hey.. first off this atv(2006 polaris hawkeye 300 4x4) is for my wife and i just picked it up used with about 20hrs and around 35-40 mi it sat inside most of its life....I live and will be useing this atv at aprox 9500 ft in elevation so i jetted the carb per. polaris specs. it starts and runs good. And i get all the rpm i need but it wont go faster than 20 or so mph. i opened up the drive and it has yellow rollers up front and a white rear spring in the secondery clutch. keeping in mind that my wife will be riding this atv along side me on my 2013 500ho sportsman. I would like to know how i can get back stock performance or as close as possible. by tuning the clutch for altitude. What color rollers and rear spring.

 

Welcome
