I have an '04 sportsman 600 that goes 55-60 on gravel. This machine will do about 40 on hard pack snowmobile trails or frozen lake with or without a windshield. Will anyone's go faster in these conditions or is that average? Thanks.

 

sounds about right compared to my stock 04.5 sp600.[img]i/expressions/face-icon-small-wink.gif[/img]

 

I have a 03 sportsman 600. On open road or gravel, I can get it to 50-55. On hard pack or grass 42 was max. I was able to get another 5mph replacing the factory air filter with a K&N. One day while cleaning the air cleaner, I washed the factory cloth cover that fits over the air filter and it. Before re-installing it, I put my mouth up to it and sucked in hard. Believe it or not this fabric resrticted the air flow. I left it of and just put the air filter itself back in the machine. I instantly got power in high rpm. I now get 60 mph open road and 50-55 in hard pack and grass all day long.

 

my 800 will hit low 70s [img]i/expressions/face-icon-small-tongue.gif[/img]

 

thats all the Sp600 does... thought it would be faster, my 500 can hit 60 and does 50 easy on hard pack like grass and cornfileds

 

They keep increasing the cc"s but they arn't going faster. Go figure.

 

yes i was really suprised to see the speed results i have never ridden on or with another 600 before and i would think that they would have been faster.

 

I have raced 700's and where neck and neck until around 50mph. The 700 will start to pull away. But 0-50 there is no differance

 

what i found odd is that the 500 motor and the 700 EFI motor would be neck and neck in a drag, but the 800 will beat the 500 by a few bike lengths. i dont get how that could be as the 700 and the 800 are the same motor exept bored out like 70cc's

 

The only thing ther accomplishing is higher torque in the upper range.
Take a look at my problem I just listed (4 wheel drive problem)
Let me know if you've herd of this before
Thanks
