Guys, IDK if you're aware but if you use 83/84 250R damping rods in the 85/86 350X, it is very similar to the "terry Kit" available back in the day. It raises or lowers oil hole heights as well as the diameter.
It's the cheapest upgrade for your buck and you can rebuild your forks at this time.
It improves fork action with damping.
These are in CA and 60$ shipped, if I had a 350X in need, they'd be mine...
