QUAD CHAIN ​​KIT REPLACEMENT TUTORIAL

Ce tutorial aims at you help replace chain kit of your quad thanks to the pics and explanations associated. In this example we used a KYMCO quad Maxxer 300, but the procedure remains the same for the other quads.

The chain kit is an essential element for the performance of your vehicle.

Its lifespan may vary depending on its maintenance (tensioning and lubrication of the chain), the type of driving, the quality of the chain and the sprocket, the cubic capacity of the quad and the number of runs. Generally, a maintained chain kit will easily be able to do between 30h and 50h or between 1500 and 2500 km depending on the external aggressions (sand, earth, mud, etc.) present during driving.

Several indicators should alert you when wear is felt:

- When you pull the crown chain, the latter is very flexible and play is felt between the crown teeth and the chain.

- The links of the chain are relaxed.

- The crown and/or pinion teeth are worn.

Finally, before any change of a chain kit, you must first make sure that other important parts are not worn: swinging arm pads, chain guide and rollers. It is important that these parts are in good condition when assembling your chain kit.

Valve clearance is part of routine motorcycle maintenance. You can do it preventive or for simple verification. The consequences can be serious; indeed, if the clearance is too low, there is a loss of compression. If the clearance is too great, the valve wears out prematurely.

Replacing a pellet (whether intake or exhaust) can be more tricky.
