Chain Adjustment 

 

After the ATV has been used the chain will stretch as the ATV gets broken in and the 

chain will need to be adjusted from time to time. There are two studs that will take up the slack 

by rotating the axle housing. Loosen the two bolts by the adjusting nuts then tighten the adjusting  

nuts (see picture) evenly one turn at a time until there is only a half an inch of slack in the chain. 

If there is more than a half inch of slack then the chain will slap off the guard by the front 

sprocket and could cause damage to the chain or guard, or even personal injure or lose of control. 

The chain should be inspected and lubricated by an adult every time the ATV is going to be rode. 

If the chain adjuster can not be turned in so all the slack is removed then the chain should be 

removed and replaced. 

     

 

    

  

 

 

 

 

 

 

 

 

 

 

 

 

 

Valve Clearance Check 

 

After the first 10-20 hours of riding the 

atv; the valve clearence should be checked. 

During this time is when the most wear occures. 

To check the valve clearance remove the cover 

on the the intake valve first (see picture). Check 

to see if the rocker arm is loose, if not then 

there is a cover on the left hand side of the 

engine case if you remove the plug you can 

gain access to the crank shaft nut so you can bar 

the engine over and loosen the rocker arm (see 

the picture on next page). Insert a feeler gauge 

that is 0.004 thick and there should be a snug 

fit.
