After inspection, again slowly move the ATV forward
until all the chain slack is on the top side of the chain
and inspect the deflection. Repeat this procedure
several times to check different spots on the chain.
The chain is correctly adjusted when the tightest
portion of the chain itself has approximately 3/8 in.,
(10 mm) of deflection. It’s a common characteristic of
any chain to have one or more tight spots in the chain.
Therefore, it is extremely important to check chain
deflection in several areas of the chain to ensure
deflection is correct at the tightest point.
