You asked: What causes motorcycle chain to stretch?

The sprocket teeth often start to shape into a wave pattern. This causes chain and sprocket to wear unevenly. In an attempt to balance out the chain stretch the sprocket wears and adopts to the new spacing of the chain, which in turn will accelerate the stretch of chain links that are not yet worn.

Why does my motorcycle chain keep stretching?

A motorcycle chain that keeps getting loose is usually caused by the rear axle or chain tensioning bolts not being tight enough. It can also be cause by a new chain not being worn in enough, worn down sprocket teeth, having too tight of a tension, or having the wrong size of chain installed.

What causes a chain to stretch?

Its elongation is caused when material is removed from the pins and bushings. The individual joints in a roller chain articulate as they enter and leave the sprockets. … This articulation results in wear on the pins and bushings. As material is worn away from these surfaces, the chain will gradually elongate.

What happens if motorcycle chain is tight?

When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. Ultimately, a tight chain on a motorcycle may break leaving you with no power.

How much will a new motorcycle chain stretch?

Fresh chains will only bend a couple inches over ~3 ft while I have seen a worn chain bend almost 90 degrees in the same distance. Edit: Also, properly lubed chains don’t stretch at the same rate as poorly lubed chains.

How often should you tighten your motorcycle chain?

You should check and adjust your chain every 500 miles (805 km), and more often for a dirt bike. It’s also a great time to look for kinks or rust, and to give your chain a quick cleaning and lubrication, too.

When should you replace your motorcycle chain?

But chains wear out over time and need replacing. So, how often should a motorcycle chain be replaced? In general, a properly maintained motorcycle can will last 20,000 to 30,000 miles, sometimes more. But, some last as little as 5,000 to 10,000 miles.

How do I know if my chain is stretched?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

Can you use wd40 on a motorcycle chain?

How do you know if your motorcycle chain is bad?

Other signs are worn spots on the insides of the plates which usually signal that the chain is out of alignment. Look for matching worn spots on the sides of the sprockets’ teeth. You want your chain to look like this. No daylight between the sprocket’s teeth and the chain.

Can you adjust motorcycle chain without stand?

Although a rear stand is not required to adjust your chain, it will make the process much easier. When your chain is cold, measure the slack halfway between the sprockets by moving the chain up and down.

Can chains stretch?

Although chains are frequently described as having stretched due to wear and use, the term “chain stretch” is slightly misleading. The phenomenon of chain stretch is more properly referred to as chain elongation, since it is not the case that the chain links themselves are actually getting longer.

How much can a chain stretch?

The maximum allowable wear elongation is approximately 3% for most industrial applications, based upon sprocket design. The allowable chain wear in percent for large sprockets with 68 teeth or greater can be calculated using the relationship: 200/N, where N is the number of teeth in the large sprocket.
