1966 - 1977, CT90, S90, C90, CD90, CL90, CL90L Honda Shop Manual.
In the early years, Honda used to "bundle" similar models of motorcycles together in one shop manual. The above manual was published in early 1977 and was the last of the bundled shop manuals to include the CT90. The following years had a dedicated shop manual just for the CT. This is an Adobe Acrobat PDF documents of 179 pages. If you have a slow internet connection, it may take a long time to download and open on your screen. I'd recommend that once you open it up, look to see if you can save it to your hard drive.

Two different locations for the same Honda Shop Manual. These are Adobe Acrobat PDF documents of 200 pages. If you have a slow internet connection, it may take a long time to download and open on your screen. I'd recommend that once you open it up, look to see if you can save it to your hard drive.

Technical Book Sources
Even though this section has "listed internet sources" of where you can find and buy technical books, there is always a possibility that you can find a better book source. So, just do an internet search using some "key words" to describe what you want, on either Google or your other favorite internet search device. Some books are not available on the common internet book sellers, so searching for them on your own will reveal other book sources.
