The chain, sprocket and pinion are three items that are essential to the well being of your motorbike. If not well maintained you will end up forking out a lot of money all too often to have them replaced.
 
Lubricate them often with a commercial chain spray (every five running hours/once month/every 300km). Spray liberally on the side of the chain that comes into contact with the sprockets. Ensure that you spray both left and the right hand side of the chain. Position a piece of newspaper so that you do not dirty the rear wheel rim as you spray. Use a second piece on the floor to catch any drips. Wait five or ten minutes before you wipe all excess oil off the chain. (This whole process is a lot easier if your motorbike has a centre stand) I find that an old sock slipped over my hand works the best. If your chain has been recently lubricated you only have to spray small sections. Spinning the back tyre will ensure that the rest of the chain is lubricated when it comes into contact with the sprocket and pinion. This is a task that is best done when you return home from your ride while the chain is still warm.
Bike chains are never taut but must be able to sag between 20mm and 40mm at the mid-point between the two sprockets. The sag is used when the bike suspension moves up and down over uneven surfaces.
If your chain is not an endless loop it will use a master link to join the two ends together. Check the condition of this link on a regular basis. Unfortunately replacing it usually requires a special tool to force it to separate.
 
Cleaning 
If your chain becomes very dirty e.g. after a long ride on a dirt road, leave it overnight. The crud becomes hard and is easily brushed off with a small steel wire brush the next morning. If you do want to clean it with a solvent do not use petrol as this dries out the small rubber O rings in the chain. Use a commercial chain cleaner, kerosene or diesel fuel as these are all oil based.
Chains stretch with time no matter how well they are cared for. You will know when the chain has stretched too much when you are able to pull the chain off the back of the rear sprocket.
 
IMPORTANT: 
We recommend installation by a qualified motorcycle mechanic. Always replace with equivalent chain and correct master link as recommended in the manufacturer�s service or owner�s manual. Failure to install a replacement chain and master link equivalent to those of the motorcycle�s original equipment type, size and pitch can be dangerous and result in serious injury and property damage.
 
DETECTING A WORN OUT CHAIN: 
Rust, kinks, stiffness, excessive stretching (1.5% for non-sealed and 1.0% for sealed chain) and abnormal rattling noise are all signs of a worn out chain, which can break at any time. Replace immediately if any of these conditions are present. In the case where even one O-ring or Quadra-X Ring is missing or damaged, the entire chain should be replaced immediately.
