with the new cfi and efi you are wasting time and money with reeds unless you are doing other mods to help them pump more air
Also next year for 2012 the 600, and 800 Rush will have direct injection.
The new 2012 4 stroke will not be in the Rush. It will be in the IQ, or maybe a new style.
All stock 800 2s fast all 150-160ish hp 4s fast. Who cares?? I don't care at all who or what is the fastest I'm not racing just power crusing twisty WI & wide UPMI trails. Interested in MPG, engine problems, out of box HP, oil useage,handling,wind protection,ski darting on board storeage & ease of shock set up for bump ,wash board & G bump handling? Forget the who is fastest stuff go to radar runs for that.
