What happens if your chain is too loose?
The major symptoms of a loose chain include chain teeth skipping over the sprockets, uneven transmission of power to the wheel leading to jerky wheel movements, chain lash and the chain slapping the swindle arm, and in the final case, chain coming off the sprocket.

What happens if bike chain is tight?
With a chain being too tight, that causes tightness and stress on the rear suspension. This can be quite uncomfortable for the rider. The chain itself will also become worn out much more quickly.

One of the most common reasons is a new chain on an old bike. Older bikes obviously have older and more worn-down components. Placing a new chain on these worn-down parts can cause the chain to jump and slip around as you ride. All of this motion will eventually cause the chain to loosen up.
How tight should my chain be on a single speed?
Chain Tension
There should be approximately one half inch of movement in the chain up and down at a point half way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again.

Why is my motorcycle chain tight and loose?
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.
How often should you tighten your motorcycle chain?

How often should you replace bike chain?
The 2,000-Mile Rule
To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike's chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.
What causes a chain to stretch?
Chain wear is commonly referred to as 'chain stretch', because the chain's pitch grows in length as it wears. This is the most important type of chain wear, and the growth comes from the bushings wearing with the chain pins. Overtime, the inner diameter of these bushings increase and the pins groove out.

Why does my bike chain slip when I pedal hard?
The most common reason for the chain slipping is that the cable is stretched, then the solution is to tighten the shift cable. If the problem is that the chain is too long they will need to shorten the bike chain. If there is any damage to the sprocket, derailleur, chain, or cable you will need to replace it.
How do you tighten a bike chain with a derailleur?
Select the highest gear (smallest sprocket) on the shifter. Pull the cable as tight as possible at the derailleur and attach it to the body via the cable anchor. Once you've done this, select the third gear on the shifter and gently pedal forwards to shift the chain.
How do you know if your motorcycle chain is tight?
Now that your bike is stable and off the ground, you can check the chain tension. The correct amount is usually printed on the swing arm above the chain, and can be measured with a tape measure by placing the tape against the arm and reading the distance between the two.
How do you know if your motorcycle chain is bad?
At the far back end on the rear sprocket, pull the chain away from the teeth parallel to the ground. A new chain will barely move. If you can pull it back to expose half a tooth or more, you need to replace the chain.
Can a loose chain cause vibration?
Re: Chain/sprocket wear causing excessive vibrations? Chain getting tight then loose then tight then loose means time for new chain and sprockets. Excessive noise or vibrations indicate time for new chain and sprockets. Things like this indicate time to replace the chain and sprockets.
How long should a motorcycle chain last?
On average, you can expect to replace your chain and sprocket between 20,000 to 30,000 kilometers, less if you ride fast and hard. However, if you spot any damage to your chain or sprocket, it's better to just go and replace the prematurely-worn part right away.
