[SOLVED] "is this tank slapper"?

[keratos]

Out of curosity, next time you change the front tyre ask the mechanic to check the wheel balance without the tyre and all balance weights off.

What tyres are you using? I found the sports tyres were worse than sports touring tyres as they sharpened the steering, but I prefer the sharper steering. It does not bother me, since there is no serious mechanical issue

just had it balanced, but with tyre on, kind of misses the point with it off I would have thought.
