Quick shifter

[mike]

All I can say is that it is fun pulling out of a corner and running up through the gears with a strong, even if not pinned, throttle with the QS. Is it necessary? NO Is it fun? YES. True, there are some other things that I might rather have as part of the overall package but this is what was offered and I, for one, will be using it on occasion and grinning the whole time.

Very good point!  The answer is that it is a pointless sales gimmick.  It's a road bike!  You are almost never going to need a full throttle up-shift.  In any case, the time saved even on a track day compared with no clutch/dipping the throttle (that's how we raced for twenty years before they invented quickshifters) is insignificant.  There are an increasing number of gimmicks like this that sound impressive and are cheap to implement.  Multi-level ABS and traction control for example.  I prefer they spend the money on a proper fully adjustable rear shock.

I wouldn't consider multi-level abs and traction control as gimmicks.

abs on the GT is excessively intrusive and cannot be turned off. 

Both traction control settings are overly excessive. At least this can be turned off. 

I think a lot of people would welcome improvements on these systems.

I had my ECU reflashed and since then the quick shifter seems to work a bit more smoothly.  I used it repeatedly just to be sure it was not my imagination.  There was no provision in the reflash for the quick shifter.  I am guessing that maybe either the revised ignition timing or new fuel maps may have some positive effect???

I don't agree that it's a sales gimmick.  It's not there to save you time.  I drive a car with a DSG gearbox (Direkt-Schalt-Getriebe) and a racing car with Geartronics pneumatic operated paddle shift,  both of which allow similar open and/or full throttle clutchless up and down gear shifts in a few milliseconds.  One of the advantages is you keep both hands on the steering wheel.

I find that the quickshifter allows more control over the bike because you don't move your hands to upshift,  just your left foot a little.  If you're accelerating hard, maybe overtaking, crossing the central white line and catseyes maybe, whatever, you have less to do, have better contact with the bars and therefore more control.

I like the QS, wish it downshifted too sometimes, but actually when you are downshifting, your weight is more on the heel/palms of your hands anyway and your fingers are un-weighted and free to waggle the lever and twist the throttle, whereas while upshifting and accelerating, your fingers are busy stopping you falling off the back of the bike.  Of course we all hang on with our knees too!

I'm curious about your comment that the ABS is too intrusive.  To my mind if the system detects that you have wheels going at different speeds, whatever the % of slip they programme into the system, you have a front tyre that is slipping and therefore the % likelihood of your head hitting the tarmac is also increased.  I presume that Yamaha and whoever set up the system, build in a safety margin for their customer's benefit.

This paragraph from Wiki is interesting as it mentions the rear wheel lifting, which will activate the ABS and take away some front brake.  My dealer told me that somewhere in the maintenance menu is a log which will tell them if you have been cleaning your chain with the engine running.  They know this because the front wheel isn't moving.  And they can then tell you off!

"Basic principle

Wheel speed sensors mounted on front and rear wheel constantly measure the rotational speed of each wheel and deliver this information to an Electronic Control Unit (ECU). The ECU detects on the one hand if the deceleration of one wheel exceeds a fixed threshold and on the other hand whether the brake slip, calculated based on information of both wheels, rises above a certain percentage and enters an unstable zone. These are indicators for a high possibility of a locking wheel. To countermeasure these irregularities the ECU signals the hydraulic unit to hold or to release pressure. After signals show the return to the stable zone, pressure is increased again. Past models used a piston for the control of the fluid pressure. Most recent models regulate the pressure by rapidly opening and closing solenoid valves. While the basic principle and architecture has been carried over from passenger car ABS, typical motorcycle characteristics have to be considered during the development and application processes. One characteristic is the change of the dynamic wheel load during braking. Compared to cars, the wheel load changes are more drastic, which can lead to a wheel lift up and a fall over. This can be intensified by a soft suspension. Some systems are equipped with a rear wheel lift off mitigation functionality. When the indicators of a possible rear lift off are detected, the system releases brake pressure on the front wheel to counter this behavior.^[37] Another difference is that in case of the motorcycle the front wheel is much more important for stability than the rear wheel. If the front wheel locks up between 0.2-0.7s, it loses gyrostatic forces and the motorcycle starts to oscillate because the increased influence of side forces operating on the wheel contact line. The motorcycle becomes unstable and falls. "

 

So why do you find it too intrusive?  Are you generally late and hard on the brakes.  Are your tyres worn unevenly?  Is your road surface crap?  I can see that traction control needs to be adjustable to suit the rider, but not ABS.  Either the front is slipping or it's not, surely?

