Nice to have available but only STD size. We do appear to have a supply problem. While the 350 ohv are not suitable for large oversizes the 500 cc Ohv iron cylinder can take a bit more bore size increase. I would NEVER bore metal out of any cylinder to get more power as the strength is more important and you can't put load carrying metal back. A sleeve does not add strength in the up and down direction. It will help to hold the pressure but that's rarely an issue. Proximity of bolt holes is. IF you get too close to them they will cause more distortion and sometimes crack to the bore surface. Nev
