No, OS is not Italian. I believe it is Japanese. Some other engine that I think are Japanese too are the RD Logics' Team Infinity engines (512 .12 5port Katana, 521? 5port big block Samurai, I cannot remember which other models came from the Toki factory). I cannot find any more of these engines before. I have a 512 Katana and need to rebuild it. I cannot find a replacement piston and sleeve rebuild kit anywhere.
