Good day, ladies and gents! New member here. Just bought this 2000 Nomad today. Test rode fine. After about 40 minutes and 30 miles I gave it full throttle and it started to go, then bogged down, started to go, then bogged down again. It continues to do it as long as I keep the throttle pinned. Definitely didn’t do it in the first 10 or 15 minutes. Has me a bit concerned. Absolutely beautiful bike, but I feel like a fuel pump is in my future. Although, the guy did say that it was recently replaced. I’ll have to check with him.

I experienced this on an '07 1600, never did figure it out. I swapped fuel pumps, ECU, and spark plugs, all to no avail. Troubleshooting suggestions from various forums included the coils, and possibly the EFI wires where they connect to the cylinders. Someone suggested they'd got kinked and shorted out once the bike warmed up. I was roughly 75K miles into that motor at the time.

I couldn't figure it out and it was really messing with vacation, so I parked the bike in '15, and have it awaiting a full work-through some winter. That happened when I was in the middle of my annual Sturgis migration, a (then new) Indian was already planned for, so I picked one up and have been enjoying it every since.

No idea as to what's inside the tank, I haven't seen anything like it during my disassembly. The pump and filter are a single unit, with nothing else in there.
