New 600 motor ?

[polarisj]

I here there is a new motor for the rmk 600 for 2012. Does any know what is different about it compared to the 2011 and will it be in the 121" skid?

Rush and short tracks get the 4 injector 600..The mountain sleds get the 2 injector motor which is the exact same system as the current PRO RMK 800's.

The motor is the same.... different porting, fuel map.

Will it have more power or get better fuel economy, what is the advantage with 2 injectors compared to the 4?

My wife loved the 600 Pro that she got to demo over her 2007 600 Swithback so much that I just Snowchecked a 600 Pro ES today for her. She also let me Snowcheck a 800 Pro 155 ES in orange. I had sold my 11 800 Pro already before she had a demo ride. It will be a long summer !

Poo says more power, but I doubt it much, tho if the CFI 4 to CFI 2 800 change is any indication, better on fuel, and probably lower emissions. I'd guess it is MUCH easier to map for altitude changes, no injector cutover, parts commonality with the 800, etc.
