One bike at a time.
You really need to confirm that you have no leaks FIRST, then carry on with jetting. If you do have a leak, you will just be chasing jetting.
Compression is too high for a stock crank (non welded). After reading your post, I suggest you tear motor down and see whats going on with crank, bearings, port timings, domes cc, bore size.
Now me: I would check for leaks, jet properly, then let the mofo'er rip. If it blows........REBUILD. good luck and welcome.
