I used this manual when I was young to maintain my GB400, and I couldn't have done engine restoration or adjustments without it. - Brand: Honda - Model Name: GB400, GB500 - Type: Service Manual - Language: Japanese - Year of Publication: December 1987 (Showa 62) There are some page folds, but it's in good condition without missing pages, tears, or oil stains. This is a one-of-a-kind used book, so please understand that all sales are final (no returns, no refunds, no exchanges). Thank you for looking.
