My builder took about 8 or so for my bike ... so 10 sounds reasonable to me ... but "2003 Screamin Eagle Deuce 95" 110tq/113hp done for now" ... what you want ... a rocket ... ahhh, maybe its for the "work in progress" bike.
I was quoted 12 hours +/- when I was gathering info to do mine. Right now I've got 14 hours in doing it myself. I've been taking my time and doing other things along the way that I'm sure would not be done by the dealer.
10 hours +/- seems about right for someone that has done them before and has everything they need at hand.
With all fluids/filter, and clutch spring, including 12 mile road test, we see 12.5 hrs. If loaded with "hot toppers", or chrome covers, covering the chrome covers, naturally more.
