Looks like he hacked the shifter in half and mounted the rod piece on it?  Not sure.  When I get mine in I'll be able to see what it looks like better :icon_razz:

I bet he has done exactly as you said!

I bought a wrecked gs shift pedal (as shown in the photo I posted),

The thing is:

Where to cut it!
and how the attachment can be made. ( the rear brake I am realizing that can be trick also)

I will start the fitting this weekend probably. I can make some videos and post here... however my English is like .... sh!t  :cry:

I already will inform you all NOW.. aiming not accept complains latter...  :icon_razz: :flipoff:

Just kidding!


See you , guys!

Yup, as CBR said I pretty much hacked it apart and mounted the shift rod to it.  Sorry, stuck at work and likely won't be able to post a photo for a while.

Nothing rocket science to it.  I cut the stock shift lever about 2.5cm below the splined center.  Then drill a hole through the bottom end, to bolt that shift rod to it.  If you want to get fancy you can make that hole threaded, but in any case I would put a lock nut on the other side for security.

applause!

Tks!

If I you allow me to ask you one more question....(sorry if I am being too inconvenient)

About the brake pedal: Have you install the spring on it? The light switch of the rear brake it is functional on your bike?

In my mind, I am quite inclined to quit the brake light be functional on the pedal.... mainly thinking that no serious braking can be done with the rear wheel ( i Barely use rear brakes...) but if it is not a huge trouble I would be glad to let it functional...

tips and/or photos would be super.


tks

Hey happy to help a fellow GS-er!

No, I never wired my rear brakes for lights.  I try to always brake with front and back, so hopefully that light will always be working.  Though I think I'd prefer drivers to keep an eye on my bike in general, and not just my lights.

I actually ended up putting two springs on the brake pedal return, to make sure it always springs back to neutral so that the brakes don't drag.

Post some pics of what you've been up to!

Just wire it in so it's functional. It's two wires right? No biggie and better that way. My .02, humble .02

Good point...  the guy who helped build my bike hacked off all the original pedals and linkages, so not sure what the stock rear brake switch looked like.  If it were still around, I'd try to hook it up.

The CBR rearset is bare bones with no brake light attachment.

I know there's something like a banjo bolt sensor I can add, but I've never gotten around to it.

I ended drilling one more hole.. closest to the axis..I am using this one! Update: I am now trying the other mainly because the shifting was abit hard... I will keep you informed, besides that... so far so good!

Today I intend to test the bike for a few hours..

Nice video Kito!  Good choice of music too  :cool:

Looks like you've got a great workshop to tinker.  Where are you located?

Have you had a chance to take the bike out for a test ride?  On your brake level, I'd keep a close eye on that rubber band replacing the return spring.  Rubber is likely to crack and corrode, especially if close to the heat of the exhaust.

Cheers Endo!

Thanks for your compliments! I really appreciate that!

The music was free to used in my video editor... Filmora.

I am located in São Paulo , Brazil ... one of the reasons that  I like to maintain my bike in the low profile (aesthetically).... 
for instance, the tank is from a wrecked bike...
There is a huge market for parts from used (stolen) bikes.. :2guns:
The second reason is that when I go for A real ride... I go "prepared" to fall. :cookoo:... so there is no point for a fancy shiny bik for myself. .. And now I am preparing my bike for track days also).

Instead, I decided to invest in a workshop... I cannot say that I am not equipped reasonably ... It is nice to have things on hand.

BUT FOR THOSE INTERESTED IN INSTALL THE REARSET KIT.... ITS IS NOT NECESSARY ALL OF THAT! I hope to people noticed that.. A saw,, a power drill, 10mm drill and an M6 tap kit.. will do.
so..

Today I rode it for about 1,5 hours today.... The beginning was harsh... down shifting to first gear it isn't a beautiful scene.. LOL >:(
Moreover ... when you accidentally downshift... usually you were going in high revs intending upshift.

The muscle memory is unforgiven... the reverse shifting when done without previous thinking is, as expected, unpredictable.

But at the end, things got smoother... but I expect at least a full week to my brain adjust.

About the rubber.. yes I will keep an eye on it! But if it breaks on a ride.. for what I tested, I do not expect a problem.. at least something to be very concerned about it.

MAybe I will look for a better quality rubber...  well... things in that bike are always under test and under supervision...

In a few weeks, I can make a review of how things are going with this project.

PS My wife loved your bike.. she could not believe that we are riding the same model... LOL...   :confused:

GP shifting is a learning experience.  :laugh: It is great for catching the next gear when exiting left-handed corners.

Kito, why reverse shifting?  I got this kit to eliminate the reverse shifting.  :dunno_black: 
It's early and my brain isn't braining, so forgive me if you already explained all that,....

Hey CBR, how is it going?

Before I start to write.. I googled some pages to search a good content to you have a look.

However, I took one phrase that is the core of your question:

why reverse shifting?

"The biggest benefit to a reverse shift pattern on the track is that upshifts are easier to make while you're still hung off the bike exiting a corner. This applies to both left- and right-hand corners, though for different reasons."

The MAIN intention is not to get your foot caught in the asphalt while upshifting in a left-handed turn exit!
But there are others pros and cons.. check the links if you can!

Obviously, I am light years from a GP class rider, however, I like to have fun in:

  • inspired ridings
  • try something new
  • ,and tweaking my bike!


Cheers!

Ah, ok.  I did reverse shifting on mine because I couldn't get the shifter rod set up correctly to shift in regular style.  When I saw Endo's set up, thanks to you, I realized I could set mine up to 'not' have reverse shifting.
I realize now that you 'want' reverse shifting.  10-4  :thumb:

Yes I Do!  :woohoo:

At first I was "copying" the Endo installation... And Yes... the regular shifting is much more complex to
set ( in this kind of kit) because of the interference between components... t

Thank god that for reverse style was a lot easier.

Yesterday I ordered a Folding foot rest.. I am a bit concern that when I go down... The footrest will break but  before that it can bend the part of the frame where the set is screwed.

OK,

Let give you some thoughts about gp shifting style after about 3 months of testing.

First of all to get used to the reverse is not a walk in the park

I have some theories why... but I do not think that is the place to debate it

The first week is a hell.... after stretching the revs..9K.... aiming to upshift... you end downshifting.... ugly thing to see!

the errors decrease exponentially... in this way ..
in the first week... you got like 15% of erros... the second  7.5%, the other...  3.75%....

as you can see .. difiicult to get at 0%!

Pros:
Really easy to upshift in left or right handed turns!
No one will steal your bike.. lol
no friend will take a ride
Is kind of cool

Cons:
When in down shifting in a hurry.. you need first to get your foot under the lever.
You will suffer to ride in someone else's bike.
The Pros doesn't add that much to average rider performance


the project is working as it should.. a thread lock glue is desirable

Cheers

I have GP shift on my bike, and it did take some getting used to. I also have a 2017 DR-Z 400 that i ride on the road and that has stock a stock shifter. It's just a matter of thinking about what gearing each bike has. Once you get your head around it you will be fine.
I do agree about revving the bike out to 9,000 RPM and then changing down. It's a real PIA but you learn quickly not to do that.
No matter what i do to it, it's still a GS
It's not how fast your bike is, it's how long you are prepared to hold the throttle on.
