After putting 3,800 miles on Burgman it seems to be getting louder as if the intake and exhaust ports have gotten bigger :) . I thought it was all in my head but recently my dad and an older friend have both said theyve noticed it too and theyre both hard of hearing. I have done no mods to it yet and it doesnt seem to be getting any quicker or more powerful so Im wondering if anyone else has had to same phenomenon?

EKP, the valves get tighter as they wear in. If you haven't had them adjusted yet, its probably a good time to do it. Suggest you do it yourself to make sure its done right.

Ted, I had my vavles checked by an independent shop and valves were right in the middle of the specs at 4,050 miles. Found the noise coming from a disconnected vacuum hose from the airbox cover.
