In situations like this the question should have been...."How much do you think it will cost me to restore this bike"? Once our members have weighed in with their estimates; then "HE" and only "HE" can determine whether it will be worth it. Ogy
I agree with that Ogy, but that wasn't what he wanted to know. Very few who come on here with related questions are interested in what it costs to restore, they are interested in what they can flip it for.
In this case, the roller suddenly ended up on a Sacramento Craigslist page for sale with no price attached, or for trade for a running mini bike. I don't see it now, but it was there right after this thread. So I guess it wasn't going to be restored at all.
Personally, I don't know why estimates of value aren't allowed. No offense intended to anyone, but it would be beneficial to see what others think of value for given machines, and what those machines end up selling for.
This would be superior to a person wrongly asking "what is it worth," or "is it worth restoring" and then the entire conversation going to PM's.
