BMW S1000RR shock conversion question

[unfazed]

Hello there from Italy  8)
after reading about this mod, I have replaced my original shock with a S1000RR '12 with 4000 km.
The shock works very good (everything works better than the original), the only proble is that with the shock fully preloaded I have a statit sag of 27 mm (against a reccomended 10-15) and a rider sag of 55 (against a reccomended 30-40). My weight is 90 kg
This make me thinking that the spring rigidity is correct, but the spring is too short, it'd be 10-15 mm longer.
What you think? Could I resolv with a 10-15 mm spacer under the spring?


ps sorry for my bad english...

Does your shock have the silver or bronze coloured shock fork. The silver one allow adjustement of the sag to 20mm the bronze one only allow adjustement of the sag to 27mm.

I did fit a 10 mm spacer to my silver forked one to allow more adjustment, but found that adjusting the sag to 15mm made it hop over bumps and set it back to 20mm. I weigh about 87Kg.
