How to Clean the Enricher on Your Sportster
Harley-Davidson calls them enrichers. Everybody else calls them chokes. When you pull out the knob under the left side of your gas tank you increase, or fatten, the percentage of gasoline in your carburetors gas-fuel mix. Pushing the knob in leans the fuel mixture. The knob is attached to a cable that attaches to an enricher valve inside the body of your carburetor. Maintaining and lubricating this cable is a standard procedure you should perform on your Sportster every 2,500 miles or every two months.
Instructions
- 1
Put the motorcycle in first gear. Turn off the engine, lean the motorcycle on the jiffy stand and let the engine go cold.
2Fully extend the enricher knob. Unhook the enricher cable from the clip under the gas tank near the horn. Wipe the exposed cable, knob and clip with a rag.
3Spray cable lubricant on the enricher cable and inside the enricher cable guide tube under the gas tank. Wipe up drips with the rag.
4Refasten the enricher cable to the clip near the horn. Pull and push the enricher knob in and out to distribute the lubricant along the full length of the enricher cable.

How to Install Sportster Forward Controls
Harley motorcycles are usually designed to let you ride with your hands up and feet stretched out in front. One exception is the Sportster, which was born as a dirt track bike, and still usually locates the foot pedals, rear brake and shift lever right under the riders knees. However, most Harley riders think the feet forward, lay back position is a more comfortable position to ride in for long distances. The usual way to achieve that lay back position on a Sportster is with a forward control kit. Numerous vendors sell these and installation is straightforward.

How to Disassemble a Sportster Primary
The primary drive on a Harley Davidson Sportster is concealed inside a metal case to prevent any part of your clothing or body from becoming trapped in the rapidly spinning belt while youre riding the bike. If you need to adjust the primary chain, you must remove the cover. There are some discreet little bolts that hold the whole assembly together, which can be difficult to find if you dont know where to look.

Run the engine for three to five minutes until the temperature starts to rise. This will thin the oil in the primary, allowing it to drain more readily. Place the bike on its side stand and put the container under the primary. Loosen and remove the drain plug from the underside of the primary cover, and drain the oil into the container.
2Use an Allen wrench to loosen the bolts around the circular Derby cover, which is mounted on the primary cover. The clutchs spring mechanism has to be removed before the rest of primary cover can come off. The mechanism is behind the Derby cover. Remove the uppermost locking nut, which will release the spring underneath. Slide the spring out, which will reveal another locking nut beneath it. Loosen and remove this nut, too. Store both nuts and the spring in a safe place.
3Work around the outer edge of the primary cover, loosening and removing all of the Allen bolts on the outer perimeter of the cover. Once youve removed the last one, the primary cover should lift off.

How to Add an Oil Cooler to a Sportster
All Harley engines, except the engines on V-Rods, are air-cooled, transversely mounted, two cylinder engines. The 45 degree, V-mounting on both Sportster and Big Twin engines reduces cool air flow around the cylinders. Mounting the hot exhaust near the cylinders also increases engine temperature. All of these identically designed Harley engines have cooling fins on the cylinders to help them radiate heat. An oil cooler mounted on the front also carries heat away from the engine in two ways. An oil cooler will increase the oil capacity of a Sportster from three to four quarts and more oil carries more heat. A cooler also increases the radiating surface for that engine oil.

Unfasten the drain tube from the Sportster oil tank. Loosen the hose clamp with a screwdriver.
2Remove the drain plug and drain the engine oil into a pan. Unscrew the oil filter on the front of the Sportster with an oil filter wrench.
3Drain the oil in the filter into a pan. Discard the filter. Clean the front of the bike with rags.
4Disconnect the oil pump and crankcase feed hoses with an open end wrench. Apply gasket and thread sealer to the oil line fittings included with your oil cooler kit.
5Replace the old oil pump and crankcase lines with the new lines. Tighten the new fittings to 60 inch pounds with a torque wrench and an open end socket.
6Coat the threads of the oil line fitting included in your oil cooler kit with gasket and thread sealer. Attach the fittings to the openings in the oil pump and crankcase. Tighten the fittings to not more than 65 inch pounds of torque with a torque wrench.
7Unhook the wiring harness extension and clutch cable from the clips on left front of the bike. Remove the clips.
8Replace the clips with chrome oil cooler clamps from your oil cooler kit.
9Attach the oil cooler to the chrome clamps with the Allen bolts and nuts that came with your oil cooler. Plug the oil feed and oil return hoses on the oil cooler fittings.
10Secure the feed and return hoses with the hose clamps included with your oil cooler. Tighten the hose clamps with a screwdriver.
11Point the front of the cooler forward. Tighten the clamp screws to 30 inch pounds with a torque wrench and an Allen socket.
12Reattach the wiring harness extension and clutch cable to the oil cooler clamps. Tighten all hose fittings 22 foot-pounds of torque with a torque wrench.
13Wipe clean oil on the rubber gasket of a new oil filter. Spin the filter onto the filter stud and hand tighten.
14Add three quarts of oil to the oil tank. Run the motorcycle in neutral for five minutes.
15Check for oil leaks while the engine is running. Ensure the oil cooler gets warm. If the oil cooler stays cold a hose or fitting must be blocked.
16Turn off the motorcycle and add a fourth quart of oil to the oil tank. Turn the engine over and read the dipstick.
17Add oil if the dipstick reads below full. Retighten all fittings when the engine is cold.
