Dennis,
This is a good question,
It falls down to accessories and how the machine is set up. When you look at the illustrated parts list for both units, they are just about identical. The only major component of the engine that is different is the exhaust, while both have Catalytic mufflers they are different part numbers. The crank, the piston as well as the gear head are the same in both units.
I hope this helps.
