That definitely seems to be the case with this bike. It was very well loved by whoever bought it originally, and the seller I'm getting it from said he really only used it for fun around town and to go to St. Cloud.
One thing I did, and many others do as well with an older bike, is to replace all of the old fuses and basic bulbs with new ones. Old fuses can be brittle, and old bulbs can be corroded and brittle too. I also used a small wire-brush on my Dremel and lightly buffed out the sockets for the turn signals and brake light bulb. They weren't bad or corroded, but it sure didn't hurt. I also did the same (very carefully) with the standard automotive-type fuse holders.
Weak electrical connections are quite common on 38-40 year old motorcycles, regardless of how they were stored.
