My man DS1434, (Corey of Pro Tune Suspension in Ohio) from ktmtalk forum, dialed in a 2002 CR250 shock and added a bit of WP love in the correct rate spring! Set up for GNCC as this bike will see everything from tight woods to MX.
A sweet set of 99 CR250 forks were fully reworked to modern spec too, awaiting springs and the short 2 day shipping back to me. This bike should be sweet with modernized legs.
I've been warned the rebound adjuster is super effective so to adjust it in small increments, and the low speed "clicks" are very soft, so pay close attention to feel them. This is a sweet piece of hardware, when Sachs shocks are tuned in they are among the best IMO.
