Unfortunately Chunky River HD never ran any of them, just keep replacing parts (fuel level senor wiring harnest, fuel level sensor itself, float in tank). After $280 worth of guessing, problem not fixed. I took it to a local independent cycle shop here and they DID run the five tests as HD suggests, and found the float in the tank was intermittently stopping (6 out of 8 tests showed no signal from float). They replaced the float, which is part of the fuel level sensor or attached to it (they bought both together). That fixed the gas gauge, low fuel light and DTE problems all at once.

It pays to run the tests that HD suggests to find a problem, and stop guessing at it and replacing parts.

Wouldwould that be why when I pull the throttle it barely wants to make any difference until I get to the full throttle Mark? I understand that it's not like my Fatboy so it doesn't have cables per se but it's a 2011 haven't had any problems with it it's been sitting for about two or three weeks and it's been on a trickle charger but I got on it and it started it up and it started up just fine when to go throttle it and no response from the throttle until I got twisted all the way to the end
