I modified a set of Monster S4 Showa forks to use the fork cartridge and valving from some Showa SBK forks (I was told they were from a 999 - they are 53/53 at the triples and have TiN sliders and have GD161 cast into the lower stanchion). In the original S4 fork the spring sits at the bottom of the fork tube around the cartridge with a spacer tube on top. In the SBK forks the spring is much shorter and there is a washer that sits on the top of the cartridge that the spring sits on and then there is a short spacer tube above. When I look at the parts book for the 999 forks, the spring looks like it should be at the bottom around the cartridge. Can anyone tell me what the correct configuration is?
