Hey guy I have a 04 sportsman 700 EFI I feel like I have more than one issue going on ... (one) when I turn the handlebars the idle goes up about 800 to1000 rpms I think the cable is getting in a bind but I’m not sure. I think the cable is run wrong after the fuel pump got changed out.. ( two) the bike idles good but feels a lil sluggish, it does NOT miss or backfire ... but does not go ove 30mph and it will not take off very fast... this EFI and it is something new to me... the only thing done to this atv is a k&n air filter. It is clean as well and new spark plug... please help

 

My two cent is to replace that K&N with and oem or Uni foam filter.Even with and over wear they allow too much dirt to get through.First year model that did have problems on the throttle cable. Shouldn't have to replace it,but pop off the front panel,cut the loop holding the cable(if it's still there) and work around the left side in making sure the cable isn't binding as you turn the handle bars fully to the right side.If it's idling ok at that point you can add a zip tie loosely around the cable at the rear of the tank area on the frame.Check the intake manifold as they still had a habit of cracking,sucking air, under the clamp,plus change the fuel filter located behind the radiator area if it looks like it's never been changed.If that doesn't solve all the problems,you might want to check the belt and clutches. The manual can help also in the efi section plus help on repairs and service.http://polaris-atv.brssm.com/2004-Po...ce-Manual.html

 

Merry Christmas and thank you for all the help I will cut the loop it is still ther I cut off all the zip ties off the cable... does the cable run In between the gas tank and vent pipe for the CVt belt breather. And for the clutch and belt how would I check it out, pull the cover and run it and I will check the filter out for sure!

 

Cable runs inside the side panel,close to the tank then to the throttle body. The air exhaust duct from the clutch cover wrapped over the tank on this newer style system and didn't interfere(supposedly) with the cable. Plus on the belt check for wear,burn marks that could cause slipping. Any deeper than that is where the manual would come in handy.Depending on build date they had two different driven clutches. The belt used was the same.

 

Than you I will check into it .... right now I have the cable run outside of the vent tube from the belt cover right inside the cover.. I believe the bike was made feb 2004.... I will check into it

 

Yes it ran outside of the vent tube section that laid over the tank.

 

 

If the clutch system is causing the limiting the driven clutch is the one that's usually a problem. Also check the intake manifold. Carb and efi models were bad about splitting under the clamp and sometimes hard to see.Loosen the clamp, slide it back and see if the manifold has split. If you rule out the clutches,belt and intake manifold,the problem could come down to the limiter in the speedo itself.

Forgot also to make sure the that the throttle lever has only 1/16-1/8" free play. If too tight that also can cause it to idle up when you turn hard right. https://www.manualslib.com/manual/13....html?page=107 Plus if you need a cheap manual.2004 Polaris Sportsman 700 EFI Service Manual PDF Download
