Default 2010 Injectors

I have a 2010 Tri glide with the catalytic Converter, lean and hot. All the 2010 MAPS look lean to me. I quess Harley don't want to dump to much fuel into that CAT.

I want to do an injector upgrade! I believe the Injectors for the 2010 103 on the touring are the 4.9gps variety. I have found some 6.22 gps for the 103 but know I will have to tune.

I live in a rural area and no one within a couple hundred miles can dyno a Trike. I would like to find some 5.3 gps injectors as the ones HPI sells for the 06 - 08.

Does anyone know where I can find some 5.3 gps injectors for the 2010 103?

Will I be able to richin up the AFR with these without a Map/tune? I have the XIED's installed but am looking for a little more cooling and performance!

Please define "Looks Lean"... If you are looking at a TTS or SEPST map, then you can manipulate the Closed Loop area to a slightly richer mode, and if you are concerned about the idling and lower TP's, then you manipulate the portion of the table....

Just because the Closed loop area is in a 14.6 setting, doesn't mean it HAS to stay there.. Once the VE's are synchronized across the board to the desired AFR, you can set the bike to run in Open Loop all the time if you want.... Heck, you can have it at 13.0 : 1 if you so desire..... Have you read and understood the tuning manual for your particular device????

Asfar as the 5.3 injectors, 27796-08 is the Harley PN... These are designed for the 58mm Induction module..... IMPO, these are too big for a 103 Stage I Motor....

I dunno where you are getting your info from, but it is erroneous..... Properly dialed in, your bike can run like a scalded dog.... With the stock injectors.

I'd like to know where he is getting his info from too. He states he has XIED's. I wonder where he is getting the MAPS to look at? If he's looking at AFR tables he more than likely is tooking at SEST or TTS like you said. but as you pointed out, alls he has to do is change the Cruising range to 14.2 or so. No need for new injectors.
