I have a 2005 Polaris sportsman 500 H.O. and i was just wondering what the rmp range at idle should be and whne your going about 20mph as of right now my soo ho is at 900rpm at idle and at 20mph it is 4500rpm is that normal or not i thought that was kinda high please some one let me know thanks.

 

Welcome to the forum Amped. My '06 500 EFI always idles at close to 1150 so I assume it's normal to get that high. 900 rpm doesn't sound fast to me, but your manual should say.

 

Thanks for the info if you ride your 500 ho soon could you let me know what the rpm is at 20 mph thanks my ranges from 4300-4500 thanks

 

first idling should be 1150 +,- rpm's . depending on which range your in and how much load is on the bike will make a differnce. i wouldnt say that it was not normal. you should be able to tell if the belt is slipping to make it rev up too high imo.
