Installing the Turbotec Drive Pinion Pulley for Victory Motorcycles

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 Victory 32 tooth overdrive pulley. Fits all Victor 03-05 and Victory 99-01 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 write 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.
It is not necessary to remove the wheel. In fact, you should leave it on to help remove the sprocket.
I first removed the sliding part of the exhaust to lighten the exhaust.
Remove the belt guard.
Remove the floor board from the right side unit so you can remove the exhaust.

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 sit overnight to loosen.
After removing these flange nuts, remove the exhaust.

Here’s the Kingpin with everything removed.
Exhaust, belt cover, floor on right driver’s side.
It is not necessary to remove the wheel. In fact, it should be installed to aid in sprocket removal.

Escape removed. The slide boats are around here somewhere.

With the exhaust off, remove the sprocket pulley cover.

With the Sprocket cover removed, you will now see the Sprocket.
Here is my belt loose. You want it to be snug and the wheel on, as this will be used as resistance when removing the pinion nut.

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

Remove the sprocket lock plate screws and lock plate.

Remove the sprocket lock plate.

The sprocket nut has a 48mm socket.
The nut has been fitted 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 10-15 minutes until I was able to just hold the rear brake pedal and remove the nut.
Let the pinion cool down.
It will slide off immediately.
Then clean any Loctite dirt from the sprocket rod threads.

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

Here’s the lone driveshaft waiting for its new drive pinion.
Stay tuned for more, as this is the furthest I’ve come. Now I need to order the new sprocket.

The bicycle must be completely ripped from the right side, bags, passenger floor panel, driver’s floor panel and controls, pulley side cover, belt covers (upper and lower) and the belt must be removed. The worst part of the job was the exhaust system, be careful with them. Here’s a photo of the bike ready to start riding. Now clean up whatever you have removed and clean the engine and all exposed areas.

Grind the tab that holds the speed sensor. Grind about 3/8 to 1/4 “from the bottom of the lug, but not all the way to the side of the engine block.

Keep testing the OD pulley until it is fully advanced without touching the tab. The side pulley cover will also need to be ground to allow clearance for the drive belt. It will rub the screw sleeves.

Now install the speed sensor with washers about 3/8 to 1/4 “thick, put them over the screw hole and then put the speed sensor on top of the washers, fit 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 narrow spot on the belt, midway between the front and rear pulleys. It should have approximately 9mm of flex with 10lbs of force at the bottom. The marks on the swing arm are useless. After adjusting the tension, turn the wheel and check the belt alignment by observing the belt path 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 position them.

Please not the manufacturer of the Victory Overdrive Pulley does not include installation instructions with their product. Hopefully these instructions will help you through the installation. I found very good help on the Kingpin Cruisers site at http://www.KingpinCruisers.net. This installation requires some ripping skills, but if a service technician can do it, they will surely be able to do it and do a much better job.
