There is a heatsheild on an NB over the muffler that can generate a fair point of noise I put some silicon on it then another layer of sheet metal Probably could have made it lighter than I did but it was effective The foam in the two tunnels to the left and right of the fuel tanks was effective I did the majority of the tub with 1# mass loaded vinyl not that effective There is a website called Sound deadener showdown that has a lot of good info Can someone tell me how to locate the two other tunnels that were mentioned? (Not the ones to the left and right of the fuel tank)
