Wink roller bearing OUCH!

Yes... I'm starting to think Trans related bearing. I'll pull things apart on the weekend and check the clutch drum first. I suspect the shifter shaft for the size of the bearing.
As I've only seen 4 bearings thus far...I think I'll use a strong magnet and hope I can move 'em out the drain plug hole. This is wishful thinking that those bearings are in the crankcase pan!
Only small metal fragments were found on the screens, but no large particles or pins.
The hunt will go on!
Thanks for all who have pitched in so far.

If you look close, you can see one of the shift shaft needle bearings.

As for riding it like that, imagine what could happen if one of those rollers found it's way into the scavenge oil pump, stopping the rotors and shearing the drive pin in there. No oil pressure usually means a quick death for the plain bearings that support the crank. Or how about what would happen if it found it's way into the trans, between gears? It could lock the trans, causing a sever and drastic loss of control as the back wheel locks up at speed.

Park it until you fix it. Sorry, but it looks like you're splitting cases. Look at the bright side though- if I did it in a redneck's (oops-I mean inmate's) garage in Alabama (Hi Scott! ), how hard can it be?

Those bearings are tiny. Not from a main bearing in the tranny or engine. They are about the size of the needles for the bearing on the RH end of the shift drum. Too small for the locating pins on the end of the shift drum.

This debris can't get into the oil pumps because of the two screens on the pump intakes.

I'd pull the RH engine cover first.

the shift drum bearings are ball not roller

I think #23 is what you're dealing with:



it's a two-row needle bearing, and the race is thin as in your photograph. As it's an "04 she's had plenty of miles to wear that thing out, and the clutches are known for being tricky on the LC8's

put her on the sidestand and pull the outer cover off the clutch and start there- no oil will drain out, even if you have to take the RH engine cover off to get futher into the clutch (and to start fishing the rest of the bearing out! )

Don't run her until you figure it out... but I'll bet you that dime in the picture that's your part!

My bet is that it's part #23 as well.

I found the same needle bearings in one of my oil changes on my 520. Problem was, I changed fluids on all 3 of my bikes that day. Took a week to find the same schematic for the whereabouts of a needle bearing in a KTM motor, I was told that is the only one in there or at least in my 520. I did ride the bike shortly after that and it seemed fine - only a very short mile or so - and it has been parked ever since. Motor is coming out very soon, it needed a good going thru anyways

Sorry your in the same boat (Bust Out Another Thousand)

Looking through the manual, did a search for needle bearing.

Idler gear on the counter shaft.

Reduction gear off the flywheel, magneto.

Timing gear, (too big to be one in photo)

Clutch, as shown too big to be one in photo.

Wicked Thanks Charlie...

I looked thru my parts book that came with my bike the first time around, and believe it or not, there are quite a few roller bearings in the 950 motor.
The problem was mentally sorting out which one 'fits' the look and description of what I had in hand...
Thanks for your reply.

Here's a unique concept- TAKE THE BLOODY THING APART.

Much easier to determine which bearing has let go when it's disassembled.

That looks like a closest match, if you look at this photo by Steverino:



But then again maybe not.. Needles you pulled out are really short.
