The "black tuning blob" - is that what that is? I thought so myself, but then I experimented with removing it and felt/heard no difference. That side of the bolt is right next to the exhaust pipe - would it be possible the 'blob' is there for heat-sink purposes of some kind? I wouldn't think so, but... If it's not there maybe the bolt and aluminum boss might get too hot, make the rubber brittle eventually? With it there, it absorbs heat and dissipates it, kind of like a buffer, so that the other stuff doesn't get as hot?? Again, I doubt it, but... I think Honda used that huge, heavy metal bracket by the VTEC/'spool' valve for heat sink purposes (the spool valve or whatever gets pretty hot)...I was tempted to make a steel sleeve with 2 short mounting bolts and reduce the weight of the black tuning blob....
