  • Before riding the go-kart, allow the chain lube to dry 5-10 minutes
  • Adjust the chain regularly (Watch Our How-To Video. Go-Kart Model: Mini)
  • Remove most of the slack but don't overtighten the go kart chain
  • Quality chain lube prevents the chain from wearing out so fast
  • Chain lubricant keeps chain adjustments to a minimum
