We know they can get 'em done fairly quick when they need to. I think they started on mine on a Monday afternoon or Tuesday morning and were done with the cams, oil pump, lifters, etc. plus a dyno tune and 15,000 mile service by Friday afternoon (thanks in no small part to JR keeping track of things). This included about 48 hours down time waiting on a new rear cylinder head to be air freighted in after porosity was found.
Myself, I can't wait for Mark to get his bike back, but if there's no timetable the bike needs to be done in (unlike when mine was there), I can see them doing it at their pace. When I had the Brembos installed last winter this time, I think the shop here had the bike for over two weeks under similar circumstances. It's probably a job that could've been done in less than a day but I was in no hurry whatsoever for the bike at the time.
