Harley FLHS

I bought a 1990 FLHS Harley Davidson in 1992. It had less than 10,000 km. It was pretty much stock when I got it, with these accessories:

Chrome wind deflectors HD 58121-85A
Oil Tank Cover Chrome Trim Rail HD 66050-91
Electra Glide Sport Saddlebag Guard Kit HD 30839-83
Headlight and Spotlight Brim - Custom Chrome

Here's a list of the mods and repairs I've done to it since:

Air Filter replaced with K&N HD-1390
Stock CV Keihin carburetor modified per the instructions on Nightrider
Carb Needle jet replaced with #27094-88, idle jet 45, main 185
Spark Plugs replaced with Bosch Platinum-4 "4488"
Broken Shifter Spring: Transmission shifter shaft and spring replaced. This was done from the tranny side without disturbing the primary.
Rattling gearshifts: After looking at a new Road King, I did the same and cut a 3/4" ID rubber hose, 3/4" wide and slipped it over the metal collar between the gearshifts and the primary case to dampen the rattling.
Leaking cylinder base gaskets: Replaced original paper gaskets with James

Oil drips out bottom of aircleaner: Vented crankcase overboard instead of into aircleaner. Ran a tube from the vent under the cam nose over the top of the frame under the seat. Installed an inline filter there and then continued the tube down to dump in front of the rear wheel with the other breathers. No more oil drips.

Goofy ignition: Re-wired ignition switch so lights only came on when switched to "LIGHTS".
Lighting improvement: Spotlights re-wired to work on both hi/lo beam (Harley wires them to work only on low). Headlight replaced with 100w/55 high/low. No relay, no problems.
Voltage regulator replaced: cruising along and noticed the turn signals no longer worked. After a while the engine stopped. A "no charge" idiot light would be nice, or maybe a small voltmeter....
Tires: running an Avon Roadrunner AM-20 on the front; sand had a AM-21 on the rear, which was changed to a Bridgestone Spitfire R11 this year.
Battery: Yuasa YTX24HL-BS (sealed, glass mat, 350 cranking amps!)

Accessories Bought:

Custom Dresser Solo Saddle with leather skirt HD 52156-91 . Lets you stretch out a little and lowers the seat a little. More comfortable but makes it more selfish (no passengers)
Rear licence plate bracket HD 4734983A . Modified by angling it forward to match the saddlebags angle instead of straight vertical.
FLHS Chrome headlight nacelle HD 67680-91 . That "Road King" look!

FLHS Chrome windshield mount HD 58069-93
