Long time lurker and haven't posted in a while. I have a blue KS frame that a buddy gave me years ago. Its just the frame and matching KS guard. I've since found a matching radiant blue fork and extended/grafted on a longer steer tube. The hard part was trying to find the fenders. Due to the larger geometry of the frame the fender mounting hole at the seat stay bridge aligns at a slightly different position radially on the fender (if that makes sense). Its like 3/8-1/2" off from a reg size middleweight fender.
The black KS above with the chrome fenders reminded me of this... quirky fun fact; Twinn (Tandem) middleweight fenders have the same hole position and fit a KS frame perfectly.
