4. Using a T27 Torx® drive head, loosen upper screw securing handlebar clamp to master cylinder housing. Remove lower clamp screw with flat washer.
NOTE
If possible, leave friction shoe in place. The friction shoe is a loose fit and may fall out or become dislodged if lower switch housing is turned upside down or shaken.
5. See Figure 9. Remove brass ferrules from notches on inboard side of throttle control grip. Remove ferrules from cable end fittings.
6. Pull crimped inserts at end of throttle and idle control cable housings from lower switch housing. For best results, use a rocking motion while pulling. Remove cables with retaining rings from switch housing. Place a drop of light oil on the retaining ring, if necessary, to help in removal.
NOTE
At this point, if you have (or are installing) different handlebars, measure the change in distance that will be required from the end of the cable housing to the throttle grip. Compare this additional required length to the cables provided in your kit.
If the cables are more than two inches longer or more than one inch shorter than the above measured distance, see your Harley-Davidson dealer for the correct cable length.

Throttle/Idle Cable Installation
1. See Figure 9. Apply graphite lightly to the throttle grip inside the switch housing and on throttle end of handlebar.
NOTE
The throttle control cable has a larger diameter retaining ring crimped to the cable end than does the idle control cable.
For assembly, place a drop of light oil on the retaining rings of the crimped inserts.
2. See Figure 10. Push throttle cable housing and retaining ring into switch housing larger hole, located in front of tension adjuster screw.
3. Push idle cable housing and retaining ring into switch housing smaller hole, located behind tension adjuster screw.
4. Push throttle and idle control cable housings into lower switch housing until each snaps into place.
NOTE
If the friction shoe has fallen out or become dislodged, install the shoe with the concave side facing upward and orient so the pin hole is over the point of the adjuster screw.
5. Push throttle control grip over the end of right handlebar until it bottoms against the closed end. Rotate grip until the ferrule notches are at the top. To prevent binding, pull grip back about 1/8 in. (3.2 mm).

6. See Figure 9. Position lower switch housing beneath throttle control grip. Install two brass ferrules (56508-76) from kit onto cables, seating the ferrules in their respective notches on throttle control grip. The cables must be captured in the grooves molded into the grip.
7. Position upper switch housing over the handlebar and lower switch housing. Route wire harness conduit through recessed area at bottom of handlebar.
8. Loosely fasten upper and lower switch housing screws.
9. Position brake lever/master cylinder assembly inboard of switch housing assembly, engaging tab on lower switch housing in groove at top of brake lever bracket.
10. Align holes in the handlebar clamp with those in master cylinder housing and loosely fasten lower screw and flat washer. Position for rider comfort. Beginning with top screw, tighten screws to 60-80 in-lbs (6.8-9.0 Nm) using a T27 Torx® drive head.
11. Torque lower and upper switch housing screws to 35-45 in-lbs (4-5 Nm).
NOTE
Always tighten lower switch housing screw first so that any gap between upper and lower housings is at the front of the switch assembly.
12. Adjust throttle and idle cables according to the Service Manual instructions.
WARNING
Be sure that steering is smooth and free without interference. Interference with steering could result in loss of vehicle control and death or serious injury. (00371a)
13. Remove cardboard insert between brake lever and lever bracket.
  • Cables should not catch on headlamp hardware or pass in front of headlamp.
  • Cables should not catch on turn signal mounting hardware or turn signals.
  • Cables should not catch on fuel cap or fuel gauge.
  • Cables should not catch on speedometer or tachometer.
  • Be sure cables are not pinched between the frame and/or forks.
  • Be sure clutch cables do not pull tight when handlebars are turned fully to the left or right fork stops.
WARNING
Connect positive (+) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00068a)
  1. Connect the battery cable, positive (+) cable first.
Assemble Clamps to Windshield
1. See Figure 11. Remove windshield sub-assembly from packaging and place face down on a clean, soft surface with mount brackets facing upward.
2. See Figure 13 or Figure 14. Remove both clamp and hardware kits from packaging, and separate similar parts in preparation for assembly.
3. See Figure 12. Assemble clamp assemblies and hardware stacks.
WARNING
The cupped side of the Belleville (cone) washers must face each other and sandwich the windshield mount brackets at each mount point. Failure to orient washers correctly can reduce windshield's ability to break away in a collision, which could result in death or serious injury. (00422b)
4. One clamp at a time, with clamp facing upward and inboard of windshield bracket (2), tighten shoulder bolts (1) enough to hold clamp orientation to windshield during mounting of windshield to bike. The bolts will be fully tightened later.

