For reliability go for the 600. I have never had a 600 motor go unless something bad got run through the motor. And the 600 fuelies run great with an slp pipe and can!

Do the 600 in 2010 have the 4 fuel injectors with the messed up maps? Or just the normal 2? Seem that's what the problems with the 800's

I think just 2 but i don't know. I have never had a problem with a fuel injected 600. And for the 800 i forgot to add look for a spacer plate in between the cylinder and crank case.
That means it has the bullet proof motor.

2010 RMK600 has the 4 injector system but there are no issues with the fuel mapping like the 800's.
