DaveOnce again many thanks. All advice is useful I feel. I haven't acquired the bike just yet, but if I do, for sure I'll check it out as you suggest. My problem with a rebore is cost and who does it. Up here in the wilds of Aberdeenshire you may appreciate that such delicate machining is something of a rarity amongst the tractor fraternity and the lump hammer appoach taken by the oil boys' machinists is not particularly encouraging- I should know as I am one of them....I'll give it some thought when I look down the bore for those tell tale wear marks!
