Bought a bike that sat for years, dies on slow throttle roll on

Hello All,
I recently purchased a 2006 VTX1300.
It has sat for years and didn't run at all when I first got it.


I have cleaned out the bottom of the carb (the various jets and the float bowl etc.) and I have now gotten it to turn over and idle as long as the choke is pulled out. At full choke it idles extremely high... High enough to pull the bike and my 250lb body up hills when I let go of the clutch and apply no throttle.


Anyways, when I gently roll the throttle on, the bike bogs down and dies. If I floor it or do it quickly enough it will rev up with no problems.


After research it sounds like it could still be the potential problems: pilot jet, accelerator pump, vacuum leak?


I was hoping that this video might be of some help in diagnosing the problem. You'll see that when I gently use the gas the slide kind of shudders up and down and the bike wants to die.

Any thoughts? I'm thinking perhaps it may be the pilot jet because I didn't have a wire small enough to fit through it entirely. It was small enough to clean out the side holes on it, but not the main passage. I did soak it in carb cleaner for over 20 minutes though so I was thinking that should have been plenty of time to break up the junk.

Please edit your profile adding a location so maybe one of us near you could be a friend and help iron it out. Charlie D has a tutorial on carbs that most will swear by. Don't go doing or changing a whole bunch of things, do it step by step and check result after every step. Otherwise like chasing your tail.
