"Singing" is often caused by a too tight chain. Check the slack again.
I have 1-1/4” slack sitting on it
Sounds like too much. Normally 35mm - 45mm with it unloaded. Does depend on the type of bike (street, dirt, etc.), length of chain, etc. As the suspension compresses, the chain gets tighter. If you could compress the suspension until the front sprocket, swing arm pivot and rear axle are all aligned you would only need a few mm of slack as that is the greatest distance between sprockets. What does the owner's manual recommend?
I don’t have a manual for it, it’s a used bike. Yamaha Virago 250 V Twin. It it’s a little fella but it’s surprised me, I was nervous about riding it far on the hwy but some of the guys here told me they’ve either owned one like it or still own one like it and they run them on the hwy at hwy speed all day. So I just removed the aftermarket tachometer and let it go. It’s been very reliable even out of state.
A little research:

So, slack should 1.2 to 1.6 inches. You measure on the lower chain, 1/2 way between the front and rear sprockets. The bike is measured with the bike standing up and not leaning on the side stand, no rider.
I started on a 250 twin (2-smoker) and moved up to a 350 next. Read up on your bike. Ride safe.
Thanks. I just like to sit on it and make sure it's not tight after applying weight to it before riding off. I miss my old shaft driven 1984 Shadow 700. I rode that bike year round to work 3'rd shift for years. I have to stick with something lighter now, the little Virago is best for me at this point. I wasn't sure it'd work out or not but it's proven it'll get me where I want to go just as the Shadow did. Just took a bit of time to get used to hearing it rev on the hwy.
Mate dont mix your measurements 35-45 mm is considerably more than 1 and 1/4 inches. Which is going to be just about right. Otherwise your right in the rest of your post

i am not one to be clean of rear wheel ,but good god man you are seriously in danger with that much oil has migrated tosidewall/tread of tire
get caught in the rain or hit a puddle and you would be like riding on black ice
which is pretty much impossoible so it means you hit the road
clean up that shit for your own safety
It's not as bad as it looks. Most of it is on the left half of the license plate which is mounted top rear fender in stock location. The tread is bone dry. It does no good to clean it, every fill-up it get's a 2 ounce bottle spread around the chain, then off we go. Like I said, I oil the piss out of it, it makes a difference as it's had 1 adjustment in 4100 miles. If you notice, it's barely worn any paint off the sprocket. In my ''local ride from home'' thread you can see we also have to drive through creeks with no bridges on some of our roads. The gravel and dirt pretty much soak up & rub off any oil that finds it's way to the tread. The dust, well it collects on the wheel and spokes.
It’s not as bad as it looks I lean it to the pegs sometimes and I wouldn’t do it if the tread was getting soaked. I had just cleaned the chain with it hanging from a sling letting it run in gear is why it looked as wet as it did. Now it’s back to mostly dust
