Engine Resonance

[Mike_Honcho]

I have an 05 FZ6 and I don't know if it only happens on that year or on all FZ6's but between 5200 and 6200 rpm's there is a heavy buzz of assumed engine resonance under the seat presumably from the exhaust. I was wondering if this happened to anyone else or if anyone had found a solution to this problem.

All I have done in the past to avoid this buzz or rattling is ride at low rpm's but I feel I haven't been taking advantage of the power and full performance abilities of the bike up to this point.

Any suggestions?

I don't see this as an issue, - more like the nature of the beast.
Mine (an FZ6SA 06) does this too, - however i tend to enjoy it, not avoid it. It just tells me that the Bike's alive

I have heard, it is common for inline four engines to have a buzzy/vibration
zone. I had another Yamaha 600 and it's buzzy zone was 4000-4500.
The FZ6 is just further up the rpm zone. I just drive above or below that
rpm to avoid it.
Chicks dig it. Just kidding.
