My bike has recently (and suddenly) developed a high frequency vibration which cuts in at about 75mph. It's still there at about 100mph. The only thing I can think is that it might be something to do with the Gloop stuff I put in the tyres (you know, the stuff that instantly heals a puncture hole). I'd have thought centrifugal force would have spread it evenly inside the tyres and balance things up, but maybe it can cause your wheels to get unbalanced...what do you guys think? If that is the case, would wheel balancing cure the problem?

Yes, I agree its the junk you pumped into the tires, I had a bad vibration problem in my bike , it was the rear tire, I had a new tire installed and the vibration is gone. I didn't have fix a flat junk in my tire, it was just a cheap, generic low quality tire IRC brand

What David is talking about is not fix-a-flat , but rather a product called slime which should not be causing the vibration .
And Slime is one of those products that actually works as advertised .

not sure i would want to trust a tire that had been patched to be safe at 100mph, but that's just me. Take the tire down to a shop and have them look at it, maybe something else happened when it got punctured like the rim being warped ever so slightly.

i doubt its the goop stuff. that said, i'd replace the tire, because the tire was punctured and I dont like to take chances with damaged tires when im only driving on two wheels.

The tyre was never punctured - this goop/slime stuff as far as I understand it is meant to prevent catastrophic blow-outs and stops the tyre deflating very quickly. It just lies around inside the tyre waiting for a puncture when it seals the hole. I agree with you about not taking any chances at all when you have so little rubber touching the road.

I have heard of cases where too much goop for the tyre can though it out of balance if the instructions were not followed properly.
