BMW S1000RR shock conversion question

[kralik]

Set the rear preload 15 to 20mm, be careful not to wind the adjuster off the threads as it will damage them.
Set all damping adjusters to 4.
I weigh 85kg and my wife about 55kg which is 40kg more than your weight and have toured with that setting. 

After 20000km I changed the damping to 5 all round and never had to touched the preload in that time.

Hi,I just fitted s1000rr shock into my FZS and was looking for how to set it up properly.So, many thanks for your advices about setting up of damping.Just a question, the rear preload is for standard bmw spring, or is it with different spring?And the rear preload 15-20mm is from the top side right?
Anyway, I read some info, that the rear shocks use to have different length. For the earlier ones the lowering dog bone kit is needed and for the later ones it is not needed.How can I find out whether I need the lowering kit or whether I should stay with the standard dog bones, please?TIA
