I have an 04 f7 efi sno pro with 900 miles ( Its all stock) mint shape. I'm going to ride with 2 04 mxz 600 ho's 2 yahama warriors and an one rx-1 . If we get any snow. What will it do agaist these sleds ?? I live in maine around sea level . I have heard different things i could do to my sled to hop it up. I do not want to compromise the longevity of the engine. Do you guys have any suggestions or comments about how it will do.

well I dont know, but I m running a Polaris Edge x 600, rode with 2004 f7 and it couldnt keep up with me at all. I just killed it and everyone says the f7s are supposed to be wicked fast, I also beat the yammy rx-1 seemed as if it was slower then the f7 so I think you will be able to beat the rx-1 and as for the ski-doos, I dont know about the 600s but i raced a 2000 mxz 700 and thought it was also slower then the f7. so I image you should have a good chance... if I was you I would try Gearing it a little bit.

Is your 600 stock? Was the f7 stock? Something does not sound right with this picture.

something aint right with that picture,,,, did the f7 know you pulled one of his spark plugs?? Are you clutched and modded beyond belief?? Did the f7 know you were racing??

As for performance on yours, clutch it,,, this will be your best bang for the buck. There are LOTS of them out there, but clutching will get you the most.

The guy with the Polaris 600 is sleeping and needs to wake up. Anyways i would call your local dealer and find out what they say. As for me i would put it on, if you want to beat what’s beside it!!!!!!!!!!!!!
