I'm not aware of any mfg that uses dynabeads. As you probably know, there is quite a bit of controversy about whether they work or not.

I see three possibilities here: 1) You got lucky and your wheels balanced w/o extra weight; 2) the weights fell off at some point; or 3) Yamaha doesn't bother balancing at the factory and/or has a very tolerant balancing machine. Motorcycles are much more tolerant of imbalance vs. cars, so a "nice ride" doesn't necessarily mean well-balanced wheels. There are some who never bother balancing motorcycle wheels, especially on dirt bikes.

I've done hundreds of tire changes for folks... about 40% of the time the tire/wheel balances with no weights.

My front didn't have any but my rear did. When I switched tires both needed some... .no big deal if you aren't feeling any strange effects.

I'd say about one in ten wheels I balance I judge to be "close enough" without adding weight. But that's an issue here - what is "close enough"? Yamaha's standards may be much more tolerant than many DIY'ers.

I try to balance them so they don't move at all in any position... however, once in a while I find a tough one and it will 'creep' a little on the balancer. I would say you could easily be 1/4 oz off and never even feel it. I know some guys will change their tires on the road and not balance at all.

Mine has stick on weights on it. Either the factory or the dealer must have put them on.

I change my tyres so often that I ballance them myself. Its not that I keep wearing them out, I just keep changing from Tourances to TCKs and back to suit what I am doing in the immediate future.

I use thick solder wire and statically ballance them using just the axle without any other bits attached, i.e. no brake calipers or cush drive.



Its not pretty but it can be done in the bush.

If you place a lightest part of the tire, usually identified by colored markings at the heaviest part of the wheel, it may be in perfect balance.
But if you are note sure have it checked.

That worked for my Tourances, but not for my TCK80s as they do not have the paint markings..doh!

Some of the mfgs (notably Michelin) purport that their tires are so perfectly balanced that they don't need to tell the installer where the light spot is. Sounds to me like the tire mfg turning a cost-cutting move into a "feature", but that's what they pay the big bucks to the guys in the suits for.

Only way to know would be to balance the wheel without the tire first. Then install the tire and check. I have done this. Pilot Powers are pretty darn good...or I got pretty darn lucky...quite a few times.

A good trick is to find the heavy spot of the bare wheel before you mount the tire; then mount the tire using this as the spot to align the tire mark with rather than assuming it is the valve stem. This will minimize the amount of weight you need to add when you do the final balance. If you permanently mark this spot, you only need to do it once.
