I have a 05 750 brute force and previous owner converted to fuel injection long ago. Its been running good and one day i lost spark . I put a new cdi on it and this didnt fix the problem. i replaced the ecm and this didnt fix it. It has new plugs in it. I went after the stator and i hadnt drained the oil, but when i pulled the stator cover off... per service manual, much oil came running out of it. Is this normal?
