Happy Wednesday! I recently bought a custom built '99 FatBoy with an EVO. I'm changing the cam to an Andrews EV 27 along with the bearing and tappets. Question are: 1) the cam I pulled has the letter N only stamped on the end. Is this a stock H-D cam for the EVO? 2) When I pulled the cam, there's a very thin washer that sits between the cam end and the bearing...I don't recall seeing this in any of the videos I've watched on replacing the cam. Thoughts? Thanks so much.
