Can you change front sprocket without removing chain?
dietrichpfeifer said: No need to break the chain! If you loosen the chain up all the way you should be able to simply slide the sprocket off the shaft with the chain still wrapped around it, once you get the nut off of course. You’ll need a pretty good cheater bar and torque wrench to get the nut off and back on again.
Can you change just the front sprocket?
if you change just the front sprocket, it will wear a lot faster as the chain has worn a little so they don’t fit properly. I’d say you change them as a set: both sprockets and the chain.
When should a front sprocket be replaced?
If the teeth are sharp, the sprocket is worn. Look for indented wear around the circumference of the sprocket at and below the teeth that resembles the shape of the chain. This “shadow” wear indicates a well-worn sprocket that should be replaced.
What does changing the front sprocket on a motorcycle do?
The purpose of changing sprocket sizes is to alter the relationship between engine speed on your tachometer and road speed on your speedometer. Let’s say your motorcycle comes with an 18-tooth sprocket in the front and a 43-tooth sprocket on the rear wheel. The ratio is 43 divided by 18, which equals 2.39.
When should I replace my front sprocket?
A common rule is to replace both front and rear sprockets every time you replace your chain. This is a good rule to follow if your chain has lasted for it’s full life of, say, 15,000 miles. But, sometimes a sprocket replacement can wait in cases where you’re replacing a prematurely worn chain.
What happens when you change front sprocket?
Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too).
When should a dirt bike sprocket be replaced?
The time to replace sprockets isn’t after the teeth are severely curled or worn down to a nub. Or when the chain starts jumping the cogs. To maintain top, reliable performance of your bike and to minimize damage to other components, sprocket replacement should happen long before then.
How do I know if my sprocket is bad?

How much does it cost to change a front sprocket on a motorcycle?
If your chain is relatively new, it will not hurt it to change only one sprocket. Considering that a front sprocket is typically only $20-30, I recommend changing it as an inexpensive way to test a new gearing ratio, before you take the plunge and spend the money to change both sprockets and your chain.

Do you need to change the sprocket on a chain saw?
This is a judgment call, and there are differing opinions. Generally, it is advisable to change sprocket and chain components as a set, because they wear as a set; if you do this, we recommend a high-strength aftermarket chain from a top brand like EK, RK, and DID. However, in many cases, it won’t hurt to change one sprocket (usually the front.)
