OK, tonight I took mine apart to grease, It did still have a light coat over everything, but I am still glad I took it apart to check. The nut on the top clamp is a 30mm nut. The top clamp has KX125 cast on the underside. What's up with that? For the locknut, I used a screwdriver and a hammer, one good tap and it came right loose. I tightened it with the same appropriate tap in the opposite dirrection. I use valvoline full senthetic grease.
That's about all the input i have for now. Do I tighten the top clamp down after I get the forks clamped in? If not how do I get them lined up? After I get my forks, I'll take the rear linkage apart.
