Pugboy,
Thanks for the reply, I have just been remeasuring my electronics and I came to the conclusion that my speedo weighted 75g!!!
So to get to the same left/right (55/45) distribution as with saddle, I only have to add 90g at the right side which then leads to a final weight of 1690g.
The only thing that I am questioning now is the fore/aft weight distribution. Since the car was nose heavy anyway I am going to put most of the weight on the right back end side of the car.
Thanks
