Hello all. I bought my 07 C90T about a month ago with 12,780 miles. I have put about 3,000 miles on since. I changed the oil to 10-40 royal purple and changed the plugs to the hotter option as per the manuals suggestion because the plugs in there had white insulators. I don’t know if I’m just notcikg the noise now that I’ve had the bike, but my engine seems to be way too noisy. It has what I would describe as a distinct knock or clatter. Here is a link to a quick video I took tonight. It sounds like a clatter, and then theres a kind of ringing, like someone tapping a glass with a fork. PLEASE someone tell me this is normal, or if they have a similar sound.
