Are you talking about the over flow hose? It's open..
Or are you talking about the T where the has pours into the carbs?

Saw this post after I pulled off my carbs  I didn't check the spark plugs, but instead I noticed the carbs were leaking into the Airbox... That's when I pulled the carbs off lol. I have a feeling it's really close to being rideable again. Just a litttttle more work, right? The guidance is awesome so thank you everybody. |

Take a good look at your needles & seats & floats.....Thats were your problem lies. |

So the floats were incorrectly adjusted.. I flipped the carbs on the sides and the levels were at 25 mm. Then I realized the carbs needed to be upside down, so I flipped them and adjusted them.. Although I didn't get a measurement when they were directly upside down.
I popped them back in my bike and I'm having the same noise as before while starting. Although I think it's just a dead battery. I'm gonna go home and charge it right now. Here's a video of me trying to start it:
Now I'm really curious... Will there be a huge difference in performance if the floats are set at 18mm instead of 17mm? Just curious about how sensitive everything is.

18mm should be o.k......Worse case you may still flood but I doubt it.

To clarify... I did adjust the floats as best as I can Haha

I just adjusted the idle screw a little... It started, revved up to 3k, and I adjusted it a little and it died down. |

I noticed this because I saw a small puddle on the ground. |

Just pulled my left plug and there's was a little bit of soot on it, it was also a little wet.

I have my carbs in front of me and I rechecked the float level.. This time, I tipped it to the point where it actuated the needles but didn't push the little tiny pin in. They were at 21mm on each. Using the exact angle I tipped them at, I readjusted them to 17mm-18mm each. It's 9:00 PM here, but I might as well go ahead and pop them in and see how she runs. |

Got home, put my bike back together... And bam. Started right up. Was idling at about 3500. Took it for a ride, and it had a lot of popping.. But it rode with power. I turned it off.. And noticed I forgot to put the hose that goes from the canister above the tank into the Airbox back on. I'm assuming this is part of the problem of revving too high? Can this actually cause that? When I get home from work tomorrow, I'll pop that back on.. If it doesn't get dramatically better, I'll follow the steps to adjust the idle properly. |

When reving & popping sounds like you have a vacuum leak......After putting hose back on check boots on carbs with a little WD-40.....Once you get the bike to idle you will need to adjust the mixture screws...2 1/2 turns out is a good start.

I did exactly what you said. Got the idle to about 1400 I would say. Ran better than ever.. But seriously bogging though. Definitely felt that power though. One major thing I noticed it was smoking like crazy out of the left exhaust. There was also smoking from under the bike on the exhaust. And it smelt kinda foul. Can this be a bad piston ring? A month ago I did a compressions test that read about 90 psi in each cylinder. I stopped at a red light, and it died because of no gas. Tried starting it a couple of times, and the battery died. Jumped it, and now it won't start at all.. Walked it home about three miles. |

Compression is low...Should be at least 130 to 170....Have you done a valve adjustment. ?

Yeah.. I did the valve adjustment. It was double checked by somebody else.

Or would a new motor be better? I found a 2004 ex500 engine with 23,000 miles on it about 30 miles away from me for about 400 flat. |

That may be the way to go.....A easy to check rings.....Add about a teaspoon of engine oil to the cylinder & retake compression test.....If compression comes up the rings/cylinder are worn.....if no change than a head problem.

Remember.....2004 EX 500 is chain drive.....you will need to change rear hub and sprocket to a chain drive unit, or get a rear wheel assembly from a late Vulcan or Ninja...will not match front wheel, tho. Also, will need to change some parts from the 454 engine to the 500 engine to make it run in the 454 chassis. Next time I'm home, I'm gonna try the teaspoon of oil in each cylinder. Although, I was curious so I started making a shopping list. Here's what I have so far: 2004 Ex500 engine- $400.00 1987-2009 Ex500 carburetors- $229.00 2009 Vulcan 500 Swingarm- $40.00 1994 Vulcan 500 rear hub- $50.00 Emgo/other brand air filters: $30.00 Total: Est. $749.00, give or take a little. Could you off the top of my head tell me if that would work? Should I anticipate anything else? I'm willing to turn this bike into a project now that I have another form of transportation and a few mechanic buddies willing to house this/help me swap everything out. Would doing this give it essentially the same power of a late Ex500? How would the ride be compared to stock? |

94 Vulcan 500 is still belt drive. 2002 -2004 Ninja (EX500) carbs are the years to use, and go to bigger main jets, 135 to 140. With the 500 engine, you will have to use the stator, stator cover, and flywheel off the 454 engine. The 500 engine does not have a tach drive, so if you want to keep the tach, you will have to use the 454 cams and valve cover.

Hypothetically, if it is the piston rings, what would I have to buy to Fox them? Or what would a shop charge? Trying to weight the two out.

You would need a set of rings for each piston, and a top end gasket set, and a torque wrench to get the head bolts tightened right, and a manual. I have no idea what a shop would charge, if you could find one that will work on an "older" bike.....most will not.

I think I have the same problem but nothing seems to fix it but I added seafoam.
Made it smoke a little until it hit operating temperature then #1 cylinder's smoke turned black turned it off and can't get it to start now I cleaned the carbs out good and still nothing
