Thanks, I'm from northwestern pa in the US. I pulled apart a couple motors and matched up different brand base gaskets and noticed that they didn't quite match up the same. One looked like it was blocking the ports a little. I'm actually putting this motor together myself and am just trying to get some ideas on gaskets and whatnot. Steve told me that they used a .060 gasket but I thought that seemed kind of thick with the 25cc domes. I only really plan on taking the motor to a builder to get the clearances checked. Thanks for the help dirtydownunder

I'm building a 421 using the athena cylinders because I got them with the quad but I dont know what size base gasket to get. Is there a bigger gasket for that 68mm bore or does it use the same size as the 64mm? I'm trying to find out if one is cut out more for that bigger bore cylinder or not? Also I'm trying to figure out what thickness I need. I'm getting a hot rods 4mm stroker and 25cc domes to fit the athena head. I also plan to get the case port matched as well as a mild port job on the cylinders for mid to top end. im thinking around +4 timing and I usually cut sunoco 110 with pump 87 at 50/50. My elevation is 1300-1400 I found the 25cc domes for the athena head on this web site http://www.twostroke..._engine_kit.htm
