I have a 2001 660 that I can’t get spark out of I have replaced the cdi box, coil, spark plug and still nothing what could the problem be??

 

Power coil or trigger coil on stator. Other possibility is wiring. Never fails to amaze me why people buy new CDIs instead of doing the checks first. You can blow a new CDI if you don't make sure the earth lead to it is correct, and testing will point you towards what is actually wrong. The workshop manual will have all the correct tests for your model, but some idea can be got from the "help diagnose stator" sticky on the Chinese engine problems page of this forum.
