magoo, not that i really know what makes for 'cartridge' forks, but i do know my '83 forks had different internals from my '86 internals. the '83 didn't have the damper rod (or whatever you call it) that bolts to the underneath of the fork cap like on the '86, which i woulda thought was part of the 'cartridge' mechanism. plus the '83 only had holes in the damper rod for damping and the '86 has.....some ovver fing. so what gives then?
