuff is white instead of green, and whether that is due to a dye or the actual compound, again I have no idea. It did change things for the better, and the wheels don't vibrate now. The added benefit of it sealing a future leak was just icing on the cake. I wouldn't care if a 1,000 studies showed it not working for them, it worked for me. Your results may vary, but I wouldn't think so, unless your vibration is not caused by an out of balance tire. With the Buell, I have never felt the need to do anything, as it has never vibrated. Not broke,so I ain't going to fix it. | ||

tried the chicken blood and banana approach since it seemed cheaper, I was having chicken for dinner anyway...now Ive got two problems...front wheel still vibrates slightly and my windscreen is trashed... wheel comes off this week and balanced one way or another...Im leaning towards what I know. balance the wheel with the "old style" of weights, and ride, then if Im feeling like wasting some quality wrenching or riding time and some dollars to boot I may test the other method for comparison.... after all of this, still completely undecided, except for the obvious..no more chicken blood, damn thats messy!  | ||

new front tire, balanced the "old fashioned?" way with weights on the rim....new brake pads...no problems.....its a new bike for me so wanted a known process to see where the vibration was coming from...now that problem is solved, I'll sort out if I take a step and run a test with a different balancing system... | ||
| Reepicheep |
Check! No more chicken blood! We have now proven it ineffective.  | ||

When I need to balance, first I sacrifice a hecatomb, then read some of the livers for divination. If the gods are pleased with the offering, the tire will be balanced. Woe to he who offends Vulcan, god of rubber! | ||
| Jolly |
so there are the carburator gods for proper jetting, th voodoo black magic gods for fuel injection, the god of vulcan for balancing....when my s1 really sings (growls??) I am in definite step with the primitive gods.... Its my favorite bike in the garage for all the right (wrong??) reasons.... by the way that s3 (bought from a guy here on the forum, grey and orange frame) is now my favorite bike to ride to work...haul my junk in the saddle bags and ENJOY! save the streetglide for road trips with the girlfriend... so s3 monday through friday, s1 on saturday...x1 on sunday...motoguzzi on sunday afternoon....thruxton for ice cream sunday evening...  | ||

Get the girl her own ride and get get rid of the Street glide . | ||

she's got a 2004 Triumph Bonneville that I bought her last summer...yep she is "vested" in the bike thing!...still likes to ride with me though, and shes not comfortable yet on long rides...so the streetglide works for us.... I never could understand the concept of "one bike to do it all" so.....Ive ended up with quite the collection....3 tubers, 2 brit bikes, 2 harleys, 1 goose, and 1 Big Dog chopper....and one VERY understanding girlfriend!!!!!! been collecting for a while now and used some cash from a very long deployment to cover some of the collection. Ive recently been wondering since things are running in at least twos, does the goose need an italian friend?? thats a bad rabbit hole to be peering down...!!!! girlfriend says wife status and kids are next though.... | ||

I wonder how many of the magic bead proponents are also Obama hopey-changey advocates too? | ||

Blake, sometimes you are such an ass. I really feel sorry for you. Does this part of Badweb look like the quick board to you? Are you lost? Or do you just enjoy going around trying to stir up shit? Shane | ||

I have not balanced my tires the last two sets I have put on, I could honestly not tell one bit a difference! If I were racing I might balance them, but I'm convinced modern tires are pretty good from the factory! | ||
| Fahren |
I think I would get a dynamic balancing done every so often also, though, as it may tell you things about wheel bearings a visual inspection and static balancing won't. |
