I'm going a little nuts trying to nail down what's causing this. Any help help or feedback would be so much appreciated.
Once warmed-up, I'll get blue exhaust smoke, and the plug will gets a sooty black coating. I'm assuming it's an oil problem. My gut says rebuilt the top-end, my wallet and watch both scream no.
Bike was a non-runner when purchased. Story goes: was a barn-find from an old man that only rode it occasionally, seller "didn't want to" put time into rebuilding the carb. Odometer is just over 1,200.
First thing I did, was drain the crankcase: thin oil with strong gas smell. After the 1st oil fill, I ran the bike ~5 minutes to warm and circulate that new oil, and then I flushed and filled with new oil a 2nd time. Didn't overfill either time (added 3qts, 2 minutes running, 15 minute rest, and then topped to middle of oil window). New oil filters too. Also replaced the petcock, and a new in-line gas filter. Diaphragm had a hole, so I rebuilt the carb. Float level is 12.5mm (within spec), pilot screw @2.5 turns (spec is 2 7/8), needle clip in 3rd groove (I'm at 1,000ft).
Bike starts easy: slightest press of the starter, and its idling nicely. Once warmed, I got blue smoke. Engine also bogs; will not climb a 10% hill once warmed, but it'll do it when cold (if I'm gentle on the throttle).
I've changed the plug a couple times during this process. Every time, it starts and idles fine...until its warmed-up. Then it's a little more difficult to start, and it smokes once running (and warmed). Bike also tends to die if shaken side-to-side. Only times it didn't die when shaken side-to-side, is when I had the air filter off. Still not sure if the dying is due to an electrical issue or not...haven't traced that one out yet.
Leak-down shows no issues, either warm or cold (even did it with the oil filler cap off...just in-case of a plugged crankcase vent):
I can't tell if the bike is burning oil or not, as the seller left me a little surprise (yea, it drips from the cover ~10x/minute while the engine is running):
I'd expect blue smoke on starting it this was a valve issue...but there's no hint of smoke when the engine is started/ran cold. I'd expect a leak-down to show pressure losses if this was bad rings...but cylinder holds pressure whether hot or cold.
Does this still sound like a top-end rebuild project? Or am I overlooking something?

How do these people survive?
Recently, when I went to McDonald's I saw on the menu that you could have an order of 6, 9 or 12 Chicken McNuggets. I asked for a half dozen nuggets. "We don't have half dozen nuggets," said the teenager at the counter. "You don't?" I replied. "We only have six, nine, or twelve,” as the reply. "So I can't order half dozen nuggets, but I can order six?" "That's right." So I shook my head and ordered six McNuggets
I was checking out at the local Wal-Mart with just a few items and the lady behind me put her things on the belt close to mine. I picked up one of those "dividers" that they keep by the cash register and placed it between our things so they wouldn't get mixed. After the girl had scanned all of my items, she picked up the "divider", looking it all over for the bar code so she could scan it. Not finding the bar code she said to me, "Do you know how much this is?" I said to her "I've changed my mind; I don't think I'll buy that today." She said
"OK” and I paid her for the things and left. She had no clue to what had just happened.
A lady at work was seen putting a credit card into her floppy drive and pulling it out very quickly. When I inquired as to what she was doing, she said she was shopping on the Internet and they kept asking for a credit card number, so she was using the ATM "thingy."
I recently saw a distraught young lady weeping beside her car. "Do you need some help?" I asked. She replied, "I knew I should have replaced the battery to this remote door unlocker. Now I can't get into my car. Do you think they (pointing to a distant convenience store) would have a battery to fit this?" "Hmmm, I dunno. Do you have an alarm, too?" I asked. "No, just this remote thingy," she answered, handing it and the car keys to me. As I took the key and manually unlocked the door, I replied, "Why don't you drive over there and check about the batteries. It's a long walk."
Several years ago, we had an Intern who was none too swift. One day she was typing and turned to a secretary and said, "I'm almost out of typing paper. What do I do?" "Just use copier machine paper," the secretary told her. With that, the intern took her last remaining blank piece of paper, put it on the photocopier and proceeded to make five "blank" copies.
I was in a car dealership a while ago, when a large motor home was towed into the garage. The front of the vehicle was in dire need of repair and the whole thing generally looked like an extra in "Twister." I asked the manager what had happened. He told me that the driver had set the "cruise control" and then went in the back to make a sandwich.
My neighbor works in the operations department in the central office of a large bank. Employees in the field call him when they have problems with their computers. One night he got a call from a woman in one of the branch banks who had this question: "I've got smoke coming from the back of my terminal. Do you guys have a fire downtown?"
Police in Radnor , Pa , interrogated a suspect by placing a metal colander on his head and connecting it with wires to a photocopy machine. The message "He's lying" was placed in the copier, and police pressed the copy button each time they thought the suspect wasn't telling the truth. Believing the "lie detector" was working, the suspect confessed.
A mother calls 911 very worried asking the dispatcher if she needs to take her kid to the emergency room, the kid was eating ants. The dispatcher tells her to give the kid some Benadryl and it should be fine, the mother says, I just gave him some ant killer..... Dispatcher: Rush him in to emergency room!
Life is tough. It's tougher if you're stupid
Working people frequently ask retired people what
they do to make their days interesting.
Well, for example, the other day Gladys and I went
into town and went into a shop. We were only in there for about
5 minutes. When we came out, there was a cop writing out a
parking ticket. We went up to him and said, "Come on man, how about
giving a senior citizen a break? " He ignored us and continued writing
the ticket. I called him a Nazi turd. He glared at me and
started writing another ticket for having worn tires.
So Gladys called him a shithead. He finished the second ticket and put
it on the windshield with the first. Then he started writing a third
ticket. This went on for about 20 minutes. The more we abused him, the
more tickets he wrote.
Personally, we didn't care. We came into town by bus.
We try to have a little fun each day now that we're retired. It's
important at our age.
