I rebuilt my rear shock for my WR250 1991. The Yamaha manual does not show disassembly or reassembly of that rear shock. The manual suggests it is not rebuildable. I found this rear head seal on eBay and used it. https://www.ebay.com/itm/314753602243?epid=4038191638&hash=item4948c6d2… I purchased Yamaha branded suspension oil. I rebuilt it exactly as I would any piggybacked rear shock. Topping off through the compression adjuster and than sealing it up there. I should have topped off to that screw at the top vs the adjuster. That’s how I would do it again.

Luckily Japanese engineer did not change the triple clamp axle in 30 years, so a kit of triple clamp from 2016 yz is fully compatible with the 1991 chassis. A 1 mm...

4/8/2023 1:55am Thanks, Right now the hardest things to find to me are the standard muffler (everything I find is cut or in very bad conditions) and the radiator louvers as you said. Luckily I find these guys from france making a 3D printed replica. It is expensive but I will buy soon https://m46-parts.com/en/yamaha/261-1990-1992-yamaha-yz-250-radiator-lo…
