The Victory motorcycles with the 5-speed gearbox have a short shift. The first gear is almost not usable and high gear is not high enough. This two-tooth larger pulley makes your bike more user-friendly.

Victory 32 Tooth Overdrive Pulley. Fits all 03-05 Victor motorcycles and 99-01 Victory with upgraded transmission. This pulley reduces RPM by 7% and uses All Factory Parts. I decided to install this pulley on my 2004 Victory Kingpin and write up step-by-step installation instructions along with pictures on the installation. Below are my work instructions for the installation.

I did other maintenance and decided to ride a jacket.
You do not need to remove the wheel. In fact, you want to leave it to help remove the sprocket.
I removed the relief part of the exhaust gas first to ease the exhaust gas.
Remove the belt guard.
Remove the floor board on the right side so you can pull off the exhaust.

Before removing the exhaust gases.
Observe the condition of the exhaust flange nuts.
The exhaust flange bolts can be rusted. Spray with WD-40 and leave overnight to loosen them.
After removing these flange nuts, remove the exhaust gas.

Here is Kingpin with everything removed.
Exhaust gas, belt protection, driver side on right side.
The wheel does not need to be removed. In fact, it should be installed to help remove the sprocket.

Removed exhaust system. The slip on containers is here somewhere.

When degassing, remove the chain wheel belt pulley cover.

With the chain body you now cover the gear.
Here I have the belt loose. You want it neat and wheeled, as this will be used as a resistor when you remove the sprocket nut.

Another shot on the right side of Kingpin was completely removed.

Remove the chain coupling screws and the locking plate.

Remove the sprocket lock plate.

The sprocket nut takes 48 mm socket.
The nut has Loctited at the factory.
You can either use an impulse key to delete. Heat it up to loosen Loctite.
Here I use my heat gun. It took about 10-15 minutes to just hold the rear brake pedal and remove the nut.
Allow the sprocket to cool.
It slides straight away.
Then, if necessary, clean the left over Loctite gunk from the gearwire.

Once you have removed the nut, you must loosen the belt to remove it and install the new pulse.
The chain wheel slides straight away after you loosen the belt.

Here, the single drive shaft is waiting for the new drive wheel.
Stay focused on more because this is all I've got. I now need to order the new chain wheel.

The bike should be completely lower right side, bags, passenger floor, guide plates and controls, side cover for pulley, belt cover (upper and lower) and belt removed. The worse part of the job was the exhaust system, be careful with them. Here is a picture of the bike ready to start putting it back together. Now clean everything you have removed and clean the engine and all areas exposed.

Grind the tab that holds the speed sensor. Release 3/8 to 1/4 "from the bottom of the tab but not all the way to the engine block.

Continue to try the OD belt pulley until it goes all the way without pressing the tab. The side panel cover must also be ground down to allow release of the drive belt. It will rub on the bolt's sleeves.

Now install the speed sensor using washers with a thickness of about 3/8 to 1/4 "place them over the screw hole and then place the speed sensor on top of the washers, hold in the bolt and tighten.

Check the wheel alignment and belt tension. With the bike raised on a lift, rotate the rear wheel until you find a narrow seat belt - halfway between the front wheel and rear pulleys. You should have about 9mm flex with 10lb force on the bottom. The marks on the swing arm are useless. When the voltage is set, rotate the wheel and check the belt adjustment by looking at the belt track on the front and rear pulleys. The drive belt must not rub on the back of the rear wheel.

Finally, reinstall the exhaust system. Be careful not to scratch the pipes when operating them in position.

Please do not include the Victory overdrive pulley manufacturer's installation instructions with their product. Hopefully, these instructions will help you through the installation. I have found very good help from the Kingpin Cruiser website website. This installation requires some good wrenching skills, but if a service tech can do that, you will surely be able to do it and do a much better job.
