Head shake/tank slap?

[CWCobra]

By the way...when I dismounted the Shinko, I did notice a surprising amount of "tire junk" mixed in with the Dyna Beads inside the tire casing: small black balls mixed in with the white beads. I cannot speculate whether the beads caused the tire to erode from the inside or not, nor if so, whether it is damaging to the tire.

At any rate, I'm using old-fashioned lead on my Metz when it gets here.

Not trying to persuade any one to use dyna beads because I really don't care what someone else uses to balance their tires, but I have used dyna beads for about 16,000 miles on my Rocket. I've been up to about 125 mph a few times and I've never had a hint of vibration or wobble. I changed the front Avon at 12,500 miles and I put the recovered beads in the new Dunlop Elite 3. I run Darkside on the rear it might be half worn out at 16,000.

There was a some tire trash from to old tire mixed in with the beads.

No offense but the theory about the beads wearing out the inside of your tire is IMHO horse sh!t. With the price of the Shinko being so low maybe they cut some corners in the QC department. Some times you get what you pay for.

BTW note to HellFire, I was really surprised by your negative opinion of Dyna Beads having never tried them. You were surprisingly open minded about Darkside tires before you tried it. I bet there are a lot more people using Dyna Beads than there are running car tires on motorcycles.

Here's a pic of a small metal cup containing DBs recovered from my Shinko. I suspect the black specs to be loose dregs from inside the tire, and to be of no consequence. My thought now is that the Shinko is defective, and DBs were unable to overcome the defect.

Sh%T!!! I'm going for it on the next tire change front tire and rear.... Dyna Beads it is. I'm so tired of the sticky glue that will not come off on lead weights. I still have a place from the last time the lead weights was removed. If they don't work then Dyna Bead company will here from me. (like they would actually care... they've already got my money)

Technically there shouldn't be any Dyna Beads or weights on the CT anyways. The tire shop that does my tires said that CTs always need no weights cause they just balance out that well. The fellow that told me this is a good friend of mine .... no BS here... I asked him I don't see any weights was the tire balanced and he said yes it was. Sure enough it felt perfect.

Well, head shake is cured!

Here's how it all ended up: vendor gave me a refund for the Shinko. So, I purchased a Metzeler from Bike Bandit, and mounted it instead. I was so eager to get the Metzeler mounted, I forgot to take my wheel balancer and lead weights to my shop, so I decided to re-use the old Dyna beads instead. But when I poured in the beads, even tho I thought my tire was sealed on the rim, I was wrong, so all the beads spilled out on my shop floor. So I said, what the heck. I lined up the red dot on the Metzeler with my valve stem, aired it up to 40 psi. and put it back on the bike.

Result: No wobble. Rides straight and true all the way to 100. I don't yet have the nerve or road space to go higher. But I am convinced: no balancing medium can compensate for a defective tire. And a quality tire doesn't necessarily need any balancing media at all. YMMV

so once again all the darkside-haters are quick to blame the car tire and it obviously was not a factor.

glad you got it sorted.
