The Victory motorcycles with the 5-speed transmission has gearing that is a little short. First gear is almost not usable and high gear is not high enough. This two teeth larger pulley makes your bike more user friendly.

The Victory 32 Tooth Overdrive Pulley. Fits All 03-05 Victor motorcycles and 99-01 Victory’s with Upgraded Transmission. This pulley will decrease RPM by 7% and uses All Factory Parts cordless impact wrench review¬† . I decided to install this pulley on my 2004 Victory Kingpin and write up step-by-step installation instructions along with photos of the install. Below are my working notes for doing the installation.

I was doing other maintenance and decided to put the bike on a jack.
You do not need to remove the wheel. In fact you want to leave it on to help in the removal of the sprocket.
I removed the slip-on part of the exhaust first to lighten the exhaust.
Remove the belt guard.
Remove the right-side drive floor board so you can pull the exhaust off.

Prior to removing the exhaust.
Note the condition of the exhaust flange nuts.
The exhaust flange bolts may be rusted. Spray with WD-40 and let stand overnight to loosen them up.
After you get these flange nuts off, remove the exhaust.

Here is the Kingpin with everything removed.
Exhaust, belt cover, driver right-side floor board.
Not the wheel does not have to be removed. In fact it should be installed to help in the removal of the sprocket.

Removed exhaust. The slip on canisters are around here somewhere.

With the exhaust off, remove the sprocket pulley cover.

With the Sprocket cover off you now see the Sprocket.
Here I have the belt loose. You want it snug and the wheel on since this will be used as your resistance when removing the sprocket nut.

Another shot of the right side of the Kingpin completely stripped.

Remove the sprocket lock plate screws and lock plate.

Remove the sprocket lock plate.

The sprocket nut takes a 48mm socket.
The nut has been Loctited at the factory.
You can use either an Impact Wrench to remove. Heat it up to loosen the Loctite.
Here I am using my heat gun. It took about 10-15 minutes to where I could simply hold the rear brake pedal and remove the nut.
Let the sprocket cool down.
It will slide right off.
Next, clean off any left over Loctite gunk off of the sprocket rod threads.

After removing the nut you will have to loosen the belt to remove,and install the new pully.
The sprocket will slide right off after you loosen the belt.

Here is the lonely drive shaft in wait of it’s new drive sprocket.
Stay tuned for more since this is all the further I have gotten. I need to now order the new sprocket.

Bike should be all the way tore down on the right side, Bags, Passenger Floor Board,Driver Floor Board and Controls,Side Cover for the Pulley,Belt Covers(top & bottom) and Belt removed. The worse part of the job was the Exhaust System, be careful with them. Here’s 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 that are exposed.

Grind the Tab that holds the Speed Sensor. Grind about 3/8’s to 1/4″ off the bottom of the tab but not all the way to the side of the engine block.

Keep trying the OD Pulley until it goes all the way on without hitting the Tab. The side pulley Cover will also need to be ground down to allow clearance for the drive belt. It will rub on the bolt sleeves.

Now install the Speed Sensor using washers of a thickness of about 3/8’s to 1/4″ put them over the screw hole and then put the Speed Sensor on top of the washers, stick the bolt in and tighten down.

Check wheel alignment and belt tension. With the bike elevated on a lift rotate the rear wheel until you find tight spot in the belt — halfway between the front and rear pulleys. You should have about 9mm of flex with 10lb of force on the bottom. The marks on the swing arm are useless. After tension is set rotate the wheel and check belt alignment by watching the belt track on the front and rear pulleys. The drive belt should not rub on the sides of the rear sprocket.

Finally reinstall the exhaust system. Be careful not to scratch the pipes as you maneuver them into position.
