Last night i picked up a 2000 Blaster for $220. its in rough shape with no compression at all. got it all stripped last night and started cleaning things up. once i opened up the motor i found it to be really clean for a no compression motor. i measured it all out and the piston and bore both measure right around 66.5mm but the rings, off the piston with no pressure squeezing the closed measure 65.5mm. could i get by just ordering proper sized rings? This isn't my first blaster (or 2 stroke) but I've never been this far inside a blaster. If I'm right stock bore on a blaster is 66mm? has this one been bored? i am almost tempted to take it to a machine shop but I'm cheap. any suggestions?
