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.

Now doing it pretty much off idle. Went for a ride and almost couldn’t accelerate without the stumbling and bucking. Luckily, I wasn’t far from the house. Also, when I shake the bike from side to side I hear a very pronounced “clunk” sound with the gas sloshing around.
I had a Honda VTX 1800 awhile back that had sort of a similar issue. The entire fuel pump assembly was gummed up terribly. Ran fine at idle, also revving the engine cause no issues. Only under load did it do it.
This bike had been sitting “for a year”. New fuel pump, filter, fluids, etc.
So I sort of figured out what the clunking is. Gonna have to wait to get in there, but I found a small (maybe 1" to 1-1/2") round black rubber or plastic ball with a threaded stud coming out of one side of it. Maybe a float? It's obviously supposed to be attached to something. I've looked up Kawasaki parts and am unable to identify exactly what it is. I'll try to get a picture, but it's going to be difficult.
This is the best I could do. Couldn’t get the phone to focus. It's just rattling around in there.

Changing plugs this afternoon. The old ones don’t look bad but I was told that they were NOT changed when pump, filter, etc. was. Lord knows how old they are. The front tire has a 2004 date code 😮 Also been looking for a new set of tires. Seems none of the normally recommended sets (Commander 2 or 3, American Elite, etc) have front tires available. As much as I hate to put D404s on, I may have to.
Regardless, the tank needs to come off. Looking forward to that 😂
Got it all cleaned up and put back together. It’s definitely a float. But I think it was installed wrong. Definitely haven’t heard another bike make a clunking sound due to the in-tank float. One other thing is a high idle. Sometimes it settles out and sometimes it doesn’t. Bike also seems to shake a bit more than it should.
