OK, new update. Changed out the stock black injectors to the red and went through the process on volt settings for TPS and cold idle sensor. so far bikes starts and idles good but too cold to take for test ride as we still have some snow and ice to deal with. Another question: would the v-settings still be the same [.275 and .650] for a stage 2 set up? which I've discovered I have. Wayne

 

Until you replace the engine temp sensor you are simply peeing in the wind.
Since the red injectors a larger than the black one the tune will be unnecessarily rich until it gets re-tuned properly for the larger injectors.
Your model bike is well known for engine temps sensors going bad which causes all kinds of poor running issues because the ECM is being told wrong temperature readings which change the fueling.
Hope you find this info valuable to saving you unnecessary work and money.

Thanks Bob. I will continue to search for ET sensor. Don't suppose anyone would know where I might find one? So far, no luck on my searches. Wayne

 

By the way, I did venture out yesterday and drove 3 miles. ran fairly well except for some backfire on deceleration. Before that I could only go maybe a mile and it would bog down, backfire, and only on very little throttle, limp it back home. I'm onto something here. Pulled the plugs that the shop installed, and they are gapped at 32. They replaced my Harley plugs for NGK's. I re-gapped them at 40 and will test that hopefully today. I put the red injectors in because they were in the original throttle body that came on the bike. The replacement throttle body came with black, and I did not know the difference as this is my 1st experiance with EFI systems. So, I now believe bike had a stage 2 kit done that I was not aware of. Thank you all again!! Not ready to give up the ship! Wayne

 

OK. Thanks again for the help. Went on test run and back firing was very minimal and never bogged down. Ran for several miles. Switching the injectors seemed to take care of most of my problems along with corrected plug gap. Went ahead and changed out the TPS and retest rode, that really smoothed out the running with no more backfire. Wayne

 

The original post was long and I completely missed the part about you switching to black injectors from red. That definitely needed to be corrected. If it sat for a long time, run some fuel injector cleaner through it. Techron Complete is what I would recommend. Those injectors are pretty resistant to fouling, but they could have some deposits.

 

Thank you will do!!

 

I am working on a 2000 Road Glide FLHTCI. Does anyone know what the TP settings are for this bike? It is an 88 twin with a Magneti Marelli fuel injection system and it is not an EVO.

 

Hello, I am working on a 2000 Road King FLHTCI does anyone know what the TP setting are supposed to be. It is a Magneti Marelli fuel injection system and it is not a EVO.
