I was a little surprised that I barely got my 2006 Sportsman 500 HO up to 50...I only had a bout 1/2 a mile and it seemed like it could have gone slightly faster yet, I was surprised. Only 800 miles on this, will a valve adjustment make a difference?
The last time I checked mine (08 500 HO) it would do 62 mph. That was on the speedometer not a GPS and that was in a little less than a quarter mile. It was fast to get to about 55 but builds a little slower after that. When I checked it I only had about 175 miles on it and I had just had the first service done. Where I ride mostly there is nowhere to get that kind of speed so I have not been able to check it after that, but It seems to have a little more pep to it after I got it fully broke in. I highly recommend the Sea Foam also. I use it in every 3rd full tank of fuel I put in. A good example of what it can do is that I have a 01 325 Magnum with approximately 8000 miles on it and have never had a fuel system problem, I have never changed a filter or anything fuel related since I got it in 02.
I had mine 07 out along side my buddys grizzly and my speedo said 55 with just a little throttle left my buddy's speedo said we were running 60 so I'd say 60-65 would be a good ballpark

I got my 08 Touring up to 55 today on a quarter mile strip of blacktop behind my house. It may go faster than that, but I get a little nervous going that fast and backed off. I'm not as daring as I used to be...
