BMW R1100RS

A lot happened since my last post. The guzzi is in serious need of a gearbox overhaull, the electronic ignition is on hold due to the need of an suitable motor with variabel speed, I changed jobs and in serious need of free time.
In the mean time purchased a BMW R1100RS with only 37000km on the clock. Nice! Not the kind of bike i like for looks, but the kind of bike that will take wherever I want , whenever I want!
And it does!!
BUT...
I bought it cheap and in excellent condition.A top second hand buy, but from a design point of view suprisingly, this Beemer is crap!
- Severe pulling to the right, and not because it has a bent frame, nope, because it's darn common for an oilhead...
- steering capabilities of a german tank.
- handlebars mounted on rubbers so, at a certain level of vibration, you loose all input from the front, wich by the way sometimes scares the living hell out of me...

Checked the internet and I found out this common for this bike... The pull to the right syndrome, is a lot spoken of.
Read this article first:

Four schools and my opinion:

1)The weight of the bike is biased to the right.
Yep! Measured it, and can proof it.
2)Its caused by torque from the boxer motor
Nope, cut of the engine while driving and it still PTRs. There is some torque while standing still and even some torque but completely neglectable while driving.
3) The suspension is not properly set up for the rider
Suspension on the BMW is weak but if you fiddle with it you will find a suitable setting that add's up to its drive abilities.
4) The front and rear wheels are out of alignment with the bike�s CG (Center of Gravity).
SO TRUE!

Here's what i did.
