Many owners have either trimmed or completely eliminated the stock black plastic rear fender to improve the rear end appearance of the bike. This page describes the rear fender elimination process, the fabrication and installation of a custom undertail piece, the modification of the stock license plate bracket, and installation of Lockhart-Phillips short-stalk, clear-lens rear turn signals.
The credit for the design of this project goes to Peter K., screen name Jarzyna, from the Owner's Association. The original diagrams for the metal parts were provided by him.
This is an inexpensive project parts wise but is highly labor intensive. An assortment of proper tools is critical. A good bench vise is paramount as is a Dremel tool, power drill, and steel files. More useful tools are listed in the descriptions below.
The cost of materials for this project is about:
Lockhart-Phillips Turn Signals, Part Number 122-9816 - $22.00.
Sheet Aluminum comes in a size 8" x 18" x .025"- $6.00
L-shape aluminum bar stock, 1 1/4" x 1 1/4" x .125" x 1 foot - $3.00
Miscellaneous - Spray Paint, Primer, Silicone Sealant, Blue Loctite, Screws, Nuts, Washers - ?
The labor time required depends on how quickly you feel comfortable proceeding. I went very slowly.
Replacement bulbs for the Lockhart-Phillips turn signals are part number 122-9605, amber bulb, single filament. The price is about $2.50.
The procedure is to:
1. Remove Stock Undertail:
Remove Seat and loose items such as tool kit, etc. When proceeding, many different sizes and types of bolts
will be removed. The photos below will help identify which ones comes from where but you may want to make
separate notes to assist you when reassembling.
Remove Left and Right Side Covers
Remove Seat Cowl Handles
Remove Seat Cowl
Remove Battery
Remove Undertail Attachment Bolts under Side Covers
Remove Rear and Two Rear Side Attachment Bolts
Remove Center Hold Down Phillips Screw
Remove Rear Brake Fluid Cylinder Attachment Phillips Screw
Detach Fan Motor and Starting Circuit Cutoff Relays Under Left Side Cover
Detach Yellow Box if Installed
Detach Fuse Box
Unscrew Ignitor Unit
Unscrew Tip Over Sensor
Detach Flasher Relay
Detach Starter Relay
Unhook Tail Light and Turn Signal Connectors
Flex Undertail Around Seat Lock Assembly
Pull Undertail Backwards Watching Cables and Remove

2. Trim the Stock Undertail:
Work slowly, take your time, and expect a huge mess. Remember, if you remove too much plastic you have ruined the undertail.
Stop frequently, check your work often on both sides of the undertail. Know what you are cutting and how much you are
cutting before you cut it. Ok, here it comes: "Measure Twice, Cut Once."
3. Fabricate the License Plate and Turn Signal Brackets:
The license brackets are made from 1 1/4" x 1 1/4" x .125" L-Bracket aluminum bar stock. A one foot length is enough
for all the brackets. The plans show slightly different thickness for the aluminum. I used .125" thick stock for all
three pieces. The plan shown below is only a guide.
When then brackets are finished, prior to painting, it is a good idea to temporarily attach the turn signal brackets
and the turn signals onto the license plate bracket using all screws, nuts, and washers to verify sufficient clearances and
hole sizes for position adjustment. See the section below on attaching the brackets and turn signals for how to do this.
Paint the pieces, first with a zinc primer, then satin black
4. Fabricate the Undertail Plate:
The piece made must fit according to the manner in which the
undertail was trimmed. Hence actual measurements and sizes will vary. Start by making all sizes a bit larger than necessary
then trim down to fit. As with the undertail trimming, material can always be removed it can never be added.
The undertail piece is made from .025" sheet aluminum. The aluminum is easily cut with the straight edge cutter,
trimmed with a hacksaw blade, and filed to shape. Use primer on the aluminum before the satin black paint.
This is a more detailed version of the initial guide I used. Afterwards, the actual plate was hand worked and matched to
the trimmed undertail to verify the fit.
5. Trim the Ends of the Stock License Bracket:
Remove the stock license plate bracket using a 10 mm hex wrench.
The stock license bracket with its rounded edges is too wide and protrudes beyond the ends of the
license plate. This would also obscure the inside portion of the turn signals. The easy solution is simply
to trim the ends. You will probably damage the finish on the bracket with the cutting so you may have to paint it. I
used a primer coat first then satin black.
6. Install Undertail Plate, Brackets, and Turn Signals:
Do the following procedures in the order shown:
Drill Plate Mounting Holes
Reinstall Stock Tailight Attachment Bracket
Attach License Plate Bracket to Undertail Plate
Mount Plate in Place
Paint Metal Screw Tops Black
Attach Turn Signal Brackets
Attach Turn Signals
Attach License Plate Bracket
7. Reinstall Modified Undertail and Connect Turn Signals:
Reinstalling the undertail is much easier than removing it. Just reverse the removal procedure.
Then connect the new turn signals.
Lastly, mount the license plate to the modified bracket.

Update:
I upgraded the Lockhart-Phillips short stalks with LED units from Rizoma. These are really sharp looking and every bit
as bright, if not brighter, than the bulbs. The Tridon EP-37 constant rate flasher
works well with these and my front LED's to keep the flashing rate correct. Contact Mike Pijanka
at pjsparts.com for availability and pricing if
interested in these little jewels.
