dug the sprocket carrier out of the parts bin with all intentions of just gunking it down and wafting with a rattle can, it's a piece you won't even see, after i cleaned off the grease and grit i could see that, at sometime in the bikes history, the chain had jumped the sprockets and twatted the carrier, i set to with some 400 grit wet and dry paper and cleaned up the damage, stuck it in the lathe and machined up the front surface and drilled out some 10mm holes between the strengthening webs in the casting, costs nothing and weighs even less......
