[SOLVED] "is this tank slapper"?

[keratos]

Had it on my 2002 Fazer, hands off one day to stretch my arms, was doing 40 and the handlebars started to slowly wobble and got progressively worse, building up to a tank slapper, hands back on stopped it, was wondering all sorts, tyre pressures were spot on, I wondered about alignment of the frame, turned out to be the front tyre, odd wear due to having been run at too low a pressure prior to my buying the bike, had various tyres on the front and not had a problem since, I'd say make sure the head bearings are good, front wheel bearings too but most of all, tyre pressures and balance should be spot on, after that, hmmmmm

the tyre has been mentioned by several foccers. thanks. its defo something I will look at.
