Hey there!
Just redid my carbs on an old valk your that was sitting in a pole barn for 5 years barely ran.
On my way to work this morning smelled oil, and looking at the bottom of the bike, two or three cyl. On the left side are leaking oil from where the exhaughst pipe goes into the engine. Heavy amount of oil in pipes on left side.
Valves? It's just the valve right..? Oh lord... I'm going to have AAA pick it up but looking for a likely problem so I know if it has to go to a shop or if I coild do it myself.
Thanks!

First thing I would check is oil level. Sounds to me like fuel leaked in through the cylinders and past the rings into engine. To much oil and will leek back into cylinders and out exhaust. There usually isn’t much that goes wrong with the engine itself.

Might be gas leaking in, picking up carbon from the cylinder and leaking past the exhaust valve and thought the peep hole in the muffler. It will look like oil be careful you don’t hydro lock. Check your oil level if it’s higher than normal you got gas leaking past the rings if not remove the spark plugs and look for gas in the cylinders

Checked oil level on break, is above normal level. "oil" that was on pipes appears to have evaporated except for #1(FL) pipe/cylinder... Will have it towed home this evening. Hopefully just a stuck bowl or something, but no clue.
Worked fine last night...

... But just a thought, if I was running the bike pretty heavy, how come it still got gas everywhere? Wouldn't the cylinder be able to burn it up?
Why did I keep smelling oil when I was stopped or catching the wind just right? What should I check besides the carb?

Sounds like petcock failure and float issues thus a candidate for hydrolock. I wouldn't try to start it until this issues are checked and/or fixed. You can rebuild your stock petcock or replace with manual Pingel petcock which is a revision to avoid the fuel leaking into bad carb floats etc. Been using manual petcocks all my life except on my 00' ZR7 Kawasaki. The original owner already upgraded mine to Pingle already. Don't forget change the oil and filter before running again. |

#1 is FR(front right). Cylinder #'s on the right front to back; 1-3-5, on the left front to back; 2-4-6
I agree with the gas in oil analysis, something isn't working right in the carbs you just reworked and flooding the cylinders with fuel. Definitely don't run it until you figure it out.

Take a breath , stand back and use reasoning. D O N O T panic. Approach it one item at a time and do not assume you did the job correctly. Poop occurs. Every one will make a mistake sometime.

My bad. Been a, while since I looked at the service manual. #2 cylinder. Pet rooster works fine and was rebuilt about a month ago as, suggested via forum linked kit. However there's enough gas in a bowl full (or running engine) to pour into there, I suppose.

If you have fuel in a cylinder your petcock is not working fine. It’s malfunctioning. |

If you have fuel in a cylinder your petcock is not working fine. It’s malfunctioning. Yes, especially if it's enough to raise the oil level. Agrady1995, the petcock rebuild kit only deals with the vacuum side of the valve. If the valve is letting fuel get by when it's in the OFF position, there's no kit to fix this; buy a new valve. |

FYI
The oil level is checked with the bike stand straight upright, not on the stand.
Like mentioned, calm down and figure it out, don't start jumping to conclusions. Do what you're doing now, ask advise.
Learn what a hydro lock is, and what it sounds like (clunk), and don't hit your starter a second time if you hear it.
As for the smell of oil, it takes a while or a very hot motor to burn it off completely, so you might be smelling it for a while.
You also mentioned pipes. But my first thought while reading was the coffee staining from the intake tubes. O-ring seals leaking.

Goodmorning all. The bike is in the garage today, waiting on me to put the head unit back on my girlfriends rebel 250 this afternoon. The petcock does work okay, however if the vacuum is applied to the line attached to the back of it, then it will release fuel into the carbs. As the tube is attached to a carb, and the bike was running, AND the fact that I tested it working a week ago, I am reasonably certain the petcock is fine, and the gas-in-oil is from the drive to work.
Additionally, I thought it was common knowledge to check oil level on flat and level surface.... But thanks, yes I do stand my bike up to check that. I have no problem balancing it and checking oil.
Black and red is still OK, so I guess those carbs are still holding up to me working on them (LOL). I'll update this when I have managed to find the issue.

Even if the petcock never shuts off, fuel will not get past the carbs unless the float valve(s) are leaking and not shutting off the fuel flow.

This is true. But Valkyrie engines won’t hydrolock while running. This means it locked after shut down. This means bad needle valves/floats and bad petcock if it’s a stocker. |

Took Carbs Apart Yesterday (FINALLY). Had help from a neighbor to seat everything back, so round-trip repair was about 2 hours. The 35S Jet came out of its' hole, and I put it back in TIGHT. Broke it. Had a bag of back ups. Put it in TIGHT (almost broke it)....
Runs ACES now!
Thanks all for dealing with my panic.
