How do you determine chain tension?
To adjust chain tension, loosen the bolts that fasten the motor base to mounting angles on both sides. Tighten take-up bolts until desired chain tension is reached. Do not over-tighten. A good rule of thumb is 1/4″ deflection in the chain between the sprockets.
How do I know if my motorcycle chain needs tightening?
Push up on the bottom of the chain and note the distance between the full-slack (lower) position and the no-slack (upper) position on the bottom . 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.
How do you check motorcycle chain tension?
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 tight should Roller chain be?
It is important to maintain the proper amount of chain tension. If the chain is excessively tight, rapid chain wear and loss of lubricant will occur. If chain is too loose, excessive vibration and pulsation may occur causing chain damage. For normal drives, adequate slack should be adjusted to 4% of the chain span.
What causes a tight spot on a motorcycle chain?
As was stated, binding links are caused by rust and lack of lubrication. If they are in a section of chain that’s tight, it’s because the links resist straightening out when they are stretched between the sprockets and are still cocked as if on a sprocket.
How do you increase chain tension?
To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again. Then, loosen the opposite axle-nut, adjust and tighten, making sure the wheel remains centered in the frame. Re-check tension. A chain tensioner can make the process easier.
How big should the chain tension be on a motorcycle?
Email us at [email protected]. A: It’s temping to think the dealer is screwing this up, but if you take a look at the owner’s manual for the FZ-09 and FJ-09, they both list a chain slack specification of a scant 5–15mm. So the dealer is in the right even if it doesn’t “look” correct.
Is there slack in the chain on a Yamaha motorcycle?
For whatever reason, Yamaha has called for a chain spec that, we feel, will result in a chain with little to no slack in actual use. That’s bad for chain-drive bikes—hard on the chain, sprockets, and even the countershaft seal and bearings—and we’d never subject one of our own motorcycles to such treatment.
Why is it important to check your chain tension?
Checking and adjusting chain tension is a fundamental bit of maintenance, right up there with checking your oil and tire pressures. Very basic, pretty easy, and also really important! Run your chain too loose and it’ll slap around and may jump off the sprocket and throw you on your head.
Can a chain come into contact with the frame?
In our view, there’s no way the chain can come into contact with any part of the frame.
