I bought it like that
My guess, no one probably ever went into them before
Bought the bike on ebay in 2003, had to drive 250miles to pick it up, steering felt a lil notchy so I talked the seller into a couple deals (gave me the bottom end to a CT90 and offered to pay for new bearings)
Drove through probably the worst rain storm ever on the way home. The next day could not even turn the handlebars.
Seller tried backing out from buying new bearings so I threatened him I'd give him negative feedback on ebay. He promptly paypalled me the money.
I ended up having to cut the race in half with a Dremel tool and whacked like hell on em to get it all off, piece by piece. Went over the stem with fine wet dry or emory I forget which, to smooth out all the knicks I put in it using a steel drift ( I did not have a brass one yet), and used some stuff called Tight to make the new race fit a lil better, since I had to remove so much material
I replaced the bearings with those cheap All Balls ones

and filled the entire space around the steering tube with some cheap marine grease
Have not looked at them since
Kinda like my swingarm pivot shaft that everyone said in no way should I ever reuse!

x TWO!!!
