I have a raptor 80 that when I try to start it sparks and has compression but will not fire. The spark seems weak so I think this may be the cause. I used starter fluid and it still would not start. Does this sound like low spark and if so, the CDI or coil pack?
Thanks

 

Mine did the same thing. I put in a new spark plug and problem solved. Give it a try.

 

i did and it did not work
