s90

Honda S90 tank for sale. Solid tank, surface rust good cleaning and paint this would be great. $100 + Shipping.

Does anyone make big bore kits to bring the s90 up to 125 or 150cc, similar to how TB sells big bore kits for the CT? I'm looking to get a little more power out of the s90 engine and I know lifans and aftermarket motors don't bolt up like they do on a CT. thanks for your help.

Hello All! Ive been a member here for a few years, but haven't really posted much. Thought I would introduce myself and show my new toy! So Im a college student just finishing up with my degree in Mechanical Engineering and I have a huge bug for vintage Hondas. The first one I got was a CT70...

Does anyone know of a forum like this but for the Honda s90? I'm trying to find resources for parts, and other people doing restorations on these bikes. Thanks very much.
