HI,

Has anyone had a problem with their EFI 96" engine stalling at idle after a run. It happens intermittently. I have managed to bump start it again but the revs has to be kept above idle or the engine will stall. I have been able to turn of the ignition switch off and then back on and restarts no worries and maintains idle. Suggestions appreciated.

Cheers,

T

Yeah - sorry about lack of info on the bike - was not thinking real well.

2007 FXDB,   510 S&S cams,   S&S slip ons,   K&N breather,    Motohansa [Doebeck] fuel card.

I took it in to the mechanic today who did a diagnostic check and he informs me there is two faults registered and both point to the crankshaft positoning indicator. So, we are going to change that tomorrow and see how it goes. Will give feedback on the result.

Cheers,

T

 

 

 

g.day turtle, here is some infomation you might be interested in. it ccomes from the screaming eagle EFI race tuner kit manual
i have a 07 street bob as well and it does the same sometimes.
last week i conned the leads out of a dealership to hook my bike 2 the laptop, ill let you no if i come up with anything.

cheers Stewy
07 street bob
lots of bites and pieces.

Heat Management System
The ESPFI systems on the following EFI-Equipped models: 2001 - later Softail, 2002 - later Touring, 2004 - later Dyna, and 2002 - later V-Rod also incorporate a sophisticated heat management system that operates in three-phases to keep things cool in extreme conditions.
Phase I: If the ECM detects engine temperature above approximately 300° F while moving or stationary it reduces the idle speed. A lower idle speed produces fewer combustion events per minute and that reduces engine heat.
Phase II: If the ECM detects an engine temperature that’s still drifting higher while moving or stationary it richens the AFR. An increased amount of fuel in the air/fuel mixture has a cooling effect on the engine.

Introduction – 2.6
Phase III: If the ECM detects an engine temperature that’s still drifting higher while moving or stationary it directs the fuel injectors to skip, (only when the bike is stationary) and not deliver fuel on every intake stroke. This limits the number of combustion events taking place, which produces less heat.
The 3-Phases just described function seamlessly, and the rider may not notice the transition from one phase to the next.
Model Year 2007:
New for all Big Twin vehicles there is an optional Heat Management System called the ‘Engine Idle Temperature Management System’ or EITMS. The Tuner software allows the EITMS to be turned ON/OFF.
For those riders who frequently find themselves in riding conditions where the vehicle is subjected to prolonged idle conditions the optional ‘Engine Idle Temperature Management System’ (EITMS) is available. This feature offers limited rear cylinder cooling with the vehicle stopped while the engine is left at idle.
Enabling EITMS will cause the rear cylinder to be shut OFF when ALL of the following occur:
1. Engine Temperature reaches ~300F.
2. And the vehicle is at IDLE.
3. And the vehicle is STOPPED.
Please note:
Customer benefits (for Rider Comfort) – If a customer experiences frequent riding conditions where prolonged idle conditions create excessive engine heat, EITMS offers limited rear cylinder cooling with the vehicle stopped and engine at idle. While enabled, the customer may notice a unique exhaust odor which may be objectionable. The EITMS does not address engine heat issues resulting from other operating conditions.

My 07Bob has done the same on occasion, I looked into it about a year ago and found out it's usually something to do with a little Crank breather hole on the air inlet throat getting blocked, can't remember exactly but if you ask Scotty he'll know, I found out from the US forum but Scotty confirmed that this problem was fairly common. Sorry for being a bit vague but I'm over 50  ;-)

Cheers

Thanks all for advice.

I have taken the bike in to the mechanic who changed the crank position indicator and all appears fixed - thus far. I took the bike for a run yesterday up over some hills and on a good bit of straight as well as some coastal winding road and never had the engine stall after coming to a stop. I am hoping problem is solved but will really know after a 6000km round trip coming up in a couple weeks.

Cheers,

Well, it has been awhile between drinks. The crank sensor was not the fault - it appears. It was the fuel card. That is two that had faulted now with the same fault yet were different brand cards. I hope the fault is finally over as I have installed a SEPT and to date and 1500kms later the fault has vanished.

Have you checked for a faulty Intake Air Control?

cheers
Surly

heard plenty of complaints about this sort of behaviour but mine has never done it so my reply here is useless so ill just go and have another drink sorry

The fuel card was a Motohansa [Doebeck] fuel card. I mentioned this in my second post in this thread.

Also, was just letting youse know the fault has been corrected with the SEPT. Thanks all for your assistance.

Cheers,
