Twisted iron - the happening, oxfordshire

Looks to be a good one and note interesting show category specifically for projects in the works

That sounds like one to try. 16th & 17th September, so I might actually have the bike on the road by then, but unfortunately their show day's on Saturday -no good to those of us that have to work on Saturn's Day.
Good to see some alternatives to the traditional bike rally cropping up. I spent my youth camping at rallies every weekend, but most don't seem to have moved on at all since then. Nothing wrong with warm beer in a muddy field, but a bit more imagination makes for a more interesting event I think.
I've linked it to the events calendar at the top of this page.
