Replace your airfilter and clean the outerwear.

 

I agree. A dirty air filter can cause a lot of issues that may seem more serious than they are. You cant clean the stock filter. Your best bet would be to pick up a K&N. You can clean that as much as you need to. Its the last filter you will every need to buy

 

My sp is the early model 500,wish that I knew about the 04.5 at the time that i bought this one, so it has a 5.25 gal tank.While looking at it today I noticed that the exaust seamed to be a little black,so I am going to clean the air filter check the plug,try some carb cleaner.If i buy a kn filter will I have to rejet?

 

Want to talk gas milage?Try my 400 Sportsman dont have a speedo anymore but when I get more the 10 miles from my truck I take a spare gas can. Now my Scrammy seems to go forever.[img]i/expressions/face-icon-small-shocked.gif[/img]

 

No need to rejet for the K&N

 

I went on a 40 mile ride today with the ground covered in ice and snow. I had alot of spinning and was in 4x4 the hole time. when I went to the pumps, I topped it off with 2 gallons. I don't think this is too bad considering the machine is new and has less than 40 hours on it. By the way, I ride a SP700EFI. C-Ya

 

I get around 60 miles on the tank full, but when riding mud / rock climbing i've got only 20 miles on a tank ... but thats alot of spinning, tipping, and idleing.

 

I went on a ride in the summer with my stock 2004.5 SP500H.O. on gravel logging roads doing a constant 50 to 55 MPH and got 65 miles when the low fuel warning lit on the display. That was in 2 wheel drive, high range with about 25 to 30 hours on it.

 

I ride hard with aftermarket exhaust,jet kit and air filter. Plus my clutching set up makes the motor rev about 400 rpms higher then stock. I get about 75 miles to a tank.

 

Running rich will effect your gas milage(use more fuel). Take a look at your sparkplug and see if it's a dark color. If it is, lean your carb out till the plug becomes a tan color.
