Dale, Most unusual, as I have never seen different valving per leg on these or any forks that have both compression and rebound in both tubes. The '87 forks were very good with stock valving. The 125 forks will have lighter valving and springs due to the bike being lighter than the 250. There should be a sticker on the...

I bought a set of the steel tubes and inner cartridges from Sudco in '86 and started using them right away on my '86 Yamaha YZ490 for D37 Desert Racing.
