So i have a 2005 polaris scrambler 4X4 HO. I have recently been riding when i started feeling my chain jump or skip.... I couldn't ride more than 2 meters without the chain slipping/jumping and me losing all power. My chain is fairly loose and also skips when i put the bike into gear. I hoped...

how do i adjust the chain tightness on 90cc sportsman 2006? it has too much slack in it and i need to tighten it a bit.
