Well, diagnosing clunks and other vibrations is actually pretty easy. But there are some common issues that go clunk.
Here are you next steps;
Pull the front brake hard and push down and forward on the bars. Clunk? If so, it's the head stem nut. Pretty common to work it's way loose as it's not super tight when all is good. Or, some dirt/grit has gotten to the bearings in there. You will know if it is from the stem nut as the clunk sound will come from high on the bike.
Next is the front brakes. Ensure all bolts are tight and the pads can slide freely on the slides. Sometimes brakes are noisy but properly cleaned and lubed calipers are fairly quiet.
Next would come the forks, stiction (sticking in place) in the forks can clunk if you're low on oil. Any fork oil leak?
Now comes the rear shock and swing arm. Same deal with the rear shock, any stiction and or fluid leaks? The swingarm may just need some cleaning and lube. Just the same as you pushed the front down, hold both brakes and push the rear down hard. Any clunks? If so, check chain, cush, brake caliper bolts, caliper cleanliness + lube and caliper mounting alignment. And make sure to check the upper and lower shock + dog mount bolts.
Also, check motor mount bolts, there are 3 or 4 of them. It's fairly common for one or two to work their way loose.
These are pretty simple machines overall, if you take your time... finding the source of sounds is pretty easy if you divide and conquer. Just don't try to find a sound while riding or with your helmet on. It masks the source bad enough to have you chasing your tail for a minute.
And since it seems you may need some direction on how to find stuff. Do a search, I am sure the repair manual is avail for download somewhere. If not... do yourself a favor and order one. The $35 it costs will pay itself back many times over from what you will save by doing the work yourself. AND.... you will know the work was done to your satisfaction.
Good luck and we are here to help as best we can.
