They look like nice engines. What would you buy? No rush because I have a running engine. Is the Dax a 40mm intake opening like the zeda80?
 
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.

 
Watch these 2 videos

That Zeda one looks like the A80 in the video. I personally prefer the PK80s over the GTs but I have never tried an A80.
