The coating is worn because there wasn't enough oil in them OR, one or both tubes are bent.
Thay are all 33mm tubes 200X or 250SX.
I think I read "lathe?" - Buy the 200X bushings and trim them to fit. I do not see them for sale OEM?? Weird....
I'd buy 85/86/87 200X bushings if your teflon is gone.
You can also upgrade to a 200X front end very easily; All you need is a steering stop, they slide right in your top steel. lower aluminum - fork clamps....
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
