I just bought a 2005 Rocket with 8000 miles on it and I seemed to notice some difficulty shifting into 5th gear the other day while under moderate acceleration. Later I had a similar issue with 3rd. It acted like there was no 5th to shift into. It seems if you accelerate slower it is fine. My gut tells me it feels like the dogs on the gears have some taper to them. I am just a little gun shy based on the huge list of issues I read on the site before I bought the bike. I plan on changing the oil in it this weekend first. I am not afraid to take it apart if needed. Any thoughts from the masters out there?
