How exactly does GP shifting ease the wear on the transmission, its just the linkage that gets swapped around the forks and everything still move in the same direction its just the linkage and rear set that are changed :O

I've done this on my 05 zzr 600. Mainly happened when I first rode I'd shift to second and hit the gas and it would pop into neutral (could feel the shifter move). Think it's from not fully being into second gear.

I use to thing the same because my 99 250 would have a "false neutral" but it took me actually getting in the engine to find the problem. I will be doing a rebuild within the next year or 2 on the 01 engine and I might do a write up on how to fix it.:O

From what I understand (Please correct me if i'm wrong) the second gear issue for this year is usually caused by missed shifts combined with the weak gearbox. With it converted to GP you shift harder, reducing the risk of missed shifts and saving the tranny. But this is just what i've gathered through trying to figure out how to fix the issue, so it could be wrong. :O

 

[jerryx2000]

@ZPVanT ist your problem solved since the repair? Any issues after that?

 

[Enrosabil]

ZPVanT sums this up quite well.
This is not a problem for this bike, this year or anything like that.
This is a problem with almost all sportbikes, the ones ridden in cities and the ones used by stunters or wannabe stunters mostly.
Loads of effect when shifting on high revs and people who cannot shift gives this problem.
It can also be a bent shaft in the gearbox, caused by the same thing.

Also, when not dialed in correctly, it is harder to shift "As usual" compared to GP shift as you call it, wich causes this to happen (shifter placed to high, not moving the shifter enough, letting up the clutch when second gear is almost in, and loads of throttle...)

The other good thing about GP shift is that it makes you able to shift to next gear in a bend without risking getting your foot stuck under the footpeg and broken in half.

^ sorry mate but that's simply not true. The 05/06 gearboxes are known to be weak, 2nd gear in particular. I've read way more threads about gearbox issues on this year than any other. I can see why gp shift might help preserve the gearbox like you said, but these boxes are more likely to fail than the others as far as I know. The 03/04 weren't great either and I've had mine replaced once, although I don't think my bike had an easy start in life....

And by chance I've just seen another thread on a nackered 05 gearbox on the homepage

The new models have a positive neutral finder so if you're shifting from 1st to 2nd half assed, you're going to end up in neutral. You'll also be surprised how many people say help I'm at a red light and I can't shift into 1st, I'm stuck in neutral....same ordeal....positive neutral finder...roll the bike forward or backwards just a little, and boom, it will shift into 1st.

Some say forks are worn, but if your forks are worn your dog teeth are worn. Just start looking for a used transmission including forks and drum on eBay or the forums. Try to find a local tech with a good reputation to do it on the side for you.

I replaced mine myself. $100 fix. You could also get fancy with it and send your gears out to get back cut.

all this chatter & still not answered :O
You have a problem with the dogs & petals for 2nd gear. The fix is to either have them re-cut or replace. If you think you can do it, it would be way cheaper to replace the bad gears because to have them re-cut, you have to send the whole transmission (2 shafts of gears) to a place to have them machined, n it ain't cheap :thumbdown:

Here's a link showing the tranny parts:
2005 Kawasaki NINJA ZX-6R (ZX636-C1) Transmission | Babbitts Kawasaki Parts House

It is most likely 13260B and/or 13260E which are the 2 gears that mesh for 2nd out. But you will need to remove the engine & remove the trans to eyeball the input gears as well.
The last couple trans I fixed was just much cheaper & much less time consuming to replace the gears :headbang:

You could try a GP shift swap, maybe it'll help but in the end you have a gearbox problem and that's only going to help you short term. Converting to a GP shift pattern is super easy. You can either buy a set of aftermarket rear sets that are designed to accommodate a reverse shift pattern, or you can add a few washers and fiddle around with your stock linkage and ta da - GP style shift. HOWEVER, if say, you're running up to red line in 2nd and you FORGET you have a GP style shift and from force of habit you accidentally shift up instead of down - ugly shit happens.

Sorry, missed it dude :O I thnk you posted while I was typing

I guess that was for me.
Would you explain why owners of 98-09 r1, 00-08/09something r6, 06-08 cbr600, early fireblade, vfr750, zx10-08, fz8-11 have the same problem? (This is just people I know...) You are saying that Honda, Yamaha and Kawasaki cannot make a functioning gearbox? Or could it be idiot owners? What gear is the easiest to miss? Would you say there is a connection between a gear that is easy to miss and the gear that usually gets the most pounding and tells you that your gearbox is shot?

Complaining about that gearbox for breaking is like complaining on a pencil since you couldn't use it as a hammer when building a house.

 

[Enrosabil]

Oh, and furthermore, it is ALWAYS second gear, does it really feel that strange to you, that a gearbox that probably have been quite abused for 8-9 years will break?

 

[d1andonlyant]

All I'm saying is when I see a thread on the homepage about gearbox troubles it's normally the 05/06, so unless that year attracts a certain type of rider for some reason, I'd say there's more to it. I can see why 2nd gear would be most likely to fail but I don't see why it happens on 05/06's more than any other year if the gearbox is just as strong? I didn't come up with this theory and I'm no mechanic, just a forum regular, but judging from the threads I've seen over the years I'd say the 05/06 gearbox is weaker than the others. I've got nothing to base that on other than what I've read online so if you have more hands on experience and are sure it's bollocks then good for you, I'm just going from what I've read over the years

Yup, known issue with the 05/06, particularly with a track or stunt bike.

I think it has to do with excess endplay in the tranny which can cause shift fork bending and excessive wear, damage to the grooves on the drum, subsequently inconsistent sloppy shifts, and eventually worn dogs.

The real kicker is that on this model the motor and tranny share a casing so to tear into it the motor needs to be dropped and casings split.
