THANKS MUTT. I DID NOT KNOW ABOUT SQUISH BANDS. A LOGICAL EXPLANATION FOR THIS CHAMBER GEOMETRY. IS THE INTENT TO DECREASE THE CHAMBER VOLUME AS WELL.?? DUANE TAYLOR ----- ORIGINAL MESSAGE FOLLOWS ----- . My guess is that the last owner might have been using a much larger TS-185 piston. You would need to open the diameter of the combustion chamber up, then machine that "squish band" in the chamber. All modern 2 stroke heads are that way. The band squishes the mixture to the center of the cylinder and makes for a much better burn. The head on my 61 Super 10 has a combustion chamber very similar to that one. The squish band varies depending on riding style. For racing, the band is generally 3/8" wide, for trials riding it is about 5/8" Wide ----- ORIGINAL MESSAGE FOLLOWS ----- This is for a 165 but the chamber is much larger. Was this for some low compression model? Has someone machined this out for some reason? What have I got? I have put it next to a "normal head for comparison. |
