Just jokes mate, hence the smiley face.
Geez, only thought you could get larger cams, not smaller. Nice one. Who's going to take the grenade and try one!? They're not cheap though.....
You may want to try a "G2" throttle tamer. They have different versions for quicker turning , slowing turning and adjustable turning for how fast the throttle opens. Some of the guys on the FJR forum likes them. I did put one on a customers kawasaki 1400 Concours. It seemed well made and installed pretty easy. I just checked and the FZ6 is listed...
Also, the tighter you can keep your throttle cables (without BINDING) it seemed not as jerky. I try to keep mine at taught as possible...

I agree with keeping the cables tight. But I read in a Sport Rider article recently about taking corners better. It may sound crazy but it works because I've been doing it works well on the street, waiting to try it at the track.
When you start braking and prepare for the corner usually you left off the throttle down shift etc. blip the throttle etc. All while doing that the chain receives tension and then slack because of the throttle. The article said to use the throttle to slow you down by keeping it opened. I read further and it said just crack the throttle enough to take the slack out of the chain and as go through the apex and nail the gas it helps take out some the jerk we feel and the suspension has settled and sort of preloaded and prepared for WOT.
I been doing that for a couple of weeks now and what a difference it has made on my cornering.

Yamaha Motorcycle Products and Throttle Tubes by G2 Ergonomics
I did think of different throttle tubes and even different throttle cams ....but that doesn't fix the lean condition that makes the bike jerky. I read today on Ivan web site that Yamahas fuel injection system SHUTS OFF THE INJECTORS when deccellerating below 45 mph...making the 0n/off throttle response a nightmare. He doesn't have fixes for the FZ6 either....just the FZ1.
Per my 2004 FJR Yamaha shop manual, yes, the injectors shut down. Not at a certain speed but from signals from the TPS. Should the TPS sense, the throttle closed /closing, (engine braking) "the ECU executes a deceleration fuel cut off". This is done for fuel economy. Charts are posted for injection rates at warm up, hot, de-cel, etc.
I suspect the FZ6 is the same but the speed has nothing to do with it, throttle position (thru the TPS)/engine RPM's do. With the stock ECU, I would think smoother on the throttle, (not turning it off fully) when cornering would help keep the ECU from going into the fuel economy mode...
Can this be adjusted thru a power commander or such? Or does the ECU over ride that on de-cel?
The on-line FZ6 manual doesn't address this.
Yamaha headquarters had the dealership set the TPS a little higher than the specified range, which richens up the mixture (how much I don't know).
This of course is telling the computer to add more fuel as the computer thinks there's more throttle opening than it actually is. So depending on how hard your engine braking/throttle partially on, perhaps adjusting the TPS to a slightly higher # than specified may help.
