The 2010 Parts catalog shows the same cam in the Ultra Limited 103 as in the 96 in all of the other models. Have to give the dealers a chance to take some of your money
So the SE comp is the rear pulley shock system? What kinda money we talking about for that?
The SE compensator replaces the "weak" OEM compensator located on the left (drive side) shaft under the Primary Cover. The stock compensator weakness is what causes the 'bang' noise when starting.
Its purpose it to ease the shock load on the primary drive system similar to the way the Isolated Drive System (IDS) eases the load on the secondary (belt) drive system.
I believe the SE compensator lists for about $250.
