Often a sudden change in jetting means a air leak.
Have you done a leakdown test?
im gonna go ahead here and ask a really stupid question but how are leakdown test done?

not a stupid question...it just shows you're willing to learn....

sounds like the float valve is worn and/or the float valve seat...I would try a new OEM float valve 1st, don't buy the aftermarket trash.

as long as it doesn't start leaking out the overflow tubes for no apparent reason, then you should be good to go.

i asked my dad about the oil seal leak, he has seen alot of coolant and oil leak smoke in his time, and suggested that it would not smoke if i just let the bike warm up proberly. so i did, and gues what barley any smoke and the bike ran fine, not perfect i probably have some jetting to do, but for the first time since i bought the bike i was able to experience the true 500 two stroke power.(...was scary) ill still post the video of how the bike runs prior to proper warm up incase i have missed something https://www.youtube.com/watch?v=LfoSwTUixQA&feature=youtu.be

other then that, the thing is a BEAST i shall call him...Rudy!

everyone has their own procedure....I myself like to keep a very steady idle at about 2500 RPM's, then when I can't hold my hand on the side of the cylinder for more than 2-3 seconds, I know it's warmed up enough to head out my trail at an easy pace, which is about a 90 second ride until I get out into the powerlines....by that time, it's warmed up enough to start rolling the throttle back, all the way :-o
