There are more changes than you would think by just looking at the 07's..... NEW inner rocker cover and gasket. NEW head gasket that is coated. NEW TPS , tangs positioned at 1 and 7 o'clock (4 and 10 on previous models). NEW throttle body manifold pins positioned at 6 and 12 o'clock (2 and 8 on previous models). NEW primary chain cover has added material to the casting. NEW redesigned oil pump. NEW inner airbox functional cover design. NEW Pirelli tires. And also a few NEW things on the Uly too. Side note : 07 Sportsters have the Buell designed EFI with a TPS also. | ||

Glad to hear that some ‘refining’ went on for 07  | ||

Actually, the XL ESPFI system is not the same as the DDFI system. All EFI systems rely on a TPS of some sort. The XL EFI system utilizes a Delphi Mass Airflow EFI system, narrow band O2 sensors on front & rear head pipes. The Buell DDFI uses a Kimbal/VDO AlphaN EFI system, single narrow band O2 sensor on the rear head pipe. The XL EFI system uses an Idle Air Control (IAC) motor to regulate the idle speed, whereas the DDFI still needs to have the idle set via adjusting cable. The XL EFI system also uses a MAP (Manifold Absolute Pressure) sensor on the induction module to regulate injector pulse width & spark timing. XL EFI utilizes a Crank Position Sensor to regulate spark timing, where the DDFI system still uses the timing cup, and static timing is still part of the service procedure. The other new stuff I'll need to wait and see, as we haven't received our new Sporters yet. Also, H-D has incorporated a Clutch Interlock system, so that you can not start the bike in gear without disengaging the clutch. Chris | ||

Which fuel injection system is preferred? | ||

About freakin time. You would think this would be a large liability issue. | ||

i cant start mine in gear now, it an 05? | ||

We're talking about H-D's Buell isn't that stupid. | ||

oh speaking of that, a buddy of mine has a 94 ( i think ) soft tail. we were getting off work and we were talking and he started his bike and it jumped forward and almost got my bike, i thought that it was weird that it didnt have that, but he said they did like the year after. but maybe the sportsters are a little behind times. | ||

Sorry for the delay in getting back. Actually, it's a trade off as far as which EFI system is preferred. The DDFI system requires more attention & maintenance, but costs less. The adaptive fuel value feature is both a blessing for the learning ECM aspect, but a curse if you run out of gas. Trust me, if you run out of gas on a DDFI bike, you will need your AFV reset to 100%. The Delphi system is pretty darn nice to be honest. The H-D/Delphi ECM is considered the most robust in the industry. The IAC motor means that you always have a consistent idle regardless of engine or environmental temperatures, for the most part. Unfortunately, it is more expensive (how much more I'm unsure of), and the addition of more sensors means possible higher rate of potential problems, but both offer pros and cons. Also, there's a big green 6 on the face of speedos on big twin models to let you know you're in 6th gear. Thought that was pretty funny too. Chris | ||

What exactly is different on the oil pump for '07? |
