Well, I think this was one of the problems... I used a grind stone in the drill press and thinned it...significantly.

how was the outside of the bearing shell? did it looked like the bearing had been extra hot any bluing?

Didn't come out in the photo, but it was almost completely blued. Pretty dark in some places. And it was kinda gall
welded to about a 2 mm wide strip, 3/4 way around race. All back together now.

when i used to have the bike on the rear pit stand you could fill the friction from something,all gone now with new bearings

| | Posted : 22 Sep 2012 - 18:47 Post title : Re: Service your pulley bearing. (Re: DizzE) | | | Finally got it sorted. Everything seems fine. The ABS was wires. I don't know why I thought there was fiber optic.
Probably something I heard. IAC, it seems like it might an ultra sound transducer. Solder back. No faults.
I read all about the wheel adjustment tool, got one and it seems useless. I saw folks looking at the measurements
using the tool. I could never make any sense of it, the measurements were so far off.
So, my technique, for what it's worth.
- On the Right, got the belt tension to what I wanted (real loose)
I can't quite touch the plastic belt guard. It might need to be tighter.
Then I hand set the belt, just pushing it slightly inboard at the bottom and rotated the wheel forward.
I just hand adjusted the Left side, until the belt stayed put, by hand rotation. I can fine tune it more toward the center.
But, it's stable in rotation and not on either edge.
And here is why I started with belt and not the measurements. Look a the difference. This is the stable setting for the belt,
on the stand, in 2ond gear. Need some road testing now. So far so good.

(Re: DizzE) | | | DizzE: Set your belt tension or free play at the belts tightest point as measured in the little slot in the lower belt guard.You want it loose,but not that loose.Mine is set between 1/2 and 3/4 of an inch at its' tightest point.Rememeber,as the belts gets hotter,it WILL CONTRACT,meaning that free play or tension will decrease,plus the belt will move left to right and back as load changes,but if it's too tight OR the cogs are dirty,it will stay on one side and chirp like hell.My belt runs more to the left and moves side to side dpending on load and turns.When ya get it right,you'll notice the sides of the belt are grey in color verses black from making too much contact with the edges of that rear cog.

But, just got it backed out into the driveway and the clutch lifter gear rolled off the end of the rack. No clutch IN.
Damn.
I will pull the side cover, reset the lifter and make sure I have rolled on enough tension. Still need the road tests on the belt.
We'll see.
And Mat, early days, I may have pranged my swing arm when it roll onto the floor.

Well, now with another 2000 mi, I would be thrilled with these Adjusters. Except one problem.
I never think about it! After all that, it was the bearing that was making the noise.
It does, somehow, seem smoother, also. And I'm not grinding the outside edge of the belt.
However, I give the needle bearing removal task, 3 out of 5 in difficulty. Meaning
if you don't know, have low confidence, no equipment for grinding it out, etc, don't think this
is DIY doable. But, it is easy enough to take it apart, remove the pulley, etc.
Then take the axle hub to a machine shop to have the needle bearing removed. It is easy after
that.
2 out of 5 for that route.  (need the torque wrench)
Oh, I did try it, super-loose. More loose than bblupo would suggest. Don't know how to say it
but it just seemed weird. Subtleties of the power transfer, I imagine. Now I run loose.
But, my definition is the collapse the gap between the belt top/bottom, 1/2 way.
Before it was all the way to touch the other side of the belt.

After reading what was in the Service Manual I was a little confused so I had a PM discussion with Matt and I did it a little differently.
Matt  with a bit of editorial cutting and shutting of other posts and the original post I have depicted what I did to remove the inner roller bearing to get access to the inner needle roller bearing for inspecting cleaning and repacking as I found it virtually impossible to get a needle punch past the needle roller inner race and onto the roller bearing inner race and I did not have a bearing remover.
This is the 'inner' bearing spacer. Notice signs of rusting.+ you can see the inner race of the outer needle roller bearing against the roller bearing inner race.First remove this circlip.
This picture depicts the Needle Roller Bearing and Inner race which actually sits up against the Roller Bearing inner race.
This photo shows the inner race of the needle roller protruding level with the drive pully outer seal + the Stepped Socket and Extension to be used as a drift to remove the inner roller bearing via the inner needle roller race.This is so you dont damage the inner needle roller bearing race.
Depicting the Stepped Scoket & Extension to be used as a drift tool.
 
The 'inner'sealed bearing removed which allows the removal of the needle roller inner bearing race so that you can clean and inspect the bearing.

Hopefully this might make it a bit clearer and simpler for someone attempting this task.+ My bearing was Ok and My bike was built in May 2011 so it has the later model needle roller bearing.
