5th Gear False Neutral
« on: July 25, 2017, 08:13:10 PM »
Folks I'm getting a bit concerned, occasionally when going into either 4th/5th during a clutchless upshift the bike will either jump out of gear or go straight to a false neutral.  Am i the only one with this issue?
Im not one for banging it into gear either, I'm quite gentle with my gearbox

Take it in to get checked asap under warranty - mine had those symptoms to start with and turned into a costly exercise in replacing gear cogs, selectors and the gear drum. Unfortunately mine was out of warranty when it happened. Seems it was a defective gear drum caused the jumping out of gear and damaged the rest of the parts under load... :003:

Oh no, I've had this happen a few times now but only noticed it since fitting a quickshifter. For me it only happens when changing into 4th (quickly as well).

Is it an expensive repair to change drum? What we looking at?

Drum plus labour would have been around £600 but there were other parts damaged as a result, selectors, gear cogs etc.... cost me £1100. Apparently early zeds had an issue with the drums which Kawasaki will not admit officially.

If you've only noticed it drive Quickshifter fitted though take it to Dynojet centre to make sure the kill times are all ok.

I must admit I'm 'maxing' out the kill times and need to tone it down a bit. Still experimenting  :009:

Will increase killtime by 10ms between 7-11k band.

It's so s m o o t h at the redline!

Knowing how zed boxes are prone to 4th gear selection problems I would treat it more delicately. change slower and easier, ditch the quickshifter and use the clutch.....  :002:

If you have a bad one, you have a bad one. A QS will make the problem worse if it is already there  :003:
But QS's don't cause this with the boxes. Kawasaki do  :192:

Maybe but I'll ride mine old school and not take the risk...;)

I had the same problem with mine mainly 4th to 5th and mentioned it to my local mechanic and he asked if the lever was too high and I wasn't pushing up enough.  Funnily enough I've been more conscious of my gear changes and the false neutrals have massively reduced.  That would suggest it was user error but doesn't really explain why i it was mostly 4th to 5th?
