My aunt brought this to me earlier this week and wanted me to try to find out more about it. She bought it brand new in the 80s and kept it indoors ever since. I aired up the tires and they both hold well. It's all there and I think it has all original parts, even the tires say shogun on them. I know nothing about Japanese bikes and would like to know more about it. Is it worth fixing up? Any information would be helpful.
