Not got a C spanner supplied with 2005 SV1000S...
mr and mrs suzuki do not include one in the tool kit!!

Even suggests that only Suzuki dealer adjust rear spring preload
anyone any idea what size it is? (so i can order one) Or know any sites where can get my hands on one??
suzuki bike dealer wanted 10 quid which sounds a bit dear if u ask me just for a C spanner!!
