When my '05 was new, the shocks leaked. I used a compressor to air them up, 75 miles from home. Went to the dealer, and I was told that since I used an air compressor, my shocks wouldn't be warranty, and I needed to buy a pump. I said BS. (It was only a loose hose connection). I purchased Harley's pump and it works great. I use 20-25 psi with bike loaded. Good luck.
