And pull the spark plugs and turn it over to see if cylinders are drastically flooded.
Won the bid, not sure if I will be awarded the 1979 YAMAHA XS1100

I’m guessing that the jets are plugged almost solid. The bowl vent is a much larger opening and located up high in the bowl. I think Gon has already had it turning over. Small risk of a cylinder being full of gas.

Pulled the carbs. Have to say thankful for a youtube video from down under on how to pull the carbs. The airbox is a real challenge, and normal think would point to taking numerous screws out of the airbox. These screws don't go back in easy. The youtuber does a solid job on what to do.
After pulling the carbs, two were still full of fuel. Both the carbs full of fuel are a team, and they get their fuel from the same petcock (this bike has two petcocks feeding two carbs per petcock). Of the two carbs with fuel, one of the floats barely floats. Pictures tell some of the story. The last picture is a close up of the float that was not easy to move up or down.

Here is a video of measuring the float bowl heights on a xs1100 carb, what is interesting is the reason for the height inspection was fuel flowing out of the air intake box.....
Mr GON are you still working on this, give up, or just move to the back burner?
Not in my shop!

Update- I have all the carb parts. I also have the front brake master cylinder rebuild kit. I have numerous projects going on at this time, the bike has taken a back seat. If the weather was nicer, the priority on the bike would be higher. Not for riding, but I just don't enjoy working in a cold, dark, damp garage. Most of my time spent over the last 30 days has been on the 2002 F350, from installing a 2015 center console, upholstering the front seats, and completing the front end conversion from a 1999-2004 to a 2005-2007 front end.
Of note- I have another auction bike I am waiting for to purchase. I am hoping it doesn't come to auction anytime soon, as the bike is a long ride from me across a tough winter interstate. If I win this bike and think that is likely, this will be a donor bike for parts.

Thanks for the update and good luck on the rebuild!
Something that can get overlooked on a bike that old, is to make sure the intake manifold boots and the boots between the carbs and the airfilter box have no cracks. If they do you could get a lean condition in one or more cylinders, with unhappy results.

Picked up a parts XS 1100 at auction last week. 1981, looks like it was in a accident. Progressive was the Seller. Bike is located in Lennox, SD- so I won't be able to get the bike any earlier than the end of March as I am OCONUS.
My bid of $25 won the bike, with fees a little under $200. The cost to get the bike will be large. But rather have this project than watch TV.
