04 Dyna with about 27K on it. Wife and I were running some errands in Vegas yesterday. Bike was running great. I had already done about 80miles that morning. We parked went into a store, came out and jumped on the bike to go down the block. First gear started just fine but then, lost power but the engine was still reving. Did this a couple of times. I changed gears and it would happen again. I made it down the block and parked. I revved the engine in neutral and no problems. Feels like I was pulling the clutch and letting go right away while revving up. I've never had this problem. I don't have a tach on the bike to see if it happens at a certain RPM. Any suggestions?
