Default Changing Crank Seal

It looks like I may have to change a crank seal on my bike. Couple of questions:
  • is it possible to change the crank seal by removing the rotor, but leaving the inner primary housing installed?
  • instead of changing the transmission sprocket, it is possible to change the compensator sprocket to change the gearing (something like going from a 34 tooth to a 32 tooth)?
  • Which chain tensioner should I upgrade to as long as the primary chain is off.
  • Anything wrong with keeping the stock compensator? Eventually I will do engine mods, but nothing crazy (110 HP target).

1. Yes you can change the seal that way

2. Yes but it's harder because there are less options and pretty much not a lot without changing the whole compensator

3. Baker attitude adjuster or Hayden m6

4. I don't know because you didn't tell us anything about your bike. Like what model it is or what year

2008 Street Bob. Engine is stock for now (96). Will eventually upgrade to a 106, w/ cams, ported head, exhaust, etc. Get somewhere in a 110 Hp/ft.lb. ballpark.

The stock compensator on my 09 had issue at about 20k miles. I would change it.

For the chain adjuster, I would stay away from Hayden. I've had their shoe explode in my primary. They blamed me. Went to a baker attitude adjuster, 40k miles later no issues.
