Speedo drive on the front wheel? When they run out of grease they squeal something rotten.
Front fork seals ? Do you get the same when breaking ?Are we talking hard acceleration then cruise/throttle off.....gentle acceleration then cruise/throttle off. Acceleration from standstill or acceleration from any given speed ? Any particular gear ?
Parrot attached to the handlebars?
Knackered wheel bearing/s?Speedo drive as mentioned.What about your lid? Vent open/loose and causing high pitched noise?Chris
If the wheel is not straight and the chain a bit dry then that could cause the noise.With the bike on the centre stand, spinning the wheel will tell you if it's aligned correctly or not. The chain should quietly purr when it's right, but if it's not straight then you'll hear all sorts of noises.When adjusting the chain slack don't forget to slacken the brake caliper bar, and take your time nipping up either side a tiny bit at a time then spinning the wheel to hear if it's okay.You want roughly around 35mm of play at the lower middle part of the chain, or a quicker and easier way is pushing the front of the lower chain upwards with your finger and it should just touch the plastic chain guide. Having it too tight is just as bad as having it too loose, so get it right then you won't need to adjust it again for ages.I've started using a paint brush with engine oil to lubricate my chain now, instead of spray lube which i used for decades, and the chain is in better condition than ever. Plus it doesn't clog up any more, it repels dirt, and the oil effectively gets into every link when applied when the chain is warm after a run plus only takes a maximum 2 minutes to apply. I have newspaper down in my garage to catch any drips, and any other excess gets flung off next time i ride it.

Side of trye - undertray -underdarrsi As Dude says you can "carefully" spin the back wheel on the centre stand and it will just fling off in a straight line behind the bike (use newspaper), or a lot of people will run a decent rag round the chain after oiling (one that doesn't fall apart) to mop up any excess oil.Also, as he mentions, you just use common sense about how often to oil it. It does last longer than you'd imagine but if you've just done a motorway run in a storm then it would make sense to give it a bit of aftercare, but i don't think that will apply too much with you. You will get an oily rear sprocket though, but that really doesn't bother me at all.

I am nearing a new chain and sprocket set although its not badly worn the chain does have a tight spot that I can not free up and I can feel it when riding. I have always used chain wax but my riding is is all dry - so that's dust and grit that sticks to the wax. So I think when I fit new I am going to give engine oil a go and see how the fling goes. But cause I like my bike clean I may end up under lubing the chain. Sorry for the post shieldr

The chain shouldn't really be hanging off after only 2k. Either you're not oiling it enough and it wearing faster than it should or there might be a bit of play in your wheel bearings or swingarm bearings. Most likely is you're not oiling it enough but I'd check the wheel and swingarm bearings to be sure. How often you have to oil it depends on the lube you're using and the weather. If you're brushing on gear oil probably once a week/every other petrol fill up is enough or if it's very wet maybe do it every fill up. If you're using spray on lube you can push that further but you should still be doing it regularly. That's just my thoughts on it but it's definitely true that the same chain can last 50,000 miles or 5,000 miles, it all depends on how well you look after it.
I had squealing that matches your description. At first I thought it was a worn chain too, but it turned out to be a worn chain and a knackered sprocket carrier bearing.
