Was Gobsmacked when i took the back wheel out of my Gf swing arm, never noticed at first until started to clean and check the sprocket and bearing .....WHOOOOOAA !!! surely it couldnt be him could it ? someone had welded up the short part of axle thats in the sprocket , looks like it had been cracked and welded in 2 places then ground off and refitted . Scary or what ?
