The rule of the thumb says that the exact tightness of a chain will only let you move for about half an inch. Now, if the chain is too loose, then you need to tighten it. If you cannot even move the chain, then it is too tight, and it needs to be loosened.
How tight should a chain be?
Is it coming undone while you ride? Check your chain out. It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up.
How tight should my chain be on a single speed?

Can you over-tighten a chainsaw chain?
There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don't over-tighten the chain as this could cause it to break.
Can a chainsaw chain stretch?
It's perfectly normal for a chainsaw chain to stretch after regular use. But, if you allow your chainsaw to become too loose, it can easily come off and pose a dangerous situation for you. A chainsaw chain stretches and loosens from tension and extreme friction.
How much will a chainsaw chain stretch?
Chainsaw chains stretch considerably after their first run, with about 1/100 of an inch per link. A longer chain with 75 links stretches around 0.75 inch. A shorter chain will still stretch almost half an inch.
Why does my chainsaw chain keep loosening?
Chain Not Set Properly
One of the most common reasons why your chain might be coming loose is because it was not set properly. When you go through the steps to tension your chain, you need to finish those steps by setting the tension so it won't change as you work your saw.
How often should you tighten chainsaw chain?
During a typical afternoon wood-cutting session that lasts 2 to 4 hours, you may need to tighten the chain two or three times. But, it's quick and straightforward since you don't need to disassemble the saw. Keep a scrench nearby for tightening.
How long should a chain on a chainsaw last?
The lifetime of a chainsaw chain has no fixed limit and depends on usage and maintenance. The chain should last many years; 5-6 years should be no problem. However, if the chainsaw chain is used properly and taken care of, it can last way longer.
What makes a chainsaw blade dull?
If the logs that you're cutting up are muddy, then perhaps that is the sole reason why your blade is dulling too fast. It won't be hard to notice whether the wood that you're cutting is dirty or not. The dirt and mud can be a factor that will cause your blade to dull.
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.
Can you tighten a chain?
A loose chain will only get worse over time, though, so you'll want to fix it to avoid further frustration. Can I tighten it myself? You can tighten your bike chain on your own. Keep in mind that the process is different depending on if you ride a single-speed bike or a bike with a derailleur.
What does a loose motorcycle chain feel like?
Motorcycle Chain Tug
Another symptom of a loose chain on a motorcycle is a chain tug, a tugging feeling you feel when the bike keeps steady RPMs in a lower gear, which is another symptom of a loose chain.
How do I know if my chainsaw blade is dull?
When cross cutting (against the grain of the wood) a dull chainsaw chain creates fine sawdust instead of coarse strands. The saw is producing smoke even when your chain is oiled and the chain tension is correct. The chainsaw produces an uneven cut. This could mean that your chain has dull cutting teeth on one side.
Why is my chainsaw bar smoking?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
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.
Can I use vegetable oil instead of bar oil?
Effective – Vegetable oils have natural properties including good lubricity, resistance to shear, a high flash point, and a high viscosity index. These qualities lend themselves to chain lubricant requirements similar to petroleum-based chain oils, and do not contribute to chain or bar wear over time.
Why does my chainsaw chain stretch so fast?
Another highly significant factor in chain stretch is the accumulation of dirt particles between parts of a chain. These particles form a paste with existing petrochemical lubricants, and they will cause pins, rollers, and bushings to lose material rapidly, again resulting in an overall elongation of the whole chain.
Do chains stretch?
Contrary to popular belief the chain isn't actually stretching at all; it is the pins holding the links together that wear and elongate, effectively lengthening the pitch of the chain. The holes in the inner and outer link plates, through which this pin sits, also enlarge over time.
Should you run a chainsaw at full throttle?
Engine Protection
Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised.
