Answer 1

sounds like weak spark,maybe losing sompression whens the last time you changed your piston.does it bog down after its hot?

Answer 2

Sounds like you put some old gas in it.

Answer 3

Try re jetting it I used to have a kx 100 That was doing that  and if that doesnt work take a look at your power reeds and see if one broke becuse that also happened to me on that bike

Answer 4

if you havent replaced the spark plug in a while then it is definately a fouled plug or it could also be a clogged carb
