I have a 2001 blaster 200 that I bored 60 over. Its ran like it had a vacuum leak. But while riding it started shooting sparks out of the exhuast. So I replaced all the seals to get rid of the vacuum leak. Now when you try to crank it over the piston sometimes moves and sometimes doesnt move at all. It has some compression. Enough to run. I'm sure it's due for a new top end. But y will the piston only times move?
 
you surely mean while kicking it over it sometimes doesn't catch and turn the engine over ?
look into the kicker mechanism action and spring placement, replace with good used unit if broken

No my kick starter is broken and I haven't got to replacing it....when I try to bump start it. Sometimes when I turn the back tires the piston does not move
 
it either moves or it doesn't, there is no sometimes.
unless it's in neutral or your clutch is slipping so badly, those times your saying it doesn't move ?

The clutch would be the only thing that I can think of...I've never messed with it much tho. I'll check the clutch...if it's not that then what else could it be? I'm mind flipped about it
