sorry, first time posting, hope this isn't to long. Way way too many miles on RT airheads, my 1988 finally quit and move up to a used 2005 RT that had been stored. Picked it up in the midwest, had warranty work done on fuel pump and rear flange. Road east - died on highway as fuel indicator went approached 1/3 tank. Topped off tank (gas station nearby) and road to St. Louis, stopped at dealer. They check computer fault codes (nothing), said it might have been an anomaly. Road east.
Problem not solved, happened again, same place with fuel level. Continued back to east coast, never letting tank drop below half, bike ran fine. Took it up to MAX's, they checked new fuel pump (to make sure correct pump, correctly installed - it was). Replaced pump and cleaned tank (full of a lot of sand and stuff, we think due to bike in storage for two years prior to me buying it). Rode away, problem not solved - it did it again last week. Problem seems to occur when the INDICATED fuel level shows around 1/3 left, but milage readout and level indicate more miles to go.
Mechanics said it might have been wrong fuel pump installed (in that the feed tube was not reaching the lower half of the RT tank, not the case). All my riding has been on old airheads, first time on a 'new' fuel injected, pressurized non-carburated motor, I don't know what to expect, how to trouble shoot, what to do. I don't know what to expect on milage or how the electronic readouts relate to what is actually in the tank, levels, ext. I don't know what the milage SHOULD be, when a 2005 RT with what I think is 7 gallon tank should run out of fuel. Should the thing run out of gas 170 miles into a tank?
The bike is acting like it runs of gas. When it fails, I coast to the side, wait a minute or two and it restarts, then I head for a gas station QUICK!. Sometimes it will do it again before I get there, I wait another minute, rock the bike left to right as much as I can to slosh what ever fuel is left, and then it will re-start and I scamper off. Could this simply be a bad fuel sensor? The computer fault codes they tell me indicate nothing else wrong. Is there a code for running out of gas?!?!
Again, sorry for the length, bike did not come with tool kit nor manual so I'm a little lost as I re-learn so so many things about this complex, fancy and so far temperamental beast. If you have any advice, you can email me directly at email@example.com.
Appreciate any thoughts, thank you all!
