Mine's the same. I find countersteering works best Craig, just a nudge and it drops in when you want it to.

In principle, yes, raising front forks up through the yokes will steepen the headstock angle.

I don't know specifics on the 1100 Breva and the rings on the forks but I would only mess with the fork mountings if you are comfortable with your mechanical skills - the consequence of yoke/trlple tree failure on the road could be fatal.

I believe the 1100 Breva has same (or similar) headstock angle as my 1200 Sport: 25°30'.  This is not a particularly laid back / slow head angle, the VFR800 has the same head angle for example.  I've never noticed any slowness in my 1200's steering but maybe I'm just insensitive.  As a comparison of the fork length/position, my 1200 Sport has a fork length of 49cm measured from the lower face of the bottom yoke down to the bottom of axle tube (the axle tube itself, not the hex nut).

Your tires will also impact the resistance or willingness to turn.
If they are getting towards the end of their life you will find a new set transforms the handling.
You can't buy happiness,
But can buy a bike and that's pretty close!

This is from the Norge manual, but clearly a B1100.

On my Norge you can just see three grooves, which is what I think that picture shows.

Hi
Thanks for replies.
Tyres are fairly new and as you said brian i expected an improvement when i replaced them but no.
I may try the 3 rings and see what happens.
Cheers craig

Raising the rear will sharpen the steering but may affect overall handling. Having watched my son in laws race bike being set by suspension specialists at Cadwell, they started at the rear with the `sag` settings with rider dressed in his kit sat on bike. When I asked which was the most important setting they said the initial `sag` was crucial followed by the back end before even touching the front end. They also mentioned that even a road bike could be improved by getting the factory settings `tweeked`, needless to say my son in law now does the suspension on my bikes, which in the case of my V50s is very basic. My RT1150 however is a complete mystery to the both of us (paralever suspension) and has been a case of `suck it and see`

Chris, set up the BMW rear suspension exactly how you would any other bike you have.

The "Paralever" is an extra lever to resist shaft-jacking, same as on the Guzzi CARC bikes & Kawasaki GTR1400. That extra lever doesn't impact on the suspension action.

I used that picture to show the number of rings showing. You can just see three, and that's the factory setting.

Thanks for that Tony it`s not the suspension itself it`s the way it seems to react differently to telescopics and the lack of feel at the front end, however these days I don`t take things to the edge anymore. If I need my tyres wearing right to the edge then I send my son in law out on the bikes

thanks for all replies.
i would imagine 3 rings would be the norm across these bikes.
i will give 3 rings a go.
the guy i bought the breva off seems to of had a tendency for tinkering
but not sure he was that clued up ( or researched that much )
but the most important things like servicing he was top notch on.
regards craig
