I NEVER use my rear brake unless I'm under 20mph , so I have NO Idea what all the fuss is about, has anyone heard of down shifting ::) 
THAT is why we have a slipper clutch ... for DOWN shifting  .

Not trying to get into the "I do/don't use brakes" argument....just trying to followup with others to see if they did the "fix" that Randy came up with......and by the way,  our linked brakes are a problem.  I downshift, use front or back or both depending on road conditions, speed etc.....if you don't use your rear brake,  just disconnect it then (insert sarcasm and smile)????  See how this gets stupid fast.  So, no offense meant,  just trying to stay on topic....thanks everyone.

Me neither.  The linking can be increased or decreased (high and low mode) which is even remembered across battery pulls, and deactivates automatically at low speed.  But some people want complete control over the breaking, which the linking removes.  You supposedly can still trail brake effectively with them linked (especially on "low").  Yet I agree with them that it is annoying Kawasaki didn't have an "off" option instead of just "high" and "low" linking... it is a bit baffling.

I'm actually thoroughly surprised no one has seen/ posted this video on how the linked brake system works...

https://www.youtube.com/watch?v=nRqSTkwQRMM

That said, it's SUPID that Kawi thinks we need a computer system to determine proper braking ratio for us... It's not like we have front and rear drum brakes anymore... What if I want more rear brake to steer the bike into a corner, but still want to drag the front slightly?  even after almost 12k miles on this bike, I still go back to what I'm used to of not having a linked system, and getting surprised when I touch the rear brake.  And I downshift like a mofo when slowing down grabbing a handful of front and rear.

I would like to keep the ABS, as it's a huge safety thing on the street, but lose the links!

I don't necessarily think they they need to lose the linking option as much as they need to just offer an "off" option.  The sad part is that it is simply a software option that would cost essentially zero to add.  In fact, they could probably offer a reprogram retrofit.

Lol, thats what I meant.  The ability to shut it off.  I know it has its purposes for some peoples style of riding, but not for me. 



Here's another cool link I just came across.  Haven't fully looked through it but it looks pretty informative.

EDIT:  It almost looks like if we can disable the pumps, we can alleviate the issue...

Slick video. Makes it seem like we all need it to be able to ride. Problem is it is so abrupt and unpredictable in the application, that bothers me. Both my Gold Wing and FJR1300 were nearly seamless in the linkage.

  I am amazed no one else has chimed in on trying this.....so much original feedback.  Not that I don't believe Randy, I would just
like to hear from others reporting positive results.  Where are you folks????????

Drinking actually lowers my BP...which I'm doing now.

It's kindof like the throttle.  You open it JUST A LITTLE BIT and it hesitates, then says "OH S#!T I'M A MOTORCYCLE!  I'M SUPPOSED TO ACCELERATE WHEN THE THROTTLE IS TWISTED!" and tries to make up for lost time by applying all of that skipped power, all at once...

I guess your right, I went for a bike ride ... had a glass of red wine ... checked my BP
111/76 heart beat 69 ? I need to drink more... I guess :o

Hi

Great thread, I was guided here from the UK 1400GTR site, copy/paste of my post below, thing to remember here is mine is a trike: -


Having done nothing to the trike since last winter, apart from lots of riding, I have a growing urge to pull something apart soon .....

Issues: -
The traction control is a pain, it flashes up far to often when setting off in anything other than a straight line, this is because the ABS sensor is on one back wheel, and in a turn its either going a bit faster or slower than the front wheel, so the system decides to get involved, I don't need it, I have 2 large drive wheels providing loads of traction.

The ABS on the front wheel is great, but the ABS on the back is a pain, again because only one wheel is being sensed. This nearly caught me out last week pulling into a parking space, because I was turning right the right wheel was turning slower than the front so the system reduced the effort to the back wheels to nothing, causing me to have to quickly grab the front brake.

The linked brakes are a pain, despite my previous modifications to the back brakes I am still not 100% happy with them.
 
Solutions: -
Make a new sensor ring for the ABS and mount it on the front of the differential, this way it will average out both back wheels. Will need to do a load of maths to work out how many slots to cut in the disk, allowing for the size of the back wheels and the differential ratio.

Remove the ABS from the back brakes - make up a new pipe linking the master cylinder directly to the back brakes, but what do I do with the ABS pump?
I assume front and rear circuits are isolated from each other in the pump, so I can leave the front as it is, but what do I do with the original rear feed and output, blank them both off, link together ?

Your thoughts please

Richard

Yes you can, but should I put them here, don't want to hijack the thread?
Here's one anyway, Trike, Mrs and the dog.
