Race Tech recommends using heavier 15-weight fork oil with its gold emulator kits. We chose to use Bel-Ray 15-weight.

Using a Ratio Rite, the forks were filled to the required amounts as per the Race Tech instructions. It recommends 160mm of fork fluid for this particular model year.

We replace the upper washer from the Race Tech kit with the solid washer that is included with the Speed Merchant preload adjuster kit.

The Speed Merchant adjuster sits on the solid washer so it can adjust the fork spring tension via its adjuster post

Using some strength, install the Speed Merchant preload adjusters. This can be a dangerous task if the adjuster pops free and hits you in the face, so wear eye protection!

Once you have the preload adjusters installed, take a wrench and snug the adjuster until it’s secure. Be careful not to scratch the adjuster when snugging. Once the fork is installed in the triple tree, you can do a final torque to assure it won’t come loose.

Once you’re done, your forks should look similar to these. Once installed, you will need to test ride and see how you like the way it feels. You can adjust the Race Tech gold emulators to your riding style. It may take a few times to get it dialed in the way you want, but once it is you’ll be a very happy rider.

The stock production 39mm front ends on Dynas, FXRs, and Sportys need a little help if you want to get some better performance out of them. Hell, even changing the weight of the oil used internally can help with getting them to react better on the road. Luckily for us (and you) there are a ton of performance goodies on the market, and taking advantage of some such items will make your Harley ride much better and look good while doing so. We are building a stiffer and better 39mm front end with the help of a set of Chassis Design Company triple trees, Gold Valve emulators and a spring kit from Race Tech, a set of The Speed Merchant’s preload adjusters, and some oil from Bel-Ray. We will be putting it all together with the right tools for the job thanks to Jims USA and its line of specialty tools. Here’s how we did it.
