Maybe it actually runs out of fuel.I have been reading up on the V-Rod sputtering symptoms and I don't see any of the signs that have been mentioned. Basically my bike feels like it hits a rev limiter or runs out of gas at higher than 4000 RPM. It runs great up to that point. This is what I have done so far...
Installed new plugs - old ones looked to be burning good though
Ran the diagnostic and get "none" in all 3 areas
Checked to see if I am getting the misting action from the fuel flange and don't see anything out of the ordinary that I can tell
Maybe it actually runs out of fuel.
If no one has a better idea, I'd look at the air filter first (take it out and test drive it without), then I'd look at the fuel sock and filter inside of the gas tank. With 19,000 miles I wouldn't think that the air filter is clogged, but it's the easiest of the two to check.
While you're in the airbox, make sure that your throttle valves are opening fully.
is the tank full?OK I went out and checked a couple more things.
Fuel pressure - holds steady at 61 PSI even on heavy revs
I looked in the tank again with the bike running and there are bubbles rapidly coming up through the gas - not a mist like I was told to look for but pea sized bubbles steadily coming up. Is this the culprit?
what did it run like before you needed to replace the battery.? if you are not sure wheter its been tuned for those pipes then you need to find out by takng it to someone who can scan the ecm,or check for a fuel management module.some fuel managers need to be initalised after disconecting the battery.fuel flanges as already covered in this thread are an obvious culprit too.
This is hard to tell, if it were tuned with a SERT module & software, the HD Tuning Cartridge, you would not know w/o plugging her into a tuner, this equipment is temporarily attached to reprogram the ECM.Sorry for the lack of details. ................ From the information that I have gathered I don't think it has a tuner of any sort because I had to install a new battery and from what I see the tuner would have been in there somewhere - Right?
