Gp shift problem, 01 zx6r

[Lazerus]

Okey, want to try the gp shift pattern on my 2001 zx6r. I have vortex rearsets which will allow me to switch up the shift knuckle's orientation on the shaft... BUT the front sprocket cover prevents me from being able to fully slide the knuckle back on when it is reversed.

The goober solution would be to hack apart the sprocket cover (or remove it) to make room for the reversed knuckle to seat fully, but I dont much like goober solutions. The knuckle has an offset bent into it, making the end of the knuckle that attaches to the shifter rod sit further away from the frame than the end of the knuckle that sleeves over the shift shaft. Is there someone who makes a knuckle with a bigger offset so that I can clear the sprocket cover? Anyone found an aftermarket solution?

I have searched barf and google for the last two hours, and pretty much come up with nothing but the "gp vs standard shift" debate, so any product knowledge would be a HUGE HELP.

most racers just remove the sprocket cover. however make sure to keep the chain guard/runner thats often mounted under the sprocket cover.

Any suggestions on what to do with my speedo sensor that clings to that cover?

 

[elskipador]

unplug it and leave it @ home. or take the cover to a machine shop and have them expertly cut the cover so that the knuckle won't hit it.

GP Shift Is not easy to get used too I have it on my 06 CBR600RR with the same vortex rearsets. You constantly have to get used to down shifting instead of upshifting etc. when it comes down to you getting used to it, I believe that you will find the shifting to be smoother and much better!!! but i'm definitely with elskipador on this. do what is most comfortable for you. You can even try just cutting enough off of the sprocket cover to make it work for you that way your sprocket isnt fully exposed or take your knuckle to a machine shop and see if they can cut it and weld it so it is more offset. But definitely only use the most logical/and price effective way to you.

I just cut a small portion off the bottom of the cover and it looks just fine.

Thanks for the help guys

I sacked up and hacked it to pieces myself.
Tools used:

8mm socket
10mm box wrench
Cordless 18v drill
Tapered bit
Sawsall
Polishing wheel

Strangely enough, the polishing wheel screwed up the finished look more than it helped. A steadier, more patient hand could have done a cleaner job, but I am a jittery impatient bastard! The wheel skipped off target repeatedly and left some nice scars on the cover. I tried to cover them with brown magic market I took off more material than necessary, but wanted to make sure that there was plenty of room as an insurance policy. Also, opted to keep some form of cover as a last line of defense for my waterpump should my chain break while riding. I used a marker to draw a center line across the shaft so that I could turn the knuckle exactly 180 degrees from where it started to try and keep the same leverage/ stroke as before.

First pic is before, second is after.

^^^^same here.....I had one oh shit moment coming down the hill towards turn 10 and oh shit Second gear instead of 4th whoops. But after the rear locked up I had the clutch pulled in before I got into any serious trouble. But all in all a good brown flag moment to say the least.

I think its time for a GP thread

Looks good man. even if there are a few oops spots. make sure you use locktite on all the screws(liberally). enjoy the shifting experience. I love my GP shift and it took me 10 minutes to learn it too but there were a few oh shit moments as well.
