Quick Answer: What causes motorcycle chain tight spot?

The most common cause of chain tight spots is that your sprockets are not as concentric to the wheel or gearbox output shaft as they should be, IE running “out of true”. This can be due to wear, poor quality sprockets or chain, or poor fitting.

Should a motorcycle chain be tight?

Too tight is as bad as too loose, but it’ll only take minutes to get it right. You should check and adjust your chain every 500 miles (805 km), and more often for a dirt bike. … 1.2–1.6 inches (30–40 mm) is typical for streetbikes, while dirt bikes may need 1.4–2.0 inches (35–50 mm) of slack.

Will a new motorcycle chain stretch?

A new motorcycle chain will appear to stretch during the first few rides after installation. However, a chain should not stretch too much immediately and might be defective if it continues to stretch or needs to be constantly adjusted.

How often should I lube my motorcycle chain?

A motorcycle chain should be lubricated every 300-600 miles to ensure peak performance and a long life. Lubricate the chain after riding, not before. This allows time for the solvents in the spray to evaporate before the bike is used again, and lets the lubricant penetrate the link properly.

How many miles does a motorcycle chain last?

Don’t clean and lube your chain, replace it more often. It depends on how much rain/sand/grit you ride through in addition to your efficacy and frequency of chain cleaning. I often got 10,000 to 15,000 on a liter bike chain. I often got 20,000 to 25,000 on a VStrom 650 chain with a chain oiler.

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.

Why do bike chains 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.

How much will a chain stretch?

The maximum allowable wear elongation is typically 3% for most industrial applications, depending upon sprocket design. In drives having fixed centre distances, chains running in parallel, or where smoother operation is required, chain wear should be limited to approximately 1.5%.

What happens if motorcycle chain is too loose?

If the chain is too slack, it can skip over the tooth in the sprockets, This skipping over of teeth leads to uneven transmission of power from the engine to the wheel. As a result, the speed of the motorcycle will unevenly oscillate without any intervention from the rider.
