SOURCE: removing gas tank on harley flhtci

remove seat, remove console on top of tank, disconnect wiring from console to tank, disconnect vent line if present, disconnect fuel line on tank, disconnect fuel gauge (up under tank on left side, 3 wires, 4 wire connector, wires are yellow, orange, and black), remove bolt at rear of tank, remove two side bolts up front under tank (coil bracket is there also, carefully cut clamp on cross over hose located up front under tank.
This works better with three hands remove one side of cross over hose, fuel will flow freely so the extra hands are good at "plugging" the hose and the tank. Gently remove tank tilting front of tank as much as you can till you get it clear of the frame, while still tilted at a steep angle put the cross over hose back on.
To make things easier drain all fuel out of tank before reversing the process to reinstall tank. Hope this helps.

Sputtered died


A 22r engine uses a carburetor, and a 22rec is fuel injected. If you have the fuel injected model, the throttle position sensor could be faulty.

Vapor locks


It could be a vapor lock but not likely. Since the introduction of fuel injection vapor lock has been eliminated.
You need to figure out if you are loosing fuel pressure or spark when it will not start back up. Could be a fuel pump relay or ignition module among other things. Even a problem with the vent for the gas tank.

I have a 2007 FXDWG and after riding for awhile, when come to a stop it dies. it will start right back up every time. Today it even hic up'd a few times while riding. Any ideas?


If your bike is equipped with a carburetor, it sounds like it's idled a bit slow. It should be idling at or near 1000 RPM. If it's stock, the carb is jetted pretty lean to pass emissions tests as well. If you can richen it up by changing the slow speed jet up one size step. This will make the engine run smoother and eliminate the spitting out of the carb. If it's fuel injected, you'll need to take it to a shop that can change the fuel mapping. I know nothing about that as I work on the older non-fuel injected bikes.

Good Luck
Steve

1997 fuel injected FLHTC? Hmm. Did not know they had FI that year.

Anyway, the DynaJet sytem needs to be enrichened up a little. The open exhaust probably contributed to the lean running too.
