Atv not going it's potential speed
 

I have a 2006 Polaris ATV 500 HO. I notice I can just barely get it up to 50mph on flat gravel surface. shouldnt it be able to go a little faster than that? say more like 60 mph?

Belt and clutches area sounds like the first area to look at. May be as simple as a glazed stretched belt that may be slipping.While you have the clutch cover off blow all the belt dust out in an open area. Usually they make a cloud of dust.

Ok. So you do agree that the sportsman 500 HO can go faster than that?

Yep about 57,58 mph as far as I can remember,but every machine was a little different. Had several people that bought two new ones at a time that would say one of their machines was faster than the other one..

Ok. I might have someone take a look at it. hopefully that's all it is. Thank you for your input

What size of tire is on it? If someone changed tire size your speedo will be out.

Not sure what the tire size is...I bought it off someone privately a month ago. It only just broke 1000 miles on it so I'm guessing it's still the original tires from when it was bought. Again I'm not positive though

It will say on side of tire just like a car tire
