This is a follow up to a 2014 thread that I posted regarding my newly converted to efi 2002 FLHTCi. The bike is a 103" with Syke Performance (HTT Member PanHeadRed) heads and cams (SP232G). Bike was originally tuned by HTT Member Black Hills Ken at Black Hills Custom Parts in 2014 when it was still using a 40mm CV carb and White Brothers e-series 2 into 1 exhaust. The bike has had a small increase in compression now and I am using a HPI 51mm TB with 4.3gps injectors. The bike was tuned with a Power Vision by Ray Hulten at Hulten Speed Sports. I switched to a new Fuel Moto e-series in 2018 and also had a FM Jack Pot collector. I had the bike tuned for both. Interesting comparison between the two exhausts. The head pipe is the same for both collectors. Runs were done in 5th gear. Link posted is original thread from 2014 with build details. Current build detail is below with anything new denoted with a (*). I'm pleased with the conversion to efi and the results.

PanHeadRed, Ray, Vic Chichester and Durwood offered some great advise with this efi conversion.

Nice numbers for a 103, the kind of numbers I'd like to have. Another good tune from Ray and another good combo of parts.  :bike:

 :up: Klammer76.   Fun early TQ curve in a bike you've owned for 18 years and that has been rode and put away wet a lot of miles.  Nice to see you renewed the heart and soul of a machine you are connected with, like a best friend.  That's one thing guys with the newer bikes that swap every couple years won't feel or understand.

Congrats on a successful conversion from carb to Delphi EFI.

Thanks Bagger. This was mostly a post to see the difference between the Jack Pot and e-series collectors (mufflers) for others that are considering them. They use the same head pipe. I have always been and still am a fan of the e-series, good power and mellow sound that gets better with age. The Jack Pot really out did it in this situation. Comes on way earlier and carries further. After 19 years I was looking for something different and am going to use the jack pot muffler for a while. I was surprised the e-series low end TQ wasn't there sooner this time. It was also run with 10 & 12 discs, it really didn't like that at all. 14 & 16 were good with 14 being better. My original, White Bro's muffler used 17 discs.

Finally got a chance to ride it yesterday. Did 250 miles. Yes, it runs really well and the throttle response from the efi is great. It was worth the conversion from carb in my book. The Jack Pot is pretty loud. I'm told it will mellow a bit with some miles.

Did you have a donor bike that you swapped the efi components from? Im curious how difficult the conversion was.

Had my bike back to the shop for some tweaking on the tune. The bike runs great but fuel mileage was down. With the CV carb I got a consistent 38 mpg solo. Two up would show 40 to 42 at times ( I ride less spirited two up). After conversion and last winters work it was down to a low of 29, mostly 33 or 34. I tour on the bike so some tweaking was done.

I brought along my original White Bro's e-series muffler with the 17 disc's I always ran with it. I wanted to see how it compared to the Fuel Moto e-series that I had tuned along with the Jack Pot. It did well compared to the FM e-series runs but can't run with the Jack Pot. The Jack Pot is fun and is breaking in at 2000 miles. It is loud if on the throttle. The motor really likes that combo. The White Bro's muffler was run on the FM header. Dyno sheet lists it as a supertrapp, that was a typo. I think with a few disc's removed the TQ would be a bit better down low. The HP surprised me. A full tune also would be interesting with it. The 14 & 16 disc e-series runs are the Fuel Moto e-series muffler

Just a comparison if anyone is interested with a 103. My 103 TC nowadays is on the low end of the scale with the numerous 117's & 124's that are very mainstream now.
