Rear Drive Chain Slack

Check the amount of chain slack in three different locations by moving
the vehicle slightly forward to gain slack at the top side of the rear
chain. Measure the chain slack at the tightest of the three positions. At
this point the chain should have 3/16"-3/8" (5 mm - 10 mm) deflection.
NOTICE: Adjusting or operating the ATV with improper rear drive chain slack
can result in severe damage to the transmission and drive
components. Always make sure the slack is within the stated
specifications.
