Removing steering stem on 919?

Has anyone removed the steering stem on the 919? My manual says I need a special socket for this. Do you guys know how much one of those sockets run? I have bad bearing in my stem and plan to replace them myself instead of the dealership doing it.

How did you determine the bearings are bad?

When I turn the bars (almost said wheel ) something pops-kinda grinds sometimes. When I go over rough surfaces it sounds like something in there is gonna fall off. nothing feels loose. All bolts in the front end are tight.

This just seemed like the right thing to do- throw parts at it.

I've removed the triple from my 919. It's quite easy. I have the service manual, but I didn't really need that. Prop up the front of the bike and get the front of the wheel off the ground (I used a jack and some blocks under the headers, they are strong enough. Keep in mind I had a rear stand on the back so the bike wouldn't tip) and:

1) remove the handlebars
2) removed the wheel
3) remove the fork legs
4) remove the top triple, there is a castle nut under the top triple, you can just use a flathead screwdriver and hammer to gently loosen it if you don't have the right tool.

Everything else is pretty self expalnatory. If you don't have the service manual I recommend taking notes on which order and orientaion the nuts, bearings and races go back into the steering head, that can get a little tricky. Taking pictures might help too.

Good luck.

Removal is fairly easy. The nut is really required if you want to be able to torque it when you reinstall. There is a how to somewhere on the net of a guy who made one of these using a socket and welding the "fingers" on it.

Before you tear into your bike, you might want to check out the plugs behind the headlight. I read somewhere that the plugs will hit against the back of the headlight when slowing down and going over bumps (obviously). I thought I had bearings worn out on the front of mine too, and I had just bought it new! Turns out a couple of the bundles were hitting the headlight, just like I had read. I'm not sure how many miles you have on the bike, but if it's not too many, you might want to look into that.

To fix the problem, I wrapped some electrical tape around the plugs. Stops the plastic on bulb crime.
