Just fitted a yellow spring shock on Sat with the lnkages and went for a blast today. Found the ride very hard getting chucked out the seat at times and I am light weight.
Not sure about the dark art of suspension set up, does anyone have any advice or know of someone reliable in the central belt of Scotland that can set it up?
Cheers

Did you / Have you set your static sag?
On the assumption you have then you probably have too much rebound and you need to increase the amount of damping to prevent the shock extending too quickly and kicking back.
What settings did you start out with? I normally start with everything set in the middle and work from there, but this can vary from shock to shock especially if you have the std settings to hand.
Are you sure you have the right linkages? remember the Mille shock is from a sports bike, the set up will be firm and can kick you out of the seat occasionally
Basically we need more info, in order to try and assist

Thanks for the answer Falco9.
Have not changed anything on the shock it is as set from the factory and has before i got it covered 75miles now about 275miles came with the linkages from the bike it came off of.
I am not sure about static sag and the rest of the dark arts.
I found that when conering reasonably hard the back end seemed to be stepping out.

The following will help you set your static sag, once this is done you have the basis from which you can start to tune your suspension to your own preferences.
If you can't achieve these static settings you may be too light (not a problem I have) and may need to consider re-springing. But to be honest these bikes are normally set for a lighter rider, it's us fat gits that have the problems setting up
Anyway here's the basics, courtesy of Ohlins :-
Setting the spring preload
Measuring:
Preload on the spring/springs is very important,
because it affects the height of the motorcycle
and the fork angle. Consequently, handling characteristics
can be changed, even negatively.
Proceed as follows (it will be much easier if done
by two persons):
A Place the motorcycle on a stand.
B Lift up the rear end to a fully extended
position.
C Measure the distance, eg, from the
lower edge of the rear mud guard or
from a point marked by a piece of
tape, immediately above the rear wheel
axle, to the wheel axle. (R1)
D Make a similar measurement on the front
axle, e.g., from the bottom of the upper
fork crown to the front wheel axle.
The fork must also be fully extended. (F1)
E Allow the motorcycle (without rider) to
apply load on the springs and repeat
the measuring procedure. (R2, F2)
F Then take the same measurements
with the rider and equipment on the
motorcycle. It is important that the
rider has a correct riding posture,
so that the weight is balanced on the
front and rear wheel in the same way
as when riding. (R3, F3)
The measurements may not differ from the
following sizes:
Without rider:
Rear: 5-10 mm (R1-R2)
Front: 25-30 mm (F1-F2)
With rider:
Rear: 30-40 mm (R1-R3)
Front: 35-48 mm (F1-F3
