A short while back i had a new front tyre fitted and on the way back from BSB it wobbled at a high speed, i found out that the wheel wasn`t balanced. So i had it balanced and not untill today i could test the wheel again and it happened again.
Can anyone help on why it should do this, i was told to lower the ride height which i can on my bike and change the bar ends to heavier ones and see what that does.
Dont really know much about this John but it could be because:
ITS A SCOOTER!!
There only made to do 50mph tops - or is that what you mean by ‘high speed’ 
In the words of Avril Lavigne " he was a SCOOTER boy, she said see ya later boy" 
Ultraseal?
My tyres are ultrasealed.
I know other users of Ultraseal have complained of similar problems at high speed. I also know that whilst the Ultraseal site says Ultraseal doesn’t affect wheel balance, Slime, which is almost the same stuff, says that a wheel with slime can’t be balanced and that slime in front wheels could lead to out of balance problems.
I suspect that the idea is that the Ultraseal/Slime covers the inside of the wheel wit ha minimal amount of pooling. If there is any excess pooling then this will tend to roll along at the bottom of the wheel. However, at a certain speed, dependant on the size of the wheel and the viscosity of the Ultraseal/Slime it will no longer be pooled at the bottom of the wheel and any pool will travel around the wheel.
I note that both websites say the amount of compund per tyre is critical and needs to be calculated based on the internal area of the tyre. Presumably this is to minimise pooling.
take the shoping trolly back to asda and get one from tesco.s .the weels dont wobble on them…
Start with the simple things…pressure. I’ve had tyres fitted and the fitter thought “he knew” what the pressure should be, but in actual fact was totally wrong…
I did the final test today, i lowered rhe rear and added hevier bar end weights and also downed the tyre pressure a touch. I also had someone look over the bike to see if they can see anything wrong with it and he said the bike is fine. I had a test ride and it still wobbled but not as server. So my conclution is that the tyre is great for normal and twist road riding but no good for high speed straight line riding.
You keep saying high speed - you need a proper bike again your starting to turn mad!!
What do you mean started, i`ve been mad for years.
Just been told that i`m getting a new tyre fitted under warrenty.
I had the crappy Michelin Pilot sport replaced for the Bridgestone and now no more wobble.
slopping any sort of liquid into tyres is a sure-fire way to affect their balance. I sell Ultraseal and Slime, but only to customers who really, really want it. Basically they have to convince me that they want to take a chance on high-speed chattering before I’ll take their money. Check out the Slime website. There’s a maximum speed recommendation for the stuff. Modern bike and scooter tyres are lighter and more sensitive than the square section crossplys that my dad used to pour a quarter pint of OKO sealant into back in 19oatcake. Wet tyre sealants were designed for use in armoured cars, not bikes.
If you want to avoid punctures, don’t take your bike anywhere. If you want to fix punctures in tubeless tyres at the roadside, buy a Rema Tip Top repair kit. 500,000 BMW riders can’t be wrong (probably).
Well after another nail, another chunk taken out of my hugger by said nail and another puncture, I swung into action again last night with the Rema Rep&Air kit. Job done, home in no time, no dramas.
I’ve been tempted to go the Ultraseal route instead but it seems there are significant drawbacks. I’m sticking with my repair kit. Never leave home without it (except when not on the bike!)
Aight! … repair kit … essential IMHO.
