after fishing around in my parts store - found a dented shell and twisted baffle - both are original kawasaki heavy industries japan items, they were from a 125 1986 silver model..
the shell and baffle have "KH110 made in japan" engraved in them - the baffle has a dead thud sound to it when rung and is quite heavy too, the shell is also quite meaty compared to any local crap and the stinger pipe is wider than usual..
btw called in a friend who is a motorcycle nut and he said that the true jap imported detailing parts had KH110 engraved in them, the engine parts had KH125 on them
