Im JohnMoore from Italy but I live and work in Belgium, where in 2017 i got me the gsxs1000z.

106 Horsepower from factory limited ECU. top speed 240kph. but i think its just limiting rpm in 6thgear because at 7k rpm it wants to pull my arms off my body.

After two years i started lurking here and found out about the TPS fix, and these few days after receiving the infamous kawasaki part I finally got it setup correctly which definitely Improved the throttle.

I was goin to sell the bike this summer because to be sincere the bike was hard to control and I had a few scares while on full lean cornering.

I will track it this summer in Zolder, Spa Francorchamps and a few laps around the Nordschleife in August to really see if she's a keeper.

Only mods are short brake lever and tail tidy. next one is something called throttle tamer... im just starting the research on this so if someone has a good option that doesnt cost too much im listening.

thanks to all

Looks great! I have a throttle tamer on my 2018 1000z. Honestly, I did regret buying this bike a little because of the crazy power which made city/slow speed riding really uncomfortable. You have to be so gentle with the throttle when going through a turn if you don't want it to buck like a bronco that it made riding more of a chore than enjoyable. But after installing the throttle tamer, it made me change my mind. The power is still there if I want it, but the initial throttle pull is slower and more gradual making the bike more controllable. Some people have said the overall throttle turn from closed to wide open is a little more than stock but it feels the same and looks the same to me using the eyeball test (around 1/3 turn). Highly recommended and I don't know why they don't come with one stock since it's just a different cam design. I heard the 2020 Katana, which seems heavily based on the GSXS1000 but with different bodywork, is supposed to include a redesigned throttle tube cam though.

Hey john.moore.1.6td, Welcome to the GSX-S1000 forum! Nice to see your bike and hear the mods you've done and what you are considering next. You are considering a "throttle tamer" as your next modification, so I'm guessing your fueling is still a bit too 'abrupt' for your tastes. The throttle tamer will help. Before you buy it, ensure you've already tried to take all the slack out of your throttle cables except for 1mm to 2mm and try that. Sometimes there is just too much slop in the bike's throttle cables as it comes off the showroom floor. I'm guessing you already did this since you have done the TPS fix, too, but had to mention it. Throttle tamer is good but...

...getting your ECU flashed to make it fuel right would be even better. I don't know who in the Belgium area is any good, so hopefully some others will chime in.


As for the bike not being too confident inspiring at full lean, a lot of that comes down to two things:
1) The stock D204 Dunlop tires are really not that great. Not much grip and not confident inspiring. Replacing them with some Michelin Pilot Road 5s or Pirelli Diablo Rosso Corsa tires will make a tremendous difference. When buying new tires, get a 190/55-ZR17 tire for the back (not the 50 profile tire the bike came with.) If you still have a lot of life left in those D204s, start running 36psi in the rear and 32psi up front. That will get more heat into the tires and make them a bit more supple, which can help until you replace them.

2) Replace the rear shock. Just about ANYTHING else will be a huge improvement. The factory shock is over-sprung and has too much high speed compression dampening, making the ride harsh and out of synch with what the front end is doing.


Hopefully you can get the bike to the point you love it and just want to ride all the time.

Welcome John! I think frog is right about the stock tires and rear shock. I've got Mich R5s and they are a lot better than stock. I just recently upgraded my shock and it made a big difference too.
I lucked out and got one with no throttle issues, and I'm really enjoying it.
I hope you can get yours sorted out.

Im a pretty cheap dude. I guess I could try the 55 tall rear tire but a new rear shock seems expensive for now.
Im VERY sure the instability in corners came from throttle jerkiness. happened at full lean while tryin to hold steady throttle but instead of being steady its like i suddenly closed the throttle fully and too much engine braking went in sliding the rear tire and pushing my body forward.
During the whole corner I probably turn the throttle 1-2 degrees.
I remember with my 1989 zx10 streetfighter was really easy to modulate acceleration in the same corners and that bike was 250kg I think

my body weight is 62kg and I do understand the good argument for a better rear shock.

Throttle Tamer my friend that's what I did and it helped a bunch. I also had an 89 ZX10 that was a great piece of Machinery back in the day.

Throttle tamer is the only modification I've done to my bike, other than installing a 190/55 rear tire and filling the handlebar with BBs and installing heavier bar end weights to reduce felt vibration. Fueling has always been perfect, no throttle snatch, but the factory throttle was just too sensitive - fine throttle control was difficult to the point of making every ride a lot of work. Eliminating all of the throttle cable slack did help but I still needed to reduce the throttle sensitivity at light throttle, so I installed the throttle tamer. Mechanically, the throttle tamer only makes about a 20% difference in rate of cable pull, but man, what a difference that 20% makes in drive-ability. It completely changed the character of the bike, around town and on the highway. Every time I ride now I thank myself for installing that throttle tamer. I love this bike more every time I ride - I truly plan on keeping this bike for many years!

Dealer where i bought the bike asks 500euro to De-restrics the bike. but I doubt they will adjust the AFRs like a good flash tuner (I read Dano does it right) so Im definitely goin with the G2 tamer for this summer 2019.

btw anywhere in Europe that flashes stock ecu?

I did that with the power commander I thank myself every time I ride the bike

From everything you've said, and based on the real world experience from others, this seems like the perfect 'fix' for your bike. If you remember, pop back here and let us know how it works out for you once you get it installed and get a chance to ride the bike a bit.

UPDATE on throttle Tamer by G2:

After a month waiting on Belgian customs I received the throttle tube and The install process was pretty easy.

Results on the firs few commuting trips are promising I can now keep constant speed much easier and the first moments of engine acceleration are less abrupt. Feels much more like my old carburated bikes in throttle response.

Now my perfectionist side still says there is improvement to be made...

But now its really rideable. I have much more confidence when leaning hard and keeping constant speed in the turns.

Powering out of turns is also much more fun and the bike doesnt try to catapult me off the seat if i try to make small throttle corrections.

This is how the bike should have come out of factory in my opinion.

Yes there are tons of improvements but you whent in the wrong direction! I’m glad you fixed your throttle issue I hated mine as well I ended up getting a PCV

But the improvements are to be had in the ECU flash, and it will also solve your fuel cut issue what causes your snatchy throttle it’ll be a whole new bike, even smoother and much more power all round, your bike will run how it was ment to run

I finally went to my first trackday in Zolder in the beginners group with my 100HP gsxs THOUSAND. And the unrestricted 750s were pulling away from me on the straights Oh So Sad!!!! I did have massive amount of fun. I can now confirm this Bikes rear suspensions are not that good... my chinese short brake levers are going in the trash and the stock dunlops didnt seem that bad at all.

I am looking to upgrade tires and brake pads this summer... any suggestion are much appreciated.

and yes this restricted ecu is laughable I know... But a re-flash is for the winter pause.
