#2 cylinder (From the left) getting no fuel?

Sounds like you've got a lot of learning ahead of you. Most here would recommend that you do all the maintenance before hand. Make sure the valves are adjusted, carbs completely stripped and dipped, change all your fluids and verify the electrical/charging system is working properly. NEVER depend on the PO's information to be accurate. There sole purpose is the dump their abandoned project on any unsuspecting victim. Most here would advocate getting it running right in stock trim before starting on the modifications. It's much more predictable and straight forward when trying to troubleshoot issues. From reading your posts it seems like the petcock is probably shot. Don't try to rebuild it. The success rate is very poor and, in most cases, the stock replacement is still available.

Don't try to run the bike till you've done the basic maintenance or you risk much damage. These bike will be very dependable as long as you do what's needed. One of the big problems encountered is a lack of valve adjustment. The bikes tend to tighten the valve gap over time. If not checked and adjusted, the result will be burnt valves and a major tare down. The second biggest issue with these bikes is electrical system related. The charging system depends on a functioning stator and Rectifier/Regulator. R/R for short. If you modify the electrical system and make the lighting system "more efficient", you WILL destroy the stator or the R/R unless you change the R/R for a series unit first. One of the many reasons we usually recommend starting stock and them modding.

Glad to hear that we helped a bit. What concerns me now is your gas valve. Your crankcase was full of gas, there is a reason, and it probably is your gas valve leaking. Either through the vacuum line into #2 carb or the O ring seal is toast. If the condition is not fixed you end up with gas in the oil again, not a good thing.

Right, I definitely agree we can't depend on the P/O's information. As far as I can tell, everything is stock except the signals, and the "digital ignition" system he said he put in.. I've ordered those O-rings, and once I get them I will be taking it apart and doing a good cleaning on those carbs.
Now for the petcock, you're saying the gas dripping out from the crankcase breather hose is from the petcock being bad? I guess I misunderstood before :\ If that is correct, I will get a new one. The one's I've seen are around $45, and will take a week or so to get. Either way, I think I'm going to replace it. I definitely don't want fuel in with the oil, especially after I just changed it lol
As for the led signals front and back.. I would prefer stock of course, that's just what the P/O put on there.. or tried too..
The charging system, he said is a digital ignition system. So I'm not sure if this is an upgrade or not. I have to read more about it, and see exactly what it is.
As for the valve adjustment, I will look in the forums here and find the procedure. Do you recommend doing this every xxxxxx miles?

Don't confuse the ignition system with the charging system. Two completely different systems. If he changed out the ignition system with a Dyna-S, then it is an upgrade.

Do the valves now and then every 3000 miles.

I just looked and I had a screenshot of his ad for sale.. It is a Dynatec digital ignition he says..? Ill definitely be checking those valves, thank you!
