Hi guys,
I CAN NOT figure this out. I had my frame painted andI have my 400ex completley put back together. I never tourched the engine as far as tinkering with it, that is al stock. I hit the sarter button and you can hear the starter kick on, but nothing inside the engine takes place? I took the cover off the starter gears, and that is all working, but it just isn't engaging somehwere in the engine like it should? Any comments? Anything will help, thanks a ton!!

mine did the same thing last year i had to take it to the shop. it ended up being a baring they said that they had never seen one go bad before but they put a new one in and it started right up

i beleive the baring was inside the motor case but im not positive because i had the shop replace it. it cost $70 for the new part and labor. mine went all at once it didnt get bad and then go it was just like one day i went out to start it and nothing happed the starter just spun and didnt engage

the baring wasnt exspensive it was the labor that brought the price up

where is that bearing at? i have been told it is the sprag clutch that can cause this. this is mounted on the back of the flywheel for you that want to know its location.

yep the one way bearing on the back off the flywheel. it`s called the starter clutch. I had to replace a couple, one on mine and on some friends quads

Mustang400EX, If your starter circuit operated properly before your paint job, you might try looking into the ground circuit for excessive voltage drop. If you dont have a good meter, I would suggest removing all the ground cables and making sure you dont have paint under your ground cables, these areas need to be bare metal to ensure a good ground path....Tech23
