Been a long project in the making but a group of guys have done the legwork to get new Wiseco 300R pistons made again for the Honda air cooled ATC250R Hondaline 300 cylinder kits. Sizes available are 76.50, 76.75, and 77mm. Pistons have some updates over the original cast piston to improve reliability. A group buy of 50 is needed to start production, quite a few orders are in. So if you have one of these iconic cylinders laying around bring it back to life with this setup. Here is a link to the Facebook project.
