I was a little nervous about the lower bolt.So I used 2 jacks.I did not know if the engine would slip down when i pulled the bolt. I put the bike on a bike jack first.
Then put a piston jack with a hunk of wood om it under the motor. Guess I'm a little over causious with stuff like this.I spend twice as much time thinking things threw and
setting up than the actual job takes.Guess that comes from a life time of tool making. Anyhow the job was a snap.
bottom bolt slid in and out no problem.
