I wrestled the motor into the frame while on it's side. I couldn't seem to get the front engine mounts to line up with the bolt hole in the engine, so I attached the back side brackets loosely and righted the bike. Still no luck. I got the engine tightened up hoping the back side brackets would line up the front but still no luck. I loosened all the mounting bolts to see if I could wiggle the engine into alignment and guess what... No dice. This is probably a two man job. After 2 hours of sweating and swearing, I called it a night. The motor looks nice back in the frame though!
