Head Shake and Tire Changes

Had some head shake when letting go of the bars at around 40mph. Did it every time. Replaced the stock 5600 mile tire with an oversize Pirelli MT66, and all is good now. No more shake.

I remembered people asking about head shake, so I thought I'd throw this out there.

I used a bench vise to break the bead, and went to the local tire store to buy some 'dynabeads'. They have them for big trucks, just a different name brand. The bag I bought was 12oz, I believe, and cost me $10. I just measured out 1.5oz for the front tire, and saved the rest for future installs.

Good Luck!

Don't know much about the "Dynabeads" but know it's hard to get all the shake out of the front tire... My present front has 13+K and I have a new one at the shop and dread to make the change as it is the smoothest running tire I have had... I do have a balance stand and some small weights, and I will double check the new tire when they mount it on the rim before I install it, then a bit later on when I have ran it a bit...
And like an auto tire about 40-45 mph is when she starts to shake her ugly head...
Have a good one...Old Dog...

I been pretty happy with using Ride-On instead. Does the same basic thing dynabeads do , but also seals punctures.

You should however have the wheel balanced with static weights, and if needed, use dynabeads. It sounds to me like you added 1.5 oz of them with out any knowledge of how out of balance the tire was to start with?

Is that the reccomended amount to use in that size tire?

There are other reasons you can have "head shake" at certain speeds other than tires. I don't think I ever noticed any shake on my bike, but then, I never really road without using my hands..................

I used this to determine the amount needed. It just lists the size cutoffs with what they sell, at either 1oz or 2oz.

http://www.innovativebalancing.com/c...otorcycleChart

The oversized front tire is kind of in the middle, and with these, a little extra doesn't hurt anything.

No out-of-balance noticed while riding so far, and no head shake when letting go of the bars.

The beads I bought come with a spring loaded valve core. It keeps the beads/dust out of the valve core seal. It requires a 1-1/4" length valve stem, which I installed. (stock was a bit shorter) If one of these is not used, the literature recommends adding a small blast of air before checking tire pressure.

The beads I bought for a semi truck look identical to the Dynabeads, and were small enough that they could have been fed down the valve stem. The tire shop swears by them, especially large tires, problematic tires, or ones that would require a lot of weight to balance. The cost was $10/bag for any size... so I bought the biggest one, as I have a sensitive scale for measuring the amount I need. It was 12 ounces.

The brand is Tech Plus.

So do you get the nice pinging sound from these when you come to a stop?

Not to hijack, but as a way of explaining my question...

I was off roading in VA a couple of years ago with my Jeep and I must have loosened a wheel weight on a rock. I was heading down the highway when I heard something hit my front fender. At the same time the steering got a bit shaky.

I found the next town to see about getting the wheel rebalanced as I didn't trust the spare for a 500 mile drive. The only place was Wally World, and they could not handle 35" tires. So I went inside to see if I could find some BB's. I ended up finding some. So I am in the parking lot with my tire off, spare under the hub, breaking the bead with the Hi Lift, and then pouring BB's into the tire.

Worked like a charm. But sound weird when you come to a stop and all the BB's that were at the outside of the tire lose momentum and start falling on to the wheel. Ping, ping, ping... Best is when you stop quickly and you hear them rolling around before falling.

I knew some people with 42" tires that used golf balls instead of BB's.

End hijack

Alway do what you said you would do drunk. That will teach you to keep your mouth shut.

Don't think so. I believe the Dyna Beads would get stuck in the Ride On. If you have Ride On, you don't need the beads.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
