My bike is backfiring a bit when I get off the throttle. I've not too long ago put a Remus exhaust and a Rhinewest chip in it. Since the exhaust is a little louder than stock, it is more noticeable. Someone told me that the throttle position sensor baseline might not be set correctly. I'm not talking about the procedure where one twists the throttle three times with the ignition on after resetting the Motronic. I'm talking about the sensor itself and what the voltage readings should be when no throttle is applied. Where do I check the voltage on this? I don't know if this has anything to do with an idle problem I've noticed either. The idle rpm is around 1500, but sometimes when I'm just sitting at a light, it will go up to 2000 and then drop back down to 1500 repeatedly. Any ideas? I'm getting ready to install the latest throttle modification, so I figured this would be a good time to address these other issues.

I'd first check the torque on your header and your seal around the exhaust can itself. We were having to use a light glob of RTV. Be sure no hoses have popped off the fuel rail.

You can sync throttle bodies with a four stick mercury gizmo and a special 90 degree screwdriver.

Guess who has them and would let you use them?
I'd have to come down there to use them, I'll bet.

I have the same set up on my '00. :yeah: I routinly experience the same issue :confused: The solve that I noticed worked for me was to adjust the can. On mine, the can tends to slide back from the pipe where the clamp is, I.e. a very little exhaust leak. it has not been that big of a deal, only adjust it when i get under her. After some time you can almost predict the backfire. Time it right and you can scare those harleys :dance:

I don't think the backfire has anything to do with the can being loose. They put RTV on the joints when they installed the Remus and everything looks OK. Rather the timing or throttle bodies or the TPS being off sounds like a more logical explanation.
