Found out KTM changed the piston for just the 95 year and no replacement is available OEM of aftermarket. Looks like the easiest solution for a replacement would be to pick up a 96-04 300 or 360 top end and piston kit. The base gasket and stroke are the same. Is this swap really that simple? I'm not having issues with this bike besides some basic stuff, however I'm not sure I want to invest much time and money into a 2 stroke with a non-replaceable top end. OEM replacement rings are available only. My thinking is a top end on this bike is $200ish, plus another 200 for a used cylinder and head. If that's not feasible the best economic sense might be to either run it till it goes and part it or sell it now and pick up a 2000ish model.
