During use a chain will stretch (i.e. the pins will wear causing extension of the chain). To measure how much a chain has stretched, put the motorcycle in gear and rotate the rear wheel to tension the top strand of the chain. … Misalignment of front and rear sprocket is a major cause of rapid wear.
How tight is a motorcycle chain supposed to be?
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. Step 4 To adjust the drive chain, loosen the axle nut a couple of turns . If all you have is a short wrench, you can stand on it to get the nut loose.
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.
Do chains stretch?
Chains do not stretch, in the dictionary sense, by elongating the metal by tension. Chains lengthen because their hinge pins and sleeves wear. Chain wear is caused almost exclusively by road grit that enters the chain when it is oiled.
How much do bike chains stretch?
The number most commonly agreed on for a worn chain is one percent elongation between links. In reality though, you want to replace the chain before this point. So therefore anything past 12, 1/16 inches (0.5 percent) would be the time to replace a chain.
Can you use WD40 on motorcycle chain?
If the chain is wet using a water displacing lubricant like WD40 is better than proper chain lube. It will chase the moisture out instead of sealing it in. In dirty conditions you do not really want sticky lube on the chain rollers where it contacts the sprockets. … Lube the chain before you wash the bike not after.
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.
Can you adjust motorcycle chain without stand?
If you lube your chain regularly, you will probably not need to adjust it every time you return from a ride, but as a chain nears the end of its usable life, you will need to adjust the slack more and more frequently. Although a rear stand is not required to adjust your chain, it will make the process much easier.
Why is my motorcycle chain clicking?
Towards the end of their life chains acquire several “stiff” links which don’t work smoothly over the sprockets, they can cause the characteristic clicking noise.
What causes chain stretch?
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.
Can chainsaw chains stretch?
Chainsaw chains stretch and become loose during operation. … Chainsaw chains stretch during normal operation and begin to sag on a saw’s guide bar. If a chainsaw chain is allowed to become too loose, it can easily come off the bar during operation and create an unsafe situation for the user.
Do gold chains stretch over time?
The interesting thing about box chains is that they stretch more than any other type of chain (because of the way they’re made). A 20″ chain in a couple of years could end up being 30″ (gold being very malleable can stretch quite a distance). … Once a box chain gets stretched and thin, there is no way to fix them…
How do I know if my bike chain needs replacing?
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.
How do I know my bike chain size?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
How long does a motorcycle chain last?
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.
