Starting a new thread so as not to hijack another.
Even if the tire and wheel look fine when you're spinning it around, the wheel balance can be way off.
When I got my Znen 150 it was hopping and wiggling all over the place. How am I supposed to be able to notice the important noises and vibrations? Fix the wheel balance.
There are commercially made wheel balancers available. The free rolling bearings allow you to make very fine adjustments. They're not necessarily cheap though.
in it's simplest form all you really need is a stick and a flat surface to let it roll on. Maybe not as super accurate but you can at least get close.
For a scooter front wheel you can just use the front axle as the stick. I clamped mine in a bench vise. Or you could roll it between two boards or something.
For the rear I found a piece of electrical conduit that I was able to shove through the rear splines. Not perfect, but reasonably close.
To balance the wheel you can spin it and wait. Or turn the wheel
degrees at a time and then let go and see which side goes up, and which goes down. Keep adding weight to the light side until it doesn't want to move by itself anymore.
I bought a couple strips of stick-on weights at the local tire shop. i had to add 9 squares to one side of the rear wheel before it quit moving. That's a lot for a small wheel. The end result is well worth the effort.
If your wheels are reasonably close already and you're game for some voodoo magic, you might consider trying Dynabeads

I've got them them in the wheels of my big bike. I still don't understand exactly how they work, but they do. At least until you get up above 80mph which shouldn't be an issue for most of the smaller displacement scooty crowd.
