Snatchy Throttle Issue

[villa1963]

Having read a number of reviews before I bought my FZ6 S2 I was aware of the snatchy fuel injection problem.Up until yesterday I felt confident that with time and practice this could be overcome.However yesterday it damn near caused me to crash on a roundabout when I needed to power on in second to avoid a nutter in a BMW (arent they all?).In general I have largley managed to compensate with careful clutch/throttle control but its still there and a worry that taints an otherwise great ride.Has anyone else managed to find a technique to overcome this?

The only time I get a big bite from the throttle is when my chain is a bit loose, I over come it by very slighty pulling the clutch when bringing the throttle on. How loose is your chain?

Had big issues with a snatchy throttle till i got my exhaust de-baffled, for some reason, when the exhaust was allowed to breath about 40% better, the snatchiness dissapeared. Am guessing an aftermarket exhaust, and, or a power commander would also fix this problem.

i haven't really noticed the snatchy throttle syndrome yet (6000 miles so far this year) so i would assume that it would have shown itself, how new are you to riding? also the loose chain could be causing it as well,

throttle and clutch control is the real answer but if you're looking for mods you can...

change the final gearing and run a gear higher than you otherwise would

get a PCIII and tune (or so I've heard)

mod the amount of rotation required (increase) to put the throttle to the stop

buy a different bike

I had that same problem. At neutral throttle, like in a sweeper, I'd try to dial in little more throttle...and....wait...and...wait...nothing. So I'd grab a handful and then BANG! UGH....I've never had a bike that did that before. Over the past few weeks I've installed a PCIII and had it dyno tuned and a custom map created for it. 90% of the problem solved. The throttle is much more responsive to small inputs. It's isn't smoothbore carbs, but it is much better than stock. The extra torque and hp is nice too.

The tuner stated that is one of the issues with FI; and each brand and model of bike is different. Once he had it tuned he was very impressed with the throttle response and this is from a guy who has been doing this for 20 years.

I'm not sure if the addition of the O2 sensor in '07 has anything to do with this or not. When you are at 0% to 10% throttle position, and between 0 and 7000 rpms, the FI system is closed loop, meaning the computer governs what the FI does regardless of what is programmed into the PCIII; kinda sucks that it can't be tweaked.

I'd like to hear what owers of R6s, SV650s, and other small displacement FI equipped bikes what their subtle throttle response is like.

If you choose to go with a PCIII you are welcome to use the map I had made for my '07. I have an Akrapovic exhaust with the DB Killers out, but I have a feeling that regardless of aftermarket exhaust it will still work well, ie: better than stock setting.

Hope this helps.

I drive a manual cage, which, when engine braking, gives pretty much the same result: engine is loaded, need a little extra speed, press accelerator, nothing, press a little more, whoa! - this is the long way of saying that I'm used to needing to 'reset' the clutch when coming around corners in the cage, it wasn't much a stretch to apply the same technique to the FZ6. (slow down for corner, pull in clutch, lean in, throttle up, let clutch out slow)

Are we all talking about the same thing? I have it but mine is due to a way too strong throttle spring. The reviews were right about that in my opinion. Shouldn't be so hard to pull on the throttle. not a big deal but its there

It is a stiff throttle, isn't it! I get caught out by the delay between opening it and stuff happening, but the missus doesn't (on the same bike), but... she'd ridden one nearly every day for four years.

I think I'm experiencing the same thing as you. Often when coming out of a turn I'll roll on the throttle, only to have the bike initially jump. My chain has the right amount of slack stated in the manual. I'll look into the PCIII, though I'm not sure exactly what it does or what you guys are talking about by "maps".
