I've never seen a Talon with a leg out, based on seeing about 20-30 at the tip and working on a few over the past few years.
Biggest thing is no oil, followed by back wheels falling off, then buggered pull starts. I have heard they hammer down their valve seats and lose compression, but its difficult to tell this from no oil damage.
Some just need a carby clean - just like many 4 strokes thrown out
