I have a 2003 Softail Springer with 22645 miles on it. I was riding on the highway then took my exit and came to a stop at a red light. After it turned green I went to take off my RPMs almost red lined with out really rolling it hard but the bike had no power behind it. It was like a 50cc scooter trying to go up a steep hill with two people on it. It didn't matter what gear I was in. The only time it gained speed was downhill. Any idea what it could be. No check engine light or oil light came on