I like quick shift. Not a determining factor in buying a bike, but it is nice to have it. Auto blip is pretty gimmicky, if it had it I'd probably use it,  but it is still gimmicky. 

I own 4 bikes, the GT being the only one with ABS. Though, I've ridden older bikes with ABS and current ones with more refined systems.  

While the system on the GT is better than earlier iterations of 2 wheeled ABS, there are other bikes manufactured in the last 5 years that are miles ahead. 

When coming to a hard stop, it'll kick in well before it is necessary, increasing braking distance in an emergency stop. Probably, not by much, but I would like to be able to dial it down, or turn it off. 

On dirt roads, I feel a lack of control as a result of the fixed abs system, not being able to lock up the rear wheel is a hindrance on dirt. 

It isn't a huge gripe, but there are better systems.

I see.  I wonder if because the bike is designed to have a pillion and luggage, Yamaha set the parameters based on a potentially fully loaded bike, so when riding solo, the abs feels a little too cautious?  Presumably an army of Yammy test riders throw the bike down the worst bits of road in the worst circumstances until they don't fall off and then settle on %slip rate to cover themselves when their customers find themselves in not such bad circumstances.

Sorry this is getting a bit off topic.

When I drive a car on snow, the sensation created by abs of ploughing straight on is alarming when you know that a locked wheel is going to stop the car quicker.  Fine if you need to steer to miss the car or whatever to avoid hitting it, but annoying when you are braking in a straight line.

When I was about 12, (1970's) I went to a BMW promotional demonstration of their world-first new ABS equipped cars.  Hired Le Mans winner Derek Bell hit the brakes at 80mph on a wetted Goodwood track.  Unfortunately the spectatators thought they had told him to brake on this line and he'd be able to stop before hitting the cones, which would have been impressive.  But with the abs turned off, he skittled the cones and everyone there thought that these new fantastic stop-on-a-sixpence brakes were not much good.

Next run, with the abs on, he hit the brakes, last minute swerve and missed the cones, then eventually stopped a couple of car lengths further on than before.

So the demonstration didn't impress much because the expectation then (as now) is that ABS will save your bacon and magically stop the vehicle quicker than if you lock up the wheels.

The best bit though was when the customer rides were just over and my Dad blagged me a ride in the front passenger seat around the circuit with Derek in the black 528i, now with shagged tyres.

I had my T9 in for 600 mile service last week, dealer told me not to run engine in gear  when lubing chain or it will flash a fault on dash. I told him I already had and all good, wheels turning at different speeds. They didn't know, I told him.

I might try and change my habits tho.

Has anyone adjusted the gear lever position?

Is it possible to adjust since the GT comes with a quickshifter installed?

Has anyone done it yet?

Looking to adjust the gear shifter lever lower by a tad bit.

[Michiel900GT]

I use it almost only when entering the freeway. It is a great way to get to the 120km/h and be able to control the bike.

I almost never used it otherwise. But that might be because it tend to shift gears at ridiculous low rpm. Maybe I need to buy a different bike.

You guys get the Tracer 700 over there.  I've always thought that would make a really fun commuter type bike.

Easy peasy. I lowered mine down as soon as I got it home.

Yup. Just adjust the rod. I didn’t feel like trying to disconnect the wires so I could rotate “the rod” on the LH&RH threads so ended up pulling the shift lever and disconnecting the rod. 
 

Shift lever pivot needed greased anyways. ..

thanks guys!

Can someone confirm which gears the QS works on, I read 3-4-5-6.  I will 100% attest that mine works from 1-N-2, 2-3, 3-4, 4-5, BUT does not work on the 5th-6th shift.  IDK if it has to do with my 17-43 sprocket change.  I sure thought before the change it was QSing 5-6 also.  Almost positive....
