Hey y’all, I’m new to forums because I had some questions and looking for some answers, I have a 2002 Honda 400ex I had the motor rebuilt back in March and it ran great. Didn’t ride it too much but rode it enough to keep it active. Go out one day to start it and it’s having trouble starting, it boggs out and won’t idle properly. I left it alone and come back service it, added some oil cleaned it up and it still had some trouble but I got it hot enough to ride it. Then I come to ride it again and go to start it and the starter just spins, thought battery was low so charged it up and starter still spins, I haven’t took a good look at it to fix it yet, because I don’t know where to start. I was thinking something with starter clutch but I just had it rebuilt and it was put together in tip top shape, or possibly with the CDI, idk if CDI would cause this issue or not, then again I was thinking it was wire harness because it is a 2002 and wire harness is pretty beat up. Any suggestions would help!! Thanks

if starter is spinning , and motor is not ?, then either the starter was/is wired up backwards ?, or, the one-way starter bearing is bad. the c.d.i. has nothing to do with your problem .

Yes starter is wired the correct way I believe because it has ran before that many times before I had this issue

Starter clutch is bad. Push start it and more than likely after it warms up alittle it will start cranking again. That has been my experiance with them. They do it worse when cold. Best way to check if its turning the crank is at the end of the exhaust. You should be getting air pulse back there.
