The bike apparently has an outstanding TPS recall on it so the local dealership have ordered a new part and i'll be taking it in for a replacement shortly. filter this eve and spark plugs at the weekend.

So, an update on this.

Out for a ride yesterday and after covering about 80 miles the engine started to cut out. Only when at idle though. I've taken a recording of the noise experienced as described in OP as wheras before it only happened at speed, this time it was happening whilst stationary.

When I (finally!) got home i thought i'd check the air box due to the weird suction noise as suggested above; the air filter was a state so have ordered a new one and I checked the spark plugs (well, i check #1, access bit of an issue with the others). It was black so it looks like the engine is running rich at the moment.

Got new spark plugs so I'm going to try the radiator in change I've seen on here and once the filter turns up, will change that. Hopefully that sorts the problem. So far as I know the engine is standard so no reason to suspect anything else. Unless there's a problem with the FI. Have contacted Yamaha to check for the TPS recall issue as well. Pending a reply from them having provided VIN and Reg.

If not will post the recording of the engine noise and hopefully some kind soul can provide insight

Hi all,

I have recently purchased a 2004 FZ6 26k miles and although it's a fantastic bike have noticed a few things i'm hoping to get help with.

It's my first bike so don't have a baseline to compare it to beyond what i learned on (xj6) but the fuel economy seems shocking (~100/tank).
When warm, I've noticed a kind of wet warbling noise from the engine when engine braking, it's like a valve is open or something as the engine noise is a bit louder and clearer than normal. Then, when the throttle is re-engaged, it's like the window pops closed and there is actually a kind of sealing noise again like a window or valve has been sucked close (there's no sucking noise, almost like a pop like liquid has sealed the hole) and the engine sounds normal again.
