Hi,
Shoguns were not that popular in SoCal but you would see some periodically. I really didn't know much about the company when I bought a Shogun Kaze in the mid-1980s. It was sold a s"cheap" funny bike (TT bike) that had a 24" front wheel. It came with Shimano 600 components.
I bought one fairly cheap and stripped the components off of it and put them on another frame which I sold. I then put a mixture of Italian (Gipppieme) and Japanese (Sun Tour) parts. I still have the bike and raced on it a recently as 3 years ago. Right now it's in a slight state of dis-repair but I've been thinking of putting it back together and selling it.
Don't have any photos of it right now.
