No powder coated cylinders and dead stock motor. Could excessive lean mixture cause it to run hot, assuming this is too hot for an air cooled motor. This bike cuts out while standing at a traffic light waiting for it to change. Cruising it runs fine, stop it anywhere for 2 minutes and it conks out.
Thanks for helping guys, will alert you when we find a cure.
Anyone have a phone number for any shops that know these bikes, maybe ask if they saw this?

2007 Bulldogs were ALL EFI engines. If it's a Bulldog then it's an EFI engine with O2 sensors so the mixture should be good, baring some malfunction.
Like I mentioned earlier...."The temp sensor is on an intake manifold bolt front cylinder behind the throttle body and air cleaner."
Download the Protune2 software from S&S and connect to the ECM with a (RS232) special cable and a laptop to check the engine parameters, TEMP, O2 etc. while running the engine.
The S&S ECM is doing what it was designed to do, over temperature engine shutdown. This function with others were added to the BDM locked ECM so S&S could provide a two year engine warranty to BDM.
Our 07 Bulldogs don't have a temp sensor or anything on the exhaust port bolts except flanges, washers and nuts.
The following is from Neil (Nomad2day) to me when I was testing. 4/1/2008
Sounds like everything is correct. USB to serial interface you are using, Is it a Belkin model?
Connecting the ECU:
WARNING!
Use the dealer supplied cable to connect the
ECU to your PC. Use of any other cable may result
in damage to the PC or ECU.
NOTE: You may use a 9-Pin serial extension cable
in conjunction with the supplied cable, but the
supplied S&S cable MUST be connected to the
module.
To connect your ECU to your PC:
1. Install the ECU using the separate installation
instructions provided.
2. Connect the supplied Communications Cable from
the 9-Pin socket on the case of the ECU to the 9-
Pin connector on your computer.
3. Launch ProTune II. When there is no ECU
communicating with the PC, the communications
status box at the bottom-right corner of the screen
will flash between blue and black and alternate
between the messages No ECU on COM1: and
Checking COM1:
4. Switch the motorcycle ignition key to the ignition
ON position. Switch the engine kill switch to the
RUN position. This will power the ECU.
Optionally, you may start and run the engine.
5. The communications status box should illuminate
green to show that an ECU is connected and
communicating with the PC software.
The communications status box shows the ECU model
number and hardware revision (55-5002, revision B in
the example above) and the ECU software version
(B831 in the example above). The box to the left also
shows the serial number of the ECU (00029327 in the
example above). This information may be required for
customer support.
Introduction:
If you do not have a serial port on your computer, you
may use a USB-Serial adapter instead. They are
available from computer component vendors. We
recommend the Belkin F5U109 USB-Serial adapter as
the software has been extensively tested with this unit.
If you cannot establish a connection with your ECU:
1. Check that the ECU is powered. The ECU must be
supplied with vehicle power in order to operate.
Your motorcycle ignition key and kill switch
should be set to the ON and RUN positions. Make
sure that the battery level is normal. Try cycling the
power to the ECU (switch ignition off for 15
seconds and then switch on).
2. Check that the cable is connected firmly to the
ECU and the PC.
3. Some PCs may have more than one serial port. If
this is the case, try connecting to the other port(s).
4. The external serial port on your PC might not be
installed as COM1. This is the case on some
notebook computers that use COM1 for other
devices (modems, IR ports, etc). If so, you will
need to change the serial port that ProTune II
checks for ECUs on. Try searching COM2, COM3
etc. instead of COM1. See Serial Port Settings…,
p19 for details on how to do this and for details on
how to detect the port setup of your computer. For
detailed information on the port setup of your PC,
(for Windows XP, 2000 etc.) go to the Windows
Start menu, find Control Panel (which may be in
the Settings menu). Open the System control
panel. Click on the Hardware tab. Click Device
Manager. Under the group labeled Ports the
available serial ports should be listed. The serial
port names will start with the letters ‘COM’. If you
are using a USB to serial adapter,
note its COM number in Device
Manager.
I have not had issues connecting to mine. The new software on the S&S site with try to download as soon as the computer connects and then give a alarm that the ECU is a secure unit and needs the appropiate box file. You can still do the live reading but I am unsure if you can see the alarms anymore. I have the old software if needed.
Here is a link to the manual with all the info you made need.
