I have never seen an EVO engine apart, so I should say my opinion is of the current Magnum engines. They do not do many of the small things to improve performance and refinement, but otherwise fairly well built. TT does.
To me, all Thunder Tiger does more than Sanye are aesthetic things like polishing the name on the side of the crankcase, polishing the upper periphery of the venturi, etc. It does look good, but it doesn't make it a better engine, as far as I'm concerned.
Now if somone wants to take pictures of other mechanical items (machining, etc.) of the internals, I would be glad to look at them and learn something new.

Howdy Ed the magnum I have doesnt have a machined crankcase for the the bearings. I would have prefered that instead of a nice machined ring around the outside of the head. Having said that its about 6yrs old and runs like a champ. Cheers from the pope
