Re: Hello from Tennessee
Welcome to the forum. You've found the right place to get you on the road.
It looks like you made a good deal. The bike certainly has potential if you take your time and do it right. I see nothing of great concern. You have a good start.
Which bolt is missing from the engine? Probably a mount fastener? If it is broken off in the case there is a lot of good information here on ways to remove it. Broken fasteners are common and mostly due to people over tightening them.
Curious about your trip to Denver. Did the owner of the bike you mentioned say he was a member of our forum? There are a few Denver area builders who are members. Maybe I know your friend.
