I have a cusotm Harley Chopper built in 2007. The numbers on the front lowere left and right of the crankcase are AB07H5932. Can anyone tell me how to decode this to determine what engine I have.
Thanks
Tom

The AB crosses to a Police model Electraglide (FLHP), but the 0 doesn't cross with any engine size and the 7 is the start of the serial number unless it is an S&S or other aftermarket engine.
These aren't HD or SnS cases. Probably ultima but could be Sputhe, Delkron, or some other case.. Since it has a Ev27 cam, I would suspect that it's probably 80 ci.. Cylinder deck looks to be standard so it can't be much more than a 96 ci motor.
The Ultima has a smooth finish about .5 inch on both sides were the cases bolt together. The cases on this bike look like they are walking or just have a bad cast. Edit polished Ultima cases don't have the .5 inch finish. So it could be Ultima
