Hi I picked up a 2006 Street rod that was abandoned (lien sale) as a project. Got it home and started cleaning it up. Tried to start it and just clicked. Got new battery clicked again. Pulled plugs and raised bike on jack and tried to turn rear tire in high gear and no joy. Got a socket and turned engine by hand and no movement. Put MMO and PB in the heads and let soak,got it to free up a lil bit. Worked it back and forth and was able to get 2 full counter clock wise revolutions. Then locked up but not fully. It will turn left about 1/4 turn and stop then right about 1/4 and stop. You can hear it hit something. Maybe heads. Just curious if you have any ideas. I will be pulling the motor shortly to pull the heads soon.
