Im new here and was looking for some help my FXDI stumbles between 2300 to 2600 rpm it doesnt do it accelerating just criusing and crack the throttle a little bit and it will start stumbling the higher gear the worse it gets I have revaluation 107 big bore kit and S$S 585 cams with Vance Hines fuel pack intake kit and pipe they programmed it via Bluetooth and I have called them back and they said its something else I sprayed choke cleaner around intake gasket with bike running for leaks and didnt find any it idles great and runs great when you get past these rpm range any help would be appreciated

Start by checking the basics:
- Check for DTC Codes https://www.hdforums.com/forum/dyna-...-2008-a-2.html
- Check your spark plugs for condition, proper gap
- Check you spark plug wires for condition, integrity, the connection at the coil and spark plug
- Confirm your battery connections are tight at the batter and ground, starter
- Take another look at the throttle body
- check that it is not loose in any way
- check fuel injector connections - on, snapped in place
- Check your fuel line connection from the tank to the throttle body

Like he said...
.lots of possibilities as there is enough changes it could be anything, but engine stumbles usually are fuel related, at least in my experience. Could be your tune as well....I would have it professionally tuned on a dyno if it’s still there after doing the above checks....

Ok Checked codes and didnt get anything plugs are new and look good a light brown on porcelain wires are new checked Throttle body plug and cleaned it with electronic cleaner throttle body is tight checked for intake leak agian I called V&H already and they said the tune is correct I think its a fuel problem but my friend said he thinks a sensor problem TPS maybe I read about crank and cam senor or temp sensor making problems but I would think it would be doing in it all the time not just certian rpm

From: Depends on who wants to know.........and why.
I'm having the same problem with my FXDB. Let me know what you find out, let us know. I'll do the same. Mine is a little diiferent in that the idle hangs up, revs up and down when I'm stopping until it finally settles down, spits and sputters at low speed/low gear while accelerating then clears up.

dude why on earth would you go ordering sensors blindly? certain rpm would lean more towards an issue with that certain pulse duty of the injectors over a sensor....i would have pulled them, looked to see what shape they were in, maybe soaked the tips in some injector cleaner then gone and tried to ride with some injector cleaner in the fuel first. that v an h tuner doesnt show you the status of your sensors? glad i went with tmax.
