My FXD and I were out riding when I strted hearing a winding sound and I lost power. I took the primary cover off so I could inspect the clutch. I replaced the clutch plates and friction plates and I still have the winding sound. I was told to put the bike in gear without the motor running and to push the bike to see if the primary chain was moving. I was told if it does not move that the trans main shaft is broke. Is this true and how much is it going to cost me to get it fixed?
