Adjustable wrenches
Wrench set
The 2007 Kawasaki Vulcan 900 uses a Kevlar belt for the final drive instead of the traditional chain. This provides a quieter ride with less chain vibration. Fortunately for those used to the traditional chain drive, the process for adjusting the belt drive is almost the same. Lifting the motorcycle is not required to adjust the belt drive.
Step 1
Place an adjustable wrench on each axle nut located on either side of the rear tire. Loosen each axle nut just enough to allow the axle to slide backwards in the swing arm. A quarter turn is usually sufficient.
Step 2
Locate the adjustment bolt on the left side of the Vulcan. It is just to the left of the axle nut and runs parallel with the frame. Turn the nut a quarter turn clockwise using a wrench.
Step 3
Locate the adjustment bolt on the right side of the Vulcan. It is just to the right of the axle nut and runs parallel with the frame. Turn the nut a quarter turn clockwise using a wrench.
Step 4
Tighten both axle nuts using the adjustable wrenches.
Step 5
Press down on the top center of the Kevlar belt between the sprocket and where the belt goes into the transmission housing. Your goal is approximately ½-inch flex when you lightly press on the belt with your finger.
Step 6
Repeat these steps until you achieve the correct amount of flex in the belt if your first adjustment did not meet the required amount of belt flex.
