I'll have to ask one of the parts changers at the dealers. I'll take coincidence any day to get me back on the road.

along with my new Rineharts/Fuel Pack/LoJack. 

I have seen friends with 07 and up Harleys have some really strange problems because the ECU is linked to just about every function of the bike and aftermarket parts have usually been the culprit... I would have tried disconnecting the Fuel Pack and LoJack as a first step in dianosis....

If the problem comes back it's a suggestion where to look...

The following was pulled off of another HD forum. ( I'm just to lazy to type)..............Fuzz

The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).
1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting
sould illuminate, speedometer needle should sweep its full range
and indicator lamps (battery, security, low fuel, check engine and cruise) should
illuminate. The word “diag” should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with
the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing
is the one you are going to check. To move from one letter (module)
to the next, you push the odometer reset button one time. (from P to S to SP to t and back
to P, etc.)
P = ECM/ICM (Electronic Control Module (EFI) / (Ignition Control Module, 'Carbureted')
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button
in for 5 seconds and release. If there are any DTC’s the code will be
displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset
button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part
number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in
and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up.
Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it
down then recheck the DTC’s again by repeating steps 1 to 9.
If the code is current it will reappear.
9 – Press and release the odometer reset button to continue to the next module.
10 – Turn Ignition switch to OFF.

Just curious if anyone else is having this problem:

When driving the bike hard through all the gears, never letting off the throttle at all, leaving it wide open while shifting, my bike seems to hesitate. I'm just wondering if its just the throttle by wire? I have never had this on any other bike. Its almost as if it stumbles between shifts.

[Lo Lo]

Well, I started this post last year sometime, and as luck would have it my Throttle by Wire has crapped out again!  This time I almost had an accident when the idle dropped during a ride in traffic.  Stopped at a red light behind a truck, and when the light was green an the truck in front of me started to go, I did also.  My SERK started to move fine, and then the throttle went FULL OPEN by itself and I almost struck the trucks rear bumper in front of me.  Luckily I pulled my clutch in and stopped before I hit it.  Then I pulled off the road and shut down the bike, waited and re-started.  I didn't want to be left on the side of the road, so I fired it back up and tried to take it easy as I headed for the HD dealership.  About a 1/2 mile away from the dealership, the right side of my SERK started making a horrible clicking noise.  I freaked and was even more anxious to get it to the service dept.  As I pulled up, one of the service techs heard the noises and shook his head.  When I dismounted, he approached me and said, sounds like a short in your throttle by wire.   Needless to say my Harley is back in service AGAIN!  This crap is started to piss me off.  Did I mention my Harley was just in the shop a couple of weeks ago for my TBW malfunctioning a second time since I have owned this CVO SERK?  Well this makes #3!  What the hell is going on?  Can I sue HD if I have an accident from this faulty TBW setup after having several episodes that weren't resolved?  Because next time my TBW takes a dump, I may not be so lucky......

You (or your estate) could sue, but why wait until it comes to that?  For yours to fail 3 times now tells me there is something wrong that no one has found yet.  Get on the horn to H-D to file an official complaint, and follow up with a formal letter detailing the problems and requesting prompt resolution.  Resolution could include sending an "expert" to diagnose and fix your bike, or it could entail buying your bike back if they can't find and fix the problem.  Regardless, document everything just in case.

Also check your local laws on "lemon law" details. You may be able to return the vehicle due to chronic problems the dealer can not fix. I would also consider getting a bit of legal counsel since the incidents are so likely to result in serious injury. You may want to send a letter (just to have it on file) to your dealer outlining your situation and warning them that if they do not take immediate action they will be held legally liable in the event of another failure. It helps to know what your rights are in this situation. This isn't like a motor failure that results in inconvenience, this is an extremely serious safety issue. If it were my bike, I wouldn't be riding it.

Jerry (or anyone), fly by wire throttles aren't a new thing.  Even if new to Harley.  Have you heard of an automotive failure of these in years?  I haven't.  And even the few I can ever remember hearing of or dealing with didn't fail to high throttle.  A definite crock.  A dangerous crock.  But a crock nonetheless.

[brassspike]

I have a 2008 SERK an am now on my third throttle control. First one kept going to limp home. The dealer replaced that one and deliverd the bike with a new control that bound up and would stick as it opened. That was real safe! I had another dealer replace that one. Bike is fine....for now.

Wow   I have had problems with my cruise but nothing like this

Thank you all for the advice.  I feel cheated that I invested all this money into my "baby" and something like this ruins my appreciation of the product.  Ever since I was little, I longed to own a HD.  I grew up riding sportbikes, and dirtbikes, and now I finally get my dream, and it comes crashing down around me with little incidents like this.  Total time I have owned this Harley= 12 months so far,  total time I have had this Harley in my possesion= 9 months.  The rest of the time, it has been in the Service Department broke down, or waiting for parts to be fixed.  To me, that is unacceptable, and maybe someday HD will be able to ride on the reputation of being reliable instead of an icon.  Either way, I have fallen in love with this piece of steel and rubber, (and plastic haha), and cherish every time I throw a leg over my "baby" and take it for a ride...

I will keep you all updated with what unfolds. 
Consulting with an attorney this week.
Do I foresee a 2010 CVO Street Glide in the garage? 
Time will tell...
Did I mention how much I love my SERK...?   Damn it!

There was a recent post on here about changing the blade opening to match throttle position.  Granted it was with the TTS MasterTune software, but maybe they screwed up something when they installed your fuel pak and RH's?  Anything electrical is almost tied into the ECM or very close, especially when monitoring the engine/fuel and air ...

Just a thought.

Right you are Don.  This is pretty old technology, in that it made it's first appearance on cars back in the 80's.  As I've noted several times in the past, all this EFI and electronic stuff isn't new, it's just new to the dolts at H-D.  So far everything they've borrowed from the auto industry they've managed to screw up. 

I haven't heard of any failures in cars that went to WOT since very early in the history of throttle by wire.  The automotive systems have redundant sensors and circuits to allow for continued operation with a fault (turns on the wrench light or check engine light and sets a code), and if they do fail completely they are designed to fail to idle, not WOT.  I can't help but wonder if the aces running the MoCo didn't find another way to cheapen the system by eliminating some of the safeguards.  Based on the cheap crap I've seen in the past few years, it wouldn't surprise me at all.

MoCo one is supposed to be just the same as that, Jerry.....

Update:
Received the bike back fixed.  Service Dept. stated it was my induction module that took a crap this time.  Hmmmmm....  Anyways, picked my SERK up last night and rode it home in the rain.  No issues so far.  Bike is running strong.  Time will tell.  Naturally, I have all the service history logged, with supporting documents just in case.  Stay tuned for my next episode...
