It looks like the standard rusty bike that is in a million garages.
Not to sound mean, but it isn't anything spechial.
Missing all the original parts that resto guys look for, and doesn't have anything stand out that the performace guys want.
Like I said, I'm not putting it down, but you still have not really given much info.
The question isn't if it is a good or bad bike, but if it is a good or bad fit for you.
Personally if you are asking the web, then I assume this is a bad bike.
Spend the $3k on one of the solid runners that gets posted here every day.
All "barn finds" are $1000-1500 away from the road. And that is if nothing major is wrong. So the risk goes up if you don't know how to spot a good bike.
Also that number is for doing your own work, not paying someone to do things.
If you are well versed in these bikes, have spare parts, tools and time then I could see a guy paying $1000-1500 for it and having a blast (it does turn over and have a title right? If not it is worth less then scrap value)
