Victory motorcycles with a 5-speed transmission have slightly short gears. The first gear can hardly be used and the high gear is not high enough. This larger two-tooth pulley makes your bike easier to use.

The 32 tooth Victory overdrive pulley. Fits all 03-05 Victor and 99-01 Victory motorcycles with upgraded transmission. This pulley will decrease RPM by 7% and uses all factory parts. I decided to install this pulley on my 2004 Victory Kingpin and wrote the step by step installation instructions along with photos of the installation. Below are my working notes to do the installation.

I was doing other maintenance and decided to put the bike on a jack.
No need to remove the wheel. In fact, you want to leave it on to help remove the sprocket.
I first removed the slip-on part of the exhaust to lighten the exhaust.
Remove the belt guard.
Remove the right side transmission floor board so you can get the exhaust out.

before removing the exhaust.
Note the condition of the exhaust flange nuts.
The exhaust flange bolts may be rusted. Spray with WD-40 and let it sit overnight to loosen them up.
After removing these flange nuts, remove the exhaust.

Here is the Kingpin with everything removed.
Exhaust, belt cover, right driver’s side floorboard.
It is not necessary to remove the wheel. Indeed, it must be installed to assist in the removal of the sprocket.

Exhaust removed. The slippery boats are around here somewhere.

With the exhaust off, remove the pinion pulley cover.

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

Another shot of the Kingpin’s right side completely stripped down.

Remove the sprocket lock plate bolts and lock plate.

Remove the sprocket lock plate.

The pinion nut has a 48mm socket.
The nut has been located at the factory.
You can use an impact wrench to remove. Heat it to loosen the Loctite.
Here I am using my heat gun. It took me about 10-15 minutes until I was able to just hold the rear brake pedal and remove the nut.
Let the sprocket cool down.
It will slide right off.
Next, clean any remaining Loctite from the threads of the sprocket rod.

After removing the nut, you will need to loosen the belt to remove it and install the new pulley.
The sprocket will slip immediately after the belt is loosened.

Here is the lone driveshaft awaiting its new drive sprocket.
Stay tuned for more as this is as far as I’ve come. Now I need to order the new sprocket.

The bike must be completely disassembled from the right side, bags removed, passenger floorboard, driver’s floorboard and controls, pulley side cover, belt covers (upper and lower ) and the strap. The worst part of the job was the exhaust system, watch out for those. Here’s a picture of the bike ready to start putting it together. Now clean everything that you have removed and clean the engine and all the areas that are exposed.

Grind the Tab that holds the Speed ​​Sensor. Grind 3/8 to 1/4″ from the bottom of the lug, but not to the side of the engine block.

Keep testing the pulley OD until it advances completely without touching the lug. The side pulley cover will also need to be refaced to make room for the drive belt. It will rub the sleeves of the bolts.

Now install the speed sensor using washers about 3/8 to 1/4″ thick, place them over the screw hole and then place the speed sensor on top of the washers, insert the bolt and tighten.

Check wheel alignment and belt tension. With the bike raised on a lift, turn the rear wheel until you find a tight spot on the belt, midway between the front and rear pulleys. You should have about 9mm of flex with 10lbs of force on the bottom. The marks on the swingarm are useless. After adjusting the tension, turn the wheel and check the alignment of the belt by noting the path of the belt on the front and rear pulleys. The drive belt must not rub against the sides of the rear sprocket.

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

Please note that the manufacturer of the Victory overdrive pulley does not include installation instructions with their product. We hope that these instructions will help you during the installation. I have found some great help on the Kingpin Cruisers site at http://www.KingpinCruisers.net. This installation requires some good wrench skills, but if a service technician can do it, they will surely be able to do it and do a much better job.
