OK -- After taking advice on here (thank you all), my ZX10 R (05) rear shock arrived from fleabay last week, and looks in great nick .. K-tech springs arrived today (great service !) so I guess this weekend the bike is going back into the 'workshop' ( my kitchen ..) for some upgrades ... !!
Adjustable suspension is something new to me -- any recomendations for 'base' settings for the shock, preload / compression / rebound ? I'm thinking about 15 mm of thread on the shock body, and mid-setting on the compression and rebound screws ... ? All suggestions welcome

Oh -- and will the stock SV bottom shock
bolt fit , or do I need to source a longer Kawa bolt ?
Thanks in advance !
