Tire/wheel balance
Wondering how many folks have actually balanced their wheels? Like many I have a shimmy from my mains around 30-35 kts when rolling out.
I bought a wheel balancer and the wheels needed 1.75oz on one and about 2oz on the other. Virtually in the same spot too - near the red dot where you?re supposed to put the valve stem.
I took transition training in the factory -10 which also had a shimmy. The instructor told Me that the wheel needed to be balanced.
I?ve got the stock grove wheels and tires that Van?s sells as per of the kit.
I have to imagine that if it is indeed off by this much, this could be the source of the vibration.
Thoughts?

How are your tires after you did the balance? Shimmy gone?
I bought a Harbor Freight wheel balancer to use next time I swap out tires. I'm hoping it's worth the effort...can't hurt I suppose.

Karl - havent tried it yet. I bought the bubble balancer from Harbor Freight... the other one wont work... I tried. its for wheels with a less than 1.5? hub.
I?m hoping to get things put back together and fly in the next 2 days. I used proseal to attach the weights. 4 inboard and 4 outboard.

Balance
motorcycle shops have stick on balance weights in 1/4 oz increments. They can easily be cut into smaller pieces.

Hmmm...didn't think about the hub size. I'll probably just fabricate my own hub sleeve to make it fit.

Pull the schrader valve out and insert beads via a vynal tube pushed over the threaded portion of hte stem. Most bead kits come with a small bottle and tube for installation.

Won't the beads eat up the innertube? That pressure on somew points on the the innertube has to do something to it.
