ill probably get flamed for being janky, but i wanted external preload adjustment on the 250 forks but didnt want to pay $100 for some bolts. so i turned some bolts from the hardware store on the lathe, then put a hole in the OEM fork caps, threaded them, greased the bits up and viola. preload adjuster.
heres an image of the first one before the bolt was trimmed and capped:
the plan is to turn some new valves then put a hole through the center preload bolt and run an adjustment rod down to the valves to make a single damping adjustment for each fork (like the new cart kits for the 250, each fork will handle a single damping function: rebound or compression. we will see how long that takes me, since i kinda suck at turning.
