I have a 2006 Polaris sportsman 500 HO I was looking into getting a new CDI or something to add more power does anybody have any suggestions for websites to look at?? I can't seem to find any engine mods/upgrades to this machine... I also have a 2006 AC 650V2 and just received a new CDI and love the performance gains I got out of it... so all the help i could get would be greatly appreciated!!!!!!!!!!!!!
