My guess is that it was just a bit of goo in the line -- the Seafoam seemed to help it at the time.Any luck? I had similar issues a few weeks ago and am just getting to this now. Mine started no problem, idles fine. Then on take off sputtered and died. Started again and got it moving but it was literally clunking along - sputtering - coughing... this isn't in one range of throttle position either (I know that pilot and main jets operate at different throttle positions).
Picked this 2000 VN1500 after my 98 VN1500 crashed. And I am guessing that the last guy didn't do any or very little maintenance as there was a few things I had to clean up when I got it.
So I am going to start with this:
- Clean air filter which I have already done. Dried, oiled and ready to install back into the hypercharger.
- Replace plugs;
- New Oil and Filter;
- Check fuel filter;
- Pull Carb and check jets and float.
- Tune Carb and run Seafoam just as a preventative and to clean up the rest of the 'arteries' in the bike.
The first few will be simple to do and adjustments to tune the carb should be easy enough as I have pulled my old one several times as I modded the engine and exhaust.
I'll post results and what I find here.
More to come.
Bummer about the pump but great news on the Seafoam working for you.My guess is that it was just a bit of goo in the line -- the Seafoam seemed to help it at the time.
Now if I could just fix the water pump that died...
Hi there,Just a shot in the dark since it sounds like you're losing the fuel flow: have you checked the gas tank vent hole under the gas cap? No air in means no gas out.
Pull the carb carefully keeping it verticle and the fuel (and any crud) in the bowl. Hopefully you can pull the bowl with the fuel still in it to see what crud/water is in it.I will pull the carb tonight after work (I am hoping) and report back on what I find.

Did it idle fine just not accept throttle?
Hopefully you just have some accumulated water/crud. Vacuum carbs can be deceiving because they blur what system you're running on. You may also have an only partially clogged (restricted) main jet. While you've got it apart you can see if it was jetted for the less restrictive intake.I had a problem with the carburetor a few years back and when I pulled it there was varnish/old gas deposits in the bowl.
So I am hoping that is the same thing this time around. It seems strange that this occurs through the entire range since pilot and main jets operate at different throttle positions.
