Most all of the Hondaline 300R parts are gone, you may be able to find a piston though somewhere. They only made a few oversizes for the 300 kit. I also heard a Odyssey 350 piston is the same, but cannot confirm. You can also have your cylinder sleeved for the L/C big bore 330? (I believe) piston. If you get the right set-up for the 300 kit, the motor can be a real beast. I have heard a lot of guys running a carb from a 85-86R at a minimum, or bigger. I know there is a ton of info over at air foolers dot com . I dont mean to detur you from this site, as I love 3ww. Over at
s thats all they do. ---- Jon.
