INOX lube in an injector bottle. Do an e-bay search.

 

Strange, my clutch is actually too easy to pull imo.

 

I've got an 09 Ultra too and stock clutch pull got hard to pull. I argued with the service manager several times about this and he told he and his merry band of experts in the shop say it was in specs. That was bullchit. I took it to another dealership about 30 miles away and that service manager said it was a no brainer: The cable for some reason was "bad" and replaced it and problem gone. Later I found the reason for the hard clutch pull and bad cable: my new Ultra ground wire from battery to frame was loose and the electric will use the clutch cable to ground the system and it melts the clutch cable in the process. Later I bought and installed a Recluse centrifical clutch system and now don't need the clutch when I stop and go into first. great for bumper to bumper traffic. still need the clutch for all other gears though.
