2006 dyna 8 degree injectors
 

I have been looking at lots of things here on the forum (very impressed) and ran across the 8 degree and 25 degree debate. I went out the the garage and looked and I have the 8 degree part #. The bike runs great (some popping on decel), should I bring this issue up to the dealer to upgrade them to the 25's ?????? or just leave well enough alone.
Let me know what you guys think or have done in this situation.
Thanks
Brandon

I had mine changed out at the 1000 mile service........much better performance and no charge so why not?:eek:

Take the bike for a test ride.

Whenever I ride in a parking lot and try to hold the throttle steady at 18-20MPH (first gear) the bike surges like crazy. I'm taking it in next week for the injectors and am hoping it fixes it.

RE: 2006 dyna 8 degree injectors
 

I've got 8's and my bike runs PERFECTLY. No need for me to change anything. There are many others on this forum that run the 8's as well. It really all depends on how your bike runs.

RE: 2006 dyna 8 degree injectors
 

I just got mine chnaged out...much better that the 8s. Mine ran great with the 8s for while but after 4k developed some problems.

RE: 2006 dyna 8 degree injectors
 

After reading the posts on the forum, I called my dealer about the 8's verses the 25's. My bike is a mid-year 05' FXDLI (mfg. 3/05). They said they would check and if they are the 8's, they would be replaced under warranty. I had the Stage I and Python's installed at delivery but it has always "popped" on decel and will surge slightly at low speeds. My question is this: Most of you are reporting this issue on the 06's. Was the 05's included as well? The dealer knows the year of my bike and did not hesitate about offering to check it out.

RE: 2006 dyna 8 degree injectors
 

The issue was with the 06 FI Dynas....it's not a recall but a TSB. But if you are having issues your dealer should have it fixed N/C.

SERVICE BULLETIN
M-1185 February 20, 2006
FUEL INJECTOR/CALIBRATION CHANGES FOR 2006 1450cc
BIG TWINS
®
Purpose
It has recently been determined that the 8
°
angle cone spray
fuel injectors used on 2006 1450cc Big Twins may cause cold
start and/or driveability problems on some motorcycles.
In the interest of promoting customer satisfaction, the 25
°
angle cone spray fuel injectors used on CVO 103 cu. in.
(1690cc) motors will be installed on all production Big Twins
beginning on or around February 13, 2006.
Additionally, Harley-Davidson will provide for the installation
of 25
°
angle cone spray fuel injectors on those motorcycles
where use of the 8
°
fuel injectors (part number 27625-06) is
determined to be directly responsible for cold start and/or
driveability problems. See REQUIRED DEALER ACTION.
NOTE
Due to changes in the manufacturing process, the part number
of the 25
°
angle cone spray fuel injector is changing from
27709-06 to 27709-06A. This fuel injector also will be
stamped with the words “25 DEG” for easy identification. See
Figure 1.
Motorcycles Affected
Only 2006 1450cc Big Twin model motorcycles that exhibit
cold start and/or driveability problems directly related to use
of 8°
angle cone spray fuel injectors (including those subsequently
equipped with P&A Screamin’ Eagle 1450cc or
1550cc Performance Kits).
Required Dealer Action
1. Adhere to the flow chart in Figure 2 when handling customer
complaints regarding cold start and/or driveability
problems on affected motorcycles.
2. If the flow chart indicates that the fuel injectors are the
source of the problem, check the part numbers stamped
on the fuel injectors. While standing on the left side of
the motorcycle, the part number on the rear fuel injector
can be easily read with the aid of a flashlight.
3. If required, remove both 8
°
angle cone spray fuel injectors
following the procedure in the applicable 2006 Service
Manual. Install 25
°
fuel injectors, either part number
27709-06 or 27709-06A.

M-1185 2 of 2
NOTE
Always replace both 8
°
angle cone spray fuel injectors on
affected motorcycles. Never mix 8
°
and 25
°
fuel injectors on
the same motorcycle.
NOTE
If the part numbers on the fuel injectors are rubbed off or otherwise
unreadable, count the number of orifices or holes in
the injector nozzle. The 8
°
angle cone spray fuel injector has
just three holes, while the 25
°
has six. See NOZZLE END in
Figure 1.
4. Update the ECM calibration. For those motorcycles
equipped with P&A Screamin’ Eagle 1450cc or 1550cc
Performance Kits, refer to h-dnet.com for the correct calibration
P/N.
Credit Procedure
Complete a separate warranty claim for each vehicle
serviced. Reference Service Bulletin M-1185 in the
“Comments” or “Notes” section and be sure to include the VIN
of the vehicle on which the service was performed. Fill in the
rest of the claim as follows:
Performance calibrations require pre-authorization from Technical
Service to be considered for warranty coverage unless
listed on the SWR.
Upon receipt of the properly completed claim, you will receive
the labor credit shown above.

RE: 2006 dyna 8 degree injectors
 

this guy (KB) has an above average dealer ...I have the 8s and my runs well too when I inquired about the change with
the dealer they wanted to "look" at it and see how it was performing,I.E. starts and surges I knew it was fine and was not going to lie about it nor argue the point ...I may be mistaken but each injector is 92 dollars out of pocket I stayed with the crazy 8s-phucum

RE: 2006 dyna 8 degree injectors
 

There is no debate, if your dealer will put them on without a hassle then have them put the 25° injectors in. My dealer ordered mine the day the bulletin came out and installed them a little over a week later around the end of February. I had the cold start problem after the bike sat over night no matter how warm it was as I live in Phoenix. It would also cough and quit sometimes before it warmed up. Everything was fine after the 25° injectors were installed. Also they started installing them on all big twins after the middle of Feb. coming out of the factory.:D
