Dax sells PK80s They have the short connecting rod and use the type of piston with the wrist pin location low on the piston. The Zeda80 uses a long connection rod and uses a piston with the wrist pin location in the middle of the piston.
What would you guys buy? I do not how the connection rod and wrist pin effect performance or engine life. I will google this weekend until I have a basic understanding.
Starting at 5:22 he starts showing the intake opening. It looks much bigger than the one I have.
