Default RE: Are 2-Strokes Behind in Weight Reduction?
To answer my own question before I post it, I think cost is the reason.
The 2011 Ford Shelby GT500 engine is over 100 pounds lighter than the 2010 GT500 engine. Why? Ford used a process where the steel liner is actually heated and sprayed onto the cylinder walls on the 2011. The 2010 had steel sleeves. So why not do this for a model engine?
