tbh your right i have that problem with one of my bikes it sparks when the plugs out of the head but when you put it in it dont start or dont even attemp to start lol

It's a sign of weak spark,
Usually it means a coil is on it way out,
Or that your using a irk,
If you have got your heart set on a irk then buy a kitaco one

i new it was somthing to do with your valves and your cylinder is most proberly scrathed because the bit what has chipped of the valve has gone into the bore and scrathed it up and yess it will i think most pit bike engines will fit on it bro
