Man I just did the carrier bearings on my R they were a pain in the arse.
2 in the back, 1 in the front.
I don't have near the tools I used to, but I finally got the other race out. Sharpened my chisel and used it to cut the race, then it practically fell out. Got the new bearings and seals in, axle put back in and finished up. Got the front wheel off as well, got it ready to get the old tire off and the new front max on. Now to get the brakes working, a new chain, seat cover, and get her cleaned up.
No after pics but some pics are better than none!

On the inside of the axle carrier, there were 2 hex screws just past where the bearings/races seat. I didn't see anything on the outside of the carrier though, no clue what they are for. Should have taken a picture.
Actually, if you zoom in on my 2nd pic, you can see them, on the lower left about 3/4" up.

I was more thinking on the pivot bolt that you put the Delrin bushings in. I have a grease fitting on my bike (Honda XL250R with prolink)
Just thinking outside the bun as those needle bearings seem to be an issue.
Well like BKM said, it's more or less the lack of maintaining them that's the problem, especially with no grease fitting that's easily accessible. I think if I were to go back to needle bearings I would definitely put in a grease fitting. Can't ever have enough lube. With the way I ride I beleive the bushings will suit me better.
What I got from that exchange was Taco Bell and Lube. Should work perfectly.
A gun drilled pivot bolt with holes drilled in the proximity of the needle bearings and then holes drilled into the sleeve to supply grease to the needle bearings is the proper setup. A lot of pivot bolts are hollow from the factory so that is one step that can be skipped. You have to also supply the needles with grease or you're only fixing half the problem. A drilled bolt will only grease the bolt and sleeve.

My pivot bolt was definitely not hollow. Unless it's hollow past the threaded portion.
I have a hollow bolt in my 250r, but it may be a 400ex or 450r bolt?
