I am not talking about my 07 SG. I know a guy thathasan 06 Ultra EFI 2600 milesthat is stock andit coughs or farts thru the air cleaner like a carb.

 

Either rich or lean makes them pop through either the intake or exhaust. I'm not positive which, probably lean makes them pop through intake side as HD'S are lean at low rpm's from the MOCO for EPA compliance. And, if hedoes anything to affect air flow, that will lean it more. There are many posts about this on the forum. I suggest you let him have your PCIII

 

My buddy has an 06 that was stalling. he told the dealer and they immediately put in two new injectors FREE on warranty. Problem solved! Try that. apparently 06's had a problem but no factory issued recall.

 

I have an 06 EG Std.
Would cough sometimes or idle low. Plugs showed hot burn.
There is a tech bulletin changing the FI from 8 degree to 25 degree.
Bike runs much better and even with muffler change to VandH ovals.
Plugs look normal.

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.
