Hi! I have a Triumph Thunderbird 900 2000 mod. So without further notice I suddenly started to get a "harder" sound. These engines have this well-known "whining/whistle", but now I think it's a kind of "thud-sound" I'm hearing through the whistling, or not thud-sound either, more a "harder" sound from the motor. This happened while idling also suddenly became higher. Must fix up the carburetors but wait for parts. But can I be in my head? Or is this signs of something wrong? Maybe I haven't noticed it before?
If you got no idiot lights, loss in power or compression, or real knocking, you are probably ok. These motors are naturally loud, many descriptions have been posted here to describe the sound.
Maybe the "thuddy" sound always has been there... I just tested it, really put a load on it in acceleration etc, and the bike runs like a charm all the way as before, just what I now start to think is me just noticed the "normal" sound from this motor. ??��???

Look for something loose. If it's something heavy, like a "thud" it could be something like a mounting bolt. If it's less "solid" it could be a heat shield or something smaller (like the horn...)
