So, when the bike is idling, I can hear a buzzing / whirring sound when I put my ear up to the tank. It's audible from a distance too, but clearly coming from the tank when I put my ear up.

Is this just the fuel pump? Is this normal?

I can hear it the second I come to a stop while the bike is running.

Thanks! :)

Cooling fan?

When you hear the sound, get off the bike and listen near the tank on the right side of the bike. If it sounds like a ticking sound, it is the cam chain tensioner.

Unlikely to be the fuel pump. The fuel pump(as with most Yamaha sportbikes) kinda 'ticks'-unrelated to and a totally different sound than the dreaded CCT tick. It's possible it's just some of the unique noises this motor makes, magnified and resonating inside the tank itself.

It's definitely not the fan, as I know that sound quite well. :D

It's not the CCT, as I had the issue ages ago and have the Fizzer fix in place, as well as the revised tensioner.

This is audible if I put my ear on the gas tank.

It may be nothing.
