How does rear sprocket affect final drive ratio?
Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV. Short answers never tell the whole story, of course.
Why does my car vibrate at 1000 rpm?
Between 1000 & 2000 rpm Shaking or vibration may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
Can you change the sprocket on a street bike?
Changing gearing on street bikes can be more complicated than with a motocross bike or ATV. If you change the front sprocket, your street bike’s speedometer will very likely read incorrectly. You’ll need to correct that. Also, changing sprockets on a track-riding sportbike can change the effective wheelbase of the bike enough to affect handling.
What kind of sprocket should I use for racing?
For competition-quality sprockets, JT uses 7075 T6 aluminum. Its high strength-to-density ratio makes it ideal for racing applications. JT’s countershaft sprockets are made of full heat-treated chromoly SCM415 steel. Many other manufacturers simply “surface harden” their countershaft sprockets.
Why does my Harley Davidson have a vibration problem?
I have a vibration problem that occurs when I release the throttle to slow down or come to a stop. At a certain rpm it vibrates so bad it sounds as if the fairing and tourpak are going to fall off. The vibration has already ruined the front motor mount which I replaced.

How can I tell if my Harley Davidson sprocket is loose?
Open up the inspection cover and pry the sprocket in both directions while watching the rotor , they should both move together . If the sprocket moves in either direction but the rotor doesn’t then the nut is loose . I’d start by looking at the primary chain tension.
