Hi, could someone advise me please of the correct off set for a 18" Borrani rim? which is fitted to my Ducati Mach1, which I am rebuilding. The reason I ask is, I have rebuilt the wheel taking the measurement from the hub and rim before the strip down and now I have fitted the wheel back on the bike it is not sitting centre of the folks. It is 2.5mm to far to the right as you look at the bike from the front. I am kicking myself a bit because I presumed it was correct before the strip down and you know what they say about presumption!

. I have placed a spacer between the folk leg and the brake plate which corrects it making it central, but the lug is not fully home, which I am not happy with

Can someone point me in the right direction?
