I bought in spring this year a ST3 with 50 000km and a uncleared service history. Well I was aware off that and planed for a major service later. So I drove about 7000km this year and let my local shop do an overhaul later in autumn. He got free hands to do everything he found on the bike, so that was belts,plugs,shims and all oils and so on. I got back a partly different bike with some noises gone and seems to be tighter and more powerfull than I expected. So the spring got more far away suddenly. Well merry Christmas everyone!
