have an 07 ultra with 10K mikes. Last year, have had to install a stage 1 and SE " slip ons, along with a parade fan and oil cooler to deal with the heat issues. This year, started getting the crank bang grind noise at the second startup , if within 15 minutes of shut down. So a lot of folks have been replacing the compensator for this, some have gone large CCA batteries, and some install compression release. A handful bump the bike before startup if the bike is already hot (apparently at shut down, the bike stops spinning just
before the compression stroke TDC, so bumping the bike in gear pushes it over TDC, and the starter can do a pretty good spin up of 2 rotations before the next TDC compression stroke.
so in googling around to understand the crank bang grind problems, it seems like the 07 and later bikes have a lot of early repairs. Lots of inner primary bearings, starter replacements, stator windings, voltage regulators, etc.
So what is your list of repairs to your bike.
