V-Max Speed Wobble (ran it up to 115mph and...)

[Shuriken]

The first time I checked the steering on my 2007 Vmax it was far too loose with the forks bouncing off the stops when I jacked up the front end. After I had tightened them I found that it had got rid of the fast shaking at 85Mph but I'm still stuck with the frame wobble at around 90Mph even though I have fitted frame braces, though I can get to about 110Mph if I'm careful. If I hit a bump the whole thing goes into oscillation. The riding season is over now here in UK so I will try again in 6 months.

As much as I would like to lube or replace the head bearing and race on this 03, I am not going to even touch it right now with a 3 meter pole! The bike feels like an entirely different system when you have plenty of revs and stability to cross over the ton and don't have to worry about the wobble. 0-100 is nothing for this v4 engine, so it sucks having the instability rob 25% of the bike's capability.

I don't need to ride around that fast but the more stable it is at 100, the better it feels crossing lanes and all around at 75.
