1996 Honda Shadow VT1100C2 idles perfectly but dies when I give it throttle.

Hey everyone,
I’m hoping someone with experience on the Honda Shadow VT1100 can point me in the right direction because I’m stumped.

The bike had been sitting for several years before I got it. I’ve been slowly bringing it back to life.

So far I’ve:

Removed and thoroughly cleaned both carburetors.

Cleaned the jets and passages.

Installed a new fuel pump.

Verified the bike starts and will idle.

Adjusted the idle speed to a steady idle using the remote idle adjustment knob.

Current symptoms
Starts without much trouble.

Idles indefinitely and never stalls while just sitting.

Fuel pump clicks every few seconds while idling (not continuously).

The moment I begin opening the throttle, the engine bogs and dies.

It doesn’t matter whether I snap the throttle open or roll it on slowly—the result is the same.

I also get some popping from the exhaust.

Honda VT1100C2 Won’t Start, Need Help

Hey all, so I’ve been periodically working on my 1996 Honda vt1100C2 for over 6 months. I finally got it to start up just for it to suddenly die on me as I was about to attempt to ride it.

Here’s what I know:

  1. my battery is perfectly fine, I tested it on another battery I have on hand and the bike started up the same.
  2. it can’t be a starter relay problem, the starter relay featured in the video is the new one I just installed
  3. when I use pliers, as you can see on the video it does crank, but won’t start, once I take the pliers off, it dies on me

Before all of this, my front headlight would turn on. After the bike shut off during my last start, the front headlight won’t turn on now. I did have a look into the starter button module (that sits on the right handle bar), cleaned it and at that point is when the front headlight wouldn’t turn on anymore.

I’m stumped as to what could possibly be happening, any help would be appreciated.

Also I’m very new to project bikes and this is my first one, if you do any explanations please provide me placement of objects or modules and where it might be by.

Hi y’all, so I bought this 96 Honda Shadow VT1100C2 as a project bike. When I originally got this bike and had ordered the new battery, the bike turned on fine minus being able to start (found out it was an airbox issue and have since replaced).

This was about 6 months ago, but when I went to start it today plugging both ends into the positive and negative terminal on the battery, I’m not even getting lights or anything on. I didn’t put the battery on a trickle charge in that time and let it sit in my garage. My battery reads 12.48v currently and it doesn’t look like the fuse is broken so I’m stumped on why I’m not even getting a light on. Could it be the battery or I don’t have this on right?

Also please don’t comment about the tape, this was from the previous owner and at some point I will need to redo the electrical on this.

(I know the first pic doesn’t show it but when I had the ground and positive connected it didn’t work)

[EDIT] I did the positive to ground and ground to positive tests that some recommended. My ground is getting the same voltage, my positive is getting a varied reading.

[SOLVED] After some digging with the multimeter, found it was the positive having trouble with flow to the rest of the system. Pulled it out and I had a blown fuse, thanks to everyone!

Any help or diagnostics would be appreciated!
