I "feel" like I may have lost some torque on my Raider. I don't know this for certain. It's not sluggish by any means but I'm not feeling that same rush when I pull on the throttle. I put new plugs in, new air filter and tires, oil change and gear oil changed. I've got Vance and Hines 2 into 2 Big Radius pipes with a Vance and Hines fuelpak. It's running fine. Maybe I'm just getting used to the bike. I don't know. Is there anything else I should be looking at?
