I think what you're experiencing is the normal gyroscopic precession which is normal of course , but is felt more pronounced in the GS due to the steering set up (para lever ?)
Loose front end?

Oh , and have you checked the track rod ends for wear ?
Don't be daft, it doesn't have any. It might be the king pins though.

Mine has below par shocks which are not leaking but for sure less than they should be. But the bike can still out-handle most other riders on the road. Tyres are wearing normally and there are virtually no chicken strips.
Put bike on centre stand and check everything at both ends for free movement and excessive play. The steering head bearing (in top yoke) can get stiff if not knotchy which can affect the handling - should be completely free moving.

What tyre are on the bike and how old? My wifes 1200R has just had very same problem. We were on the motorway she said the bike was startin to vibrating badly. I rode alongside and had a look and front wheel was jumping about like a mad thing. Pulled on to hard shoulder, on mainstand and spin tyre. No lumps bumps or out of line or nails etc. Pressure a little low pump up and on our way. As soon as she hits 60+ starts to vibrate again. Lots of checking suspension, discs and so on. Short of it was a new tyre fixed it. Suspect a cord had let go and was distorting the tyre at speed. Nothing showed up when it was removed but tube had a small hole and was punctured.
Tyre was due for replacement but not illegal Pilot Road 4

PR4 trail's, front is good but back squared off very slightly. Bike seems fine all over. Gave it a 'top to bottom, front to rear' check over the weekend but nothing seems amiss.
Think I'll give it to Bahnstormers to take it out and asses it.
again, thanks for the replies.

Tyres with tread lumps are often less bad at speed - gaps between lumps rush by too fast for the bike to drop so vibes reduce. Very not good of course.
Out of balance tyres get worse at speed.

Well, had new tyres fitted yesterday, Avon Trailriders. Apart from the initial ride out of the fitters in very wet conditions feeling like riding on ice I managed to take the bike for a ride yesterday afternoon when it had dried out to bed the tyres in. Rode the bike in to work this morning and gave it some stick, the problems I had before have now gone 
The tyre fitter did checked the balance of the front wheel and told me it wasn't good at all. Happy ending

There we go. Tyre out of balance shows up at speed.
Yes, and now I'm a happy man! Thanks Bendy.

The Avons will only get better over the coming days, with a few hundred miles on them.
I also reckon I'm gonna get 2 rears to 1 front.Glad I took your advice on the tyres, nice one.
Haven't been able to do this so far with Michelin, Pirelli or Continental.

My TKC-70s are virtually worn out at the back and badly scalloped at the front so I may try the Avons next time.
I don't think you'll regret it.
It's the scalloping at the front on the TKC70 that made me lose patience with them. Probably a couple of thousand kms left on them when I took them off the bike.

TBH, I've liked the TKC70. Of course, not as good on fast roads but absolutely great on loose gravel over tarmac. We have lot's of that on the narrow Devon lanes. But the front being pretty much B****xed at the same time as the rear makes them expensive.
