off/on throttle snatchyness

[Pizz]

I've found the same issue, but only in first gear (and sometimes in second). Does this happen in all your gears? I smooth it out with a little clutch.

1st and 2nd is not a problem. neither is shifting. bike shifts as good as i can expect. is not a problem in 1st and 2nd because i am not riding too aggressive that slow and there is only so much traction and it would be a very tight relatively slow corner. i am only looking for improvement at aggressive higher speed where i need to be on/off/on throttle applications. it is especially apparent in unknown corners with crappy pavement, gravel, etc and i am going a little too fast and just need to close throttle and want to get back on without braking or a shift. i could take a little longer and slower to get back on the throttle but i like to not coast mid turn. i do not drag race the bike, am not looking for more and earlier lower mid range pull, or run open high speed straights without having to let off for potential hazards (well, maybe sometimes and the bike does this insanely good). again, it is all good on smooth, more civilized pace or familiar roads where i dont need to close and open throttle quickly. so....it seems it be the fuel injection shutting off fuel at 0 throttle and a tiny delay when opened. if it is fuel injector delay caused (like all fuel injection bikes) throttle application or use of a g2 throttle tamer is not going to help. neither is a tre. i was just hoping someone has a solution for this particular bike. there must be some fi tricks racers use or maybe it just does not matter as the tiny jump isnt going to put the bike in slide because it is just only at throttle tip and not enough torque to step the rear wheel out. i'll bump up the idle a tad and see if that makes a diff. again, this is serious nitpicking as bike only does this a tiny amount and it is about the only thing i think i can improve on as there doesnt seems to anything else. the direction with custom mapping sounds promising as like cars with more sophisticated systems to eliminate throttle tip in jumpiness. but has anyone achieved complete throttle tip smoothness with this bikes fi? or is it just not possible. anyone's input with more experience or technical awareness on this particular bike with this particular situation is most greatly appreciated!

Phil i know what you are talking about buddy, however i believe that is just nature of the beast.. these bikes are big CC's which means big compression and when you let off kinda like a race car you are going to get an immediate drag and then back on it is almost like it jerks you and it is hard to smooth out. when i first got my bike i thought maybe the brakes where sticking and let of the throttle a couple of times and big movement (appeared to be foward) what made me realize it is just the motor because when you pull the clutch in the drag goes away so it is just the drag of the motor...i have gotten a lot better (smoother) with easing on the throttle, however every now and then it feels like it wants to buck me off of it...... i love it it's like a brotha riding a bull lmao

I have a 1400 GTR. I also have the problem with occasional 'snatch'. I believe it is the FI causing it. It does cause anxious moments, because if it happens on a gravelly corner or wet white line ....well you know, and this is a big bike(handful) if it steps out, especially with my wife on the back. I have fitted the throttle tamer to mine which does allow the roll on to be smoother, which is great for touring/cruising around, but it is not a cure. The biggest help was to wind the throttle up to 1300 rpm. Doing this removed most of the hesitation before the snatch, maybe a little higher would be better, but I don't like engines that rev high at idle. I'm hoping for a fix when I get a Power commander, ie if it is capable of tuning it out.

OK, look, it's not his shifting technique, so quit bugging him about his crummy shifts. It also has nothing to do with the oil, the chain, the tires, or the phases of the moon. I contacted a regional factory rep who's a whiz with these things and here's the skinny: It's the mapping of the ignition from first through 5th. In its wisdon, and to keep the Feds from throwing a hissy fit, Mother Kaw, in order to keep the EPA police at bay, mapped the computer on the 14 (and the 10, and Suzuki did the same with their Haya) so that, on throttle roll off, the whole timing goes into major retard mode. This is the way that the factory keeps the bike clean on decel. The problem (as most of us have discovered), is that on throttle roll-ons, especially in the corners, the power comes on with a real bang.....scary, if you're trying to smoothly accelerate out of a sweeper, and find yourself in the opposite lane. Myself, I got tired of it, called to find out what it was, confirmed the diagnosis with my local tuner, and then went straight to the HealTech website, and plunked down the dough for the GiPro with the TRE. What this little circuit does, is to fool the computer into thinking that the bike is always in 6th gear (which does NOT have any timing retardation built in), and allows much smoother power delivery in all gears up to the top. It's about $170, takes approx an hour to install (due to some rerouting of wires), is reversable, and frankly was a Godsend for me and my riding style. It's one of the few mods that actually does what it's supposed to.....and the large gear display is pretty sick, as well. Highly recommended, 'cause it does the job.

yup, bike shifts pretty sweet! snicks off shifts nicely. so, looking for a solution, i took ALL the throttle slack out and then some and viola!, no more scaryness. well, just a tiny amount. i thought i took all the slack out before and didnt find it any better at all so i gave up on that idea and was thinking those who solved this this way just werent riding like i do. but needing a fix i thought i try it one more time and then give it a little extra tightness to make sure. thought i liked a little play but now i dont. even the dealer didnt suggest this and i had them re-adjust and they did so with play. i am now thinking kawi actually engineered it for zero slack. trial and error, i guess. i can still make it jerk but then i have to try to do so. time will tell if it's enough as i re-build my confidence in aggressive pace. if another $170 could make this bike any sweeter, i'm in. but i am not sure a tre will help me as i wasnt able to roll on and off throttle as smooth as i want in 6th over 200kmh or so. but that was before, a tight throttle really does help and for me, time will tell if it's enough. Thanks for all the input....ride on!

I had 1500 miles on my 14 and changed to Amsoil and you can feel the differance as soon as you ride it.....

hey phil thanks for the advi on the cable... i never thought about tightening mine, but it always have felt a lil play in it.... after reading your post. i messed with mine and took all the slack out, and it feels great. i rode this thing for 4500 miles just thinking it was like that, but on the 4501 mile i tightened it up and feels a lot better.

i currently have mine so that throttle doesnt snap back but very slowly goes back with the zero slack. probably not supposed to do this but i seem to have better control this way, doesnt seems to have as much FI delay and is more predictable. also more relaxing on right arm. hope it doesnt prematurely wear cables...
