After some research and speaking to a few people i find out that some have gearbox issues.
As my bikes under warrenty ive been trying to get it booked in to get it sorted but ive been fobbed off for a bit with various excuses like try adjusting the angle of the gear change clamp that attatches to the gearchange shaft spline and try changing the oil etc etc..
So finally get it booked in and kawasaki refused to do it under warrenty as my bike is too modified.
Ive been arguing the toss with various people but kawasaki uk will not fund it nor will they even offer a reduced rate for parts as apparently the gen4 doesnt have any issues with the gearbox as it comes from the factory!!.
I find this very frustrating as mss and other kawasaki dealers and people i know all say that some gen4s have issues due to them not having good tollerences from the factory and they ideally need new components and reshimming to stop this occouring. If i want this done it can be done at a cost. After a good discount its still 900 pounds to do.
Im very angry with kawasaki as i feel i am being lied to and they know full well there are issues with the gearboxs.
Mine has recently had a quickshifter fitted that didnt help my case but my problem was there way before that so people need to be aware that if you have even the slightest issue that you need to act fast.
The bike must be completely standard. Anything relating it to track usage they will void it.
This is totally unfair as these are sports bikes supposedly designed for performance riding.
Very dissapointed with kawasaki uk.
I had my first false neutral on my GEN4 the first day I rode it with less than 1 mile on it. That was before I ever did a single mod and before I put it on the track. I ended up with such a problem I bought another GEN4 transmission off of Ebay from a wrecked bike. I had similar problems with that transmission. I have just come to the conclusion that the stock transmission in the GEN4 is a piece of crap. But since Kawi never admitted any problem and have never issued a recall or TSB I wouldn't expect them to pay for anything. I have a box full of gears and forks I've replaced. I have never had a single problem on either of my ZX6Rs and have never had a problem with my GEN5 gearbox.

Does a Gen 5 gearbox fit a Gen 4?

Ha. I asked that same question in another thread on here. :) I don't know the answer to the question but for me a gen4 bike with a gen5 transmission, an exhaust and flash, steel braided brake lines and good pads would be the perfect bike.

No issues on my gen 4 tranny. Had 5000km of track time on it and 2000km of street riding. I hit a couple false neutrals but that was due to the shifter being too low.

Do you mind me asking what QS you run? Although I do feel much of the blame falls on my transmission I do believe those problems are magnified by my QS. I have run the same QS on my zx6rs for years and have never had a single problem with them. I suppose another possibility is that not all of the transmissions were bad leaving the factory. It sounds like you got a good one.

I used a DJ sensor and the kit ecu. I didn't change the times much from the base map if at all.

I run cordona shifter with the maximum 80ms cut but the bike doesnt always engage within that 80ms so i just flick the throttle a bit and it works.
Mss reccommend translogic shifter as its a learning shifter and the cut times can be different for different revs and each gear has its own setting. It was next on my to buy list.

Lesson learned, if you want the manufacturer to warranty something, make sure they don't have proof of you modifying it beyond their specs.

FWIW I have a Gen 4 with a quickshifter and haven't had any issues. If I do, the Gen 4 has a cassette transmission and is easy to remove.
The bike had no shifter when i bought it.
I fitted it at 3500 miles to see if it would help it engage but it only helps in some gears.
Ive heard its easy to remove the box but there is the problem of the cost of the parts.
To replace 3 forks and 3 gears in mine it was 900 pounds.
Then mss said they could set it up correctly with shims so it changes good and this doesnt reoccour.
My point is if it needs shimming and setting up correctly then it obviously wasnt setup right when it left the factory.
Just recplacing the components means it would probably reoccour within a few miles.
Hence why i was pestering for warrenty but they just wont have it

The problem with the transmission is a really poor finish in general on some of them the faces on the dog's are so rough it prevents a smooth engagement so ultimately a missed gear occurs, the remedy is to get the dogs machined flat polished & back cut you will never miss a gear a again. Shimming does not really cure the problem as there is nothing wrong with the spacing just really shitty quality.

Ive heard of poor finished parts but mss shim these boxs all of the time. Its a very common thing and they have done loads of them.
Im thinking of whipping the box out and polishing and machining everything up spot on. But i would still need new forks and possibly a new gear to make it all mint again.
I really would like a online guide on how to do it though