Install Windshield
NOTE
Keep front wheel straight to prevent brackets from scratching fuel tank.
1. Make sure all four clamps are in the "open" position, then bring windshield (with clamp side away from you) to front of bike.
NOTE
The Lexan® windshield is fairly flexible and can be bent to spread the clamps away from the headlamp to ease installation to the bike. Take care not to scratch the headlamp housing with the clamps while positioning the windshield to the fork sliders.
2. Straddle front fender and check to ensure that throttle cables are positioned between the clamp pair on your left (as viewed facing the bike, holding the windshield), and will not be pinched by the clamps. Center windshield around the headlamp and seat clamps onto fork sliders.
WARNING
Pinched throttle cables can restrict throttle response, which could result in loss of control and death or serious injury. (00423b)
3. Starting at bottom (either side) with shoulder bolts loosely threaded, close each clamp, noting that clamps self-align to fork sliders and to each other.
NOTE
Do not tighten shoulder bolts beyond the recommended torque. Over-torquing may cause the clamp to twist on the fork slider, yielding the clamp jaw can occur.
4. Make sure that shoulder portion of shoulder bolts are fully seated in each windshield bracket location. Torque each shoulder bolt to 60 in-lbs (6.7 Nm).
NOTE
If interference occurs, adjust windshield as needed until proper clearance is obtained. Have experienced Harley-Davidson service personnel correct any problems before riding with this accessory installed.
Remove and Store Windshield
To remove windshield, open four clamps, in any sequence, and reverse installation procedures found in Steps 3 and 4 of Install Windshield subtopic. Take care to not scratch headlamp housing or fuel tank as noted during installation.
When storing windshield, place in a location where windshield clamps will receive the greatest protection. Keep from locations where the windshield may be bumped or dropped. Do not stack anything on top of assembly.
Prior to re-installation after any storage period, inspect clamps and hardware for fastener preload and cleanliness. Each clamp should have a pair of rubber gaskets in the clamp saddle that mates to the fork slider, and should cycle open and closed freely.
CARE AND CLEANING
NOTE
Sunlight reflections off inside surface of windshield can cause extreme heat build-up on motorcycle instruments. Exercise care in parking. Park facing the sun, place an opaque object over instruments, or adjust windshield to avoid reflections.
NOTICE
Harley-Davidson windshields are made of Lexan. Lexan is a more durable and distortion-resistant material than other types of motorcycle windshield material, but still requires attention and care to maintain. Failure to maintain Lexan properly can result in damage to the windshield. (00230b)
  • Do not clean Lexan® polycarbonate in hot sun or high temperature. Powdered, abrasive, or alkaline cleanser will damage windshield. Never scrape windshield with a razor blade or other sharp instruments because permanent damage will result.
NOTICE
Use only Harley-Davidson recommended products on Harley-Davidson windshields. Do not use harsh chemicals or rain sheeting products, which can cause windshield surface damage, such as dulling or hazing. (00231c)
NOTICE
Do not use benzine, paint thinner, gasoline or any other type of harsh cleaner on the windshield. Doing so will damage the windshield surface. (00232c)
  • Do not use benzine, paint thinner, gasoline, lubricants (including Armorall®), or other cleaning agents on rubber bushings. They will damage bushing surfaces.
NOTE
Covering the windshield with a clean, wet cloth for about 15 minutes before washing will make dried bug removal easier.
