While the number for original factory part might be the same for the carb and fuel injected versions, it makes me wonder if there would be a difference with fuel injected if the alternative is used.
The timing thing makes sense since original factory part requires no timing when mounted in the factory position.
Also makes sense why a poster a few years ago could not get it to run with aftermarket part on a fuel injected road king...probably mounted it in the same time position as original factory part and was off timed.
I guess the three wire connections would be the same.
If the wires connections are different then i guess some posi-loc or posi-tite could be used to connect wires easily.
The cup does have a different part number between carbureted in fuel injected. However the cam position sensor wiring and part numbers are identical therefore it should have worked for him I don't understand why I didn't.

Maybe it was the location/timing of cam position sensor.
The EFI factory part is installed with bolts going through the single bolt hole on the left and right side of the sensor plate. No timing of motor.
Original cam sensor part is probably matched to cup so that is why no timing was required.
It would seem like yours requires timing of motor (with rotation of plate).
If the someone tried to install the aftermarket sensor in same position of the original factory EFI cam sensor then maybe that caused the motor to be off time.
Wondering if it is a cup thing with the EFI or the position of sensor on plate.
Either way it might be a solution if folks remember to time motor and remember the safety of bank angle sensor will be bypassed.

Now I understand you. I didn't realize that the base plate of the cam position sensor was a fixed position on the injected bikes. With the new one being adjustable it shouldn't be an issue. With it being $40 it's not a lot lost to find out.. hope this helps everybody for the future.

I learned from converting my '98 ultra from efi to carb that the cup is different. The pick up should work as long as it has the correct cup.

So it sounds like the Standard MC-SPA3 will work, just gonna have to play with the timing to get it right. That's great news!!!! Thanks fellas!!! I'll get it ordered & check back in with updates!!

This is the part and it has the holes for the EFI or to be used as an adjustable one. Different holes used is all..

Amazon Amazon

I run one of theirs in my 98 RK.

To be clear.
You run that plate in the link on a 1998 road king that is fuel injected.
On your 1998 road king with fuel injection, do you bolt in the small single placement holes or do you have to time the motor?

Excellent question!!! Sensor came in today, & I'll be putting it on tomorrow.
For the record, the pigtail wiring looks a lot shorter than the stocker, so I'll probably be splicing it into the old harness.

Don't splice it. It'll reach... I would replace it exactly how you found it, according to the position you took the old one out..

Correct. 1998 RK EFI.

Bolted in at the stationary holes provided on the plate. No timing necessary.
