11 Ultra, stock. Slip ons and screaming eagle plugs/wires but no upgrades. 61,500 miles.
Hopped on the bike yesterday to go pick up some food and she was spitting and sputtering horribly under load. Was pretty low on gas, had planned on filling her up on the way. It idles and revs just fine, unless you are under load trying to accelerate. Limped her to the gas station, she took almost 5 gallons so I really don't think it was having trouble picking up fuel.
Filled her up, same issues. She idles just fine, and if in neutral or clutch in it revs with no issues. When you try to take off she spits and sputters. WIll hold speed ok, starts sputtering on the slightest incline or attempt to accelerate.
I'm about 500 miles from the next fluid change. Checked my air filter, it was nasty so put a new one on. Same issue. I have new plugs I was going to do at this change, so went ahead and pulled em. Front looks fine, rear was caked and white, it scraped off. Installed new plugs and checked the wires, no visible issue on the wires. Same issue. It spits and sputters, I really have to feather the clutch/throttle to keep it from dying. Pull the clutch in and she purrs like a kitten. Roll on the throttle in neutral or with the clutch in and she roars.
What do I need to check next? Fuel filter? I've done some research and came across some stories of a temperature sensor, but the symptoms aren't quite the same. Any advice or direction on what to look at is very much appreciated.
