Hi hoping someone out there can help me. i am replacing the exhaust clamp which has rusted. It is the clamp connecting the exhaust coming from the engine to the bit which joins with the Y section. Sorry for the stupid description. Prob is - i have taken off most of the old clamp - skinned knuckles n all - but there is one piece left. It looks to have a screw innit or at least a rounded bit still attaching itself to the exhaust. Dont know whither just to take a hammer n screwdriver to it and chisel it off - or what. Can anyone help - this is one hacked off bird trying to do something soo easy, but its freaking me out. SV650S K2 silver dream machine
