Assuming a 2000 DWG. All you are reading is speedo error codes. In order to read the ECM/ICM codes on the early bike you need to jumper a wire on the diag connector and watch the flashes of the engine light. IIRC the codes in the link are valid for the ICM (carbed bikes) except for many do not apply. It's a reduced set.

My bet with the age of the bike, it's a 17 or 18. CKP sensor error.

Ok, thanks for this @Max Headflow . I followed the instructions and was able to pull two codes. From the looks of it I have a 42 and a 56. That chart on the other site doesn’t make sense to me, how would you read these two?
Ah wait a second: I think you’re right @Max Headflow . I found this on a Road King post:
42 Cam position sensor
AND
56 should be crank position

OK, installed a new crank position sensor and I'm still getting it. Now I'm wondering if I didn't have the cams lined up right....seems weird since I checked it like a billion times, ha! Possibly the cam sensor?

This issue happened after you worked on the bike? Cams lined up?

It would be good to know what you did when taking the motor apart. It's possible the cam timing is off and there is a sync error between the CKP and CPS. IIRC the issue was mainly with the Magneti Morelli systems but I'd guess that it could happen on a carbed bike. There have been issues where running an cam advance gear could cause the issue. At this point you really need to observe the error codes. @Ed Ramberger might know.

You are right everything lines up.
Here is the thing. You are running SnS 509 cams. They have an early intake close and some overlap. You should not be running a stock ignition. I would suggest dumping the stock ignition and going to a DTT ignition. It won't have the same problem. In fact, you'll be able to remove the Cam sensor. It's a worth while change since you'll likely get some pinging with the stock ignition.

Great thanks for the info again. Funny enough I have a Daytona Twin Tech coil, So I guess getting the ICM to go with it makes sense. I had one for my 04 sportster which I had a Hammer 1250 kit in it. Is the one for the Twin Cam 88 programmable like that one? If so, anyone got a good starting point for the 509 cams?
