I agree that the bike is quieter with 10/30 vs. 10/40 from my direct experience. On my first change the shop was out of 10/30 so I put in 10/40. It was noisier so I dumped it for the right weight quickly
Having said that, I cannot believe that terrible hammering noise coming from your bike is due to a minor oil viscosity difference. I sure hope I am wrong and the change fixes it.
BTW: It sucks your dealer service people are lying buffoons. I would contact Honda USA in Cali and let them know how badly they blew it.
