different stators causing misfire?

on my speedfight im meant to have just a 3 wire stator that has 8 coils. When i swapped my bottom end it came with a 4 wire stator with 6 coils from a very early speedfight. Could this be causing my ped to misfire, as when running it goes pop pop pop, blows air out the exhaust and dies. Thanks to anyone who can help

 

Depends, are they compatible? How did you connect 4 wires into 3 plugs?

 

i didnt, 3 wires are plugged in but one isnt

 

I think that you connected them by colors. Good way to check their target by comparing where they go on both coils.
For me it sounds like shaft position sensor fault. Maybe bell don't fit to this coil?

 

its a whole speedfight 1 bottom end and the engine wiring loom is different to the speedfight 2

 

im gonna try that

 

im going to order a speedy 2 stator off ebay, but will there be a difference between a 50cc stator and a 100cc stator? they look exactly the same

 

there will be difference the 100cc stator may be a little bit bigger just buy the right one for your bike then it wont keep givin up on you lol
