Thanks to a girl at school knocking over my bike I recently replaced a scratched up stator cover.


The manual for my 2002 F4i calls it an alternator. I'll call it a stator since it is shorter and many people refer to it that way.


1. Remove left fairing.

2. Drain the oil, try not to drop you filter in to the pan and splash oil everywhere like I did.


3. For an F4i, unclip the idle adjuster and push it out of the way.


4. Remove the nine cover bolts. 8mm socket.

5. Gently pull the cover off. Don't use force. You might have to tap it a bit with the heel of your hand to break the seal. You can use the three tabs to actually get a hold on the cover to pull. Work all the way around the cover to make sure that the seal is broken all the way around. The stator is magnetically attracted to the flywheel so you have to use a bit of force when you pull the cover. However there is a small dowel still holding the cover in place so you have to pull absolutely straight out. If it sticks just back up and start again. It takes just the right "touch."


6. I tied the cover to the frame so that it could hang without putting any pressure on the stator wire.


7. Gently tug on the rubber grommet that contains the stator wires (blue arrow) to break it through the old gasket, remove the wire clip bolt and wire clip (red circle, red arrow), then remove the four stator bolts (black circle).


8. If you are reusing your cover you need to clean the old gasket from the cover, brake cleaner, or denatured alcohol works for this. Otherwise just set it aside like I did and hang the stator somewhere.


9. Remove the dowel and clean the old sealant from the points where the crankcase halves come together, I used denatured alcohol and my thumbnail. Save the dowel unless you purchased a new one like I did.


10. From here on out the last part kind of needs to flow into one big step all at once. I was really wishing for a third hand for part of this. Add sealant on the crankcase at the two points that you cleaned it off of earlier, it only takes a bit, I used Blue RTV.





More to come, have to go.

I have to replace the crankcase cover on my 919. That's essentially the right side of this same set of steps, and less involved, from what I can see. I think its just 3 screws and a gasket, and try to recover the oil I lose in the process?

Funny, I actually forgot about it. It's only half done, I ran out of time and had to go to class when I was writing it. I'll have to find some free time and get the directions for putting it back together finished.
