Decel wobble service bulletin
Can i please have a link for the service bulletin about decel wobble in 09 and newer touring bikes...i would like to take this in with me so the dealer doesn't think i am crazy when i tell them i am getting a wobble at 40 and below....i looked here already...

have not heard of any decel wobble on '09 and newer touring bikes. the only way you would know if it was wobbling would be if you let go of the handle bars...and that is not likely as you would be braking, down shifting, and maintaining lane position. sounds like your tire is out of balance or cupping--maybe have them check steering head for tightness and fall away.

The M1246 bulliten refers to the adjustment of the steering head bearings. Harley issued a service bulletin (M-1246)
Purpose
A revised procedure has been identified for adjusting steering
head bearings on 2009 Touring model motorcycles.
Please note this change is unique to 2009 models only and
does not affect earlier model year vehicles.
Required Dealer Action
Inform service staff of this revised procedure and follow this
method when servicing these motorcycles. Replace section
1.21 STEERING HEAD BEARINGS. Place the included
pages into all 2009 Touring Models Service Manuals (Part
No. 99483-09) that are in use in dealer service departments
as well as unsold inventory.
1. See Figure 1-37. Turn handlebar to the right fork stop to
access grease fitting at the left side of the steering head.
2. Inject Special Purpose Grease, Part No. 99857-97 until
it exits from the top and bottom of the steering head.
1. Raise the motorcycle so the front and rear wheels are
lifted the same distance from the floor.
2. Verify that motorcycle is in stock configuration. Remove
all non-factory accessories, since they can influence
front end swing momentum (and lead to improper
adjustment).
3. See Figure 1-38. Turn the front wheel to the left fork stop
and then let go. The wheel should swing from side to
side, finally stopping in the swing specified in the table
shown below. If it stops in the lesser number swing, it
should be at or after the straight-forward position.
4. If the clutch cable or main harness appears to be influencing
swing momentum, proceed as follows and repeat
the previous step:
a. Clutch cable: Disconnect clutch cable from hand
lever. Release cable from P-clamp, remove from
inner fairing, or release from cable clip on instrument
nacelle depending on model. See 2.25
CLUTCH CABLE.
b. Main harness: Remove the rivet and P-clamp to
release main harness from steering head. Secure
P-clamp with a new rivet when procedure is complete.
NOTE
A steering head that is too tight can interfere with the
vehicle's ability to absorb a weave. A steering head that is
too loose can interfere with the vehicle's ability to absorb a
wobble.
5. To correct a swing pattern, see 1.21 STEERING HEAD
BEARINGS, Adjustment.
1. Disassemble motorcycle as follows:
a. FLHR/C: Remove headlamp nacelle. See 2.47
HEADLAMP NACELLE: FLHR/C.
b. FLHX, FLHT/C/U: Remove outer fairing and radio
or storage box as equipped. See 2.37 UPPER
FAIRING AND WINDSHIELD: FLHX, FLHT/C/U
and 7.33 ADVANCED AUDIO SYSTEM respectively.
c. FLTR: Remove instrument bezel. See 2.42
INSTRUMENT BEZEL: FLTR.
2. See Figure 1-39. Loosen pinch bolts (3) on lower fork
bracket.
3. Loosen the fork stem nut (1).
4. See Figure 1-40. Fashion a bearing adjuster tool using a
drill rod 1/4 in. (6.4 mm) in diameter and 16 in. (406.4
mm) long.
NOTES
● See Figure 1-39. Turning the bearing adjuster nut (2) as
little as one notch will make a noticeable difference in
the swing pattern.
● Tap forks with a rubber hammer while turning adjuster
nut to prevent forks from binding in lower bracket bores.
5. Turn bearing adjuster nut (2) as follows:
a. To decrease the number of swings, rotate nut clockwise.
b. To increase the number of swings, rotate nut counterclockwise.
NOTE
Original equipment fork stem nut has a blue dye coating. If a
replacement nut is being installed, the replacement nut will
not have the blue coating.
6. Tighten stem nut to 70-80 ft-lbs (94.9-108.4 Nm).
NOTE
Torque of the stem nut will affect the swing pattern.
7. Recheck the swing pattern and adjust as necessary.
8. Tighten pinch bolts to 53-57 ft-lbs (71.9-77.3 Nm).
9. Verify that the fork stem nut is tightened to 70-80 ft-lbs
(94.9-108.4 Nm).
10. Recheck the swing pattern and adjust if necessary.
11. Assemble motorcycle as follows:
a. FLHR/C: Install headlamp nacelle. See 2.47 HEADLAMP
NACELLE: FLHR/C.
b. FLHX, FLHT/C/U: Install radio or storage box (as
equipped) and outer fairing. See 2.37 UPPER FAIRING
AND WINDSHIELD: FLHX, FLHT/C/U and
7.33 ADVANCED AUDIO SYSTEM respectively.
c. FLTR: Install instrument bezel. See 2.42 INSTRUMENT
BEZEL: FLTR.
12. Install any accessories that were removed during the
checking procedure.
