I have a 99 big bear that will not fire, new plug new coil new stator and pick up cdi is all that's left. Put a used cdi off a running 96 big bear on and bike won't turn over, old cdi will turn over but no fire. Is there a wiring difference, if so how can I figure it out? Need help please urgent it's driving me nuts

 

Check part numbers for both years. go to partzilla.com and look them up thatll answer the cdi question. Do you have spark?
