Title: Difficulty finding neutral
Post by: VladTepes on Monday, 14 January 2019, 10:32 AM
This morning at the lights...

1-2-1-2-1-2-1-N

Happened like this several times (but not every time).

Anyone got any ideas on what may be causing this?


It's a K7.

Not really Mike, but this could be part of the Tap in the arse you received  ;) ;)

I take it the oil has been changed on the regular intervals ?

haha I don;t think so.

Yep oil changes regular and it was serviced just before the MCR.

Clutch not disengaging completely?   Ya haven't got shorty levers on have ya?  Been adjusting the position by chance? 

This'll be a good one to diagnose & fix . . .

Could be worth checking a few things
- is the clutch pushrod sticking?  You may have a build up,of muck and goo from where you've oiled your chain that has built up over the months.
- when was the clutch fluid last changed? Fluid level? Fluid clean or black-ish?
- chain needs adjusting - could be a bit loose (or tight) - or chain may have a tight spot possibly

Different shoes / boots?

Shifting too fast to find neutral?

Oil cold (in Aussie??) n basket sticking? till it warms up

IMO, clutch not releasing fully mate. Just bleed it, see how you go, 14 is one of the best ive had for finding neutral.

As @gsxbarmy said check the clutch slave cylinder is ok as they get crudded up and can stick making the clutch operation not as smooth as it should be .
Good luck
:cheers:

Finding neutral is usually pretty easy. Make sure linkages are as they should be. I had to pinch my shift lever up. It had become a bit loose on the spline. Does seem a bit odd.

I know it sounds wrong but is the clutch cable pull too tight, I had real issues with my MZ as I could never find neutral 1-2-1-2-1-2-1 but I cured it by turning the lever reach dial down one so it didn't push the clutch in as much and it's cured, can find neutral every time first time.  Just a though.

@mjgt
The mighty gsx1400 has a hydraulic clutch no cables involved
:onya:

Your quite right  :whatever: my mistake but so has my MZ and the span adjuster solved my neutral problem.  Seems it was pushing the clutch push rod too far.

My Kawasaki MeanStreak had a neutral finder which was brilliant - it also had what I thought were faulty indicators as they kept turning them selves off until I read the handbook (who ever reads those?) and they had auto cancel after bike upright for 50 yards _ it was 2 years before I realised Duh  :bugga:

The span adjuster on the standard clutch lever just alters the rake of the clutch lever itself, not how much the clutch actuates - so whilst what you say is true where a cable is involved, given (as Notty and others have said) it's a hydraulic clutch, unlikely to be clutch lever.

Having said that your post prompted me to think of another possibility in that the clutch lever (and the small brass insert) may have dried out and want removing and greasing (if it has dried then the fluid won't actuate the clutch as it would normally, thus not pushing the clutch rod in far enough - which could cause the issue).

@VladTepes - maybe a quick additional check - remove clutch lever and brass insert, re-grease and re-assemble.

I thought that was normal.
Does anyone know how to stop finding neutral at 5000rpm and the occasional wandering neutral up between 4th & 5th?
Title: Re: Difficulty finding neutral

Just shift a bit more 'positively'.  If it continues to happen, try adjusting the gear lever down a bit - closer to your boot.

I think the false neutral is mostly caused (barring mechanical issues) by a 'light' upshift - not quite going the full distance, adjusting the lever down moves it closer to your boot & requires less movement from your foot to get the correct travel.

For more feel. Ride in bare feet or jandals  :facepalm: :facepalm:

@gsxbarmy @Kiwifruit @seth Thank you. Looks as if I'll need to find the relevant section in the workshop manual to make sense of that !  :)

No but if you send me yours, I'll try 'em if it'll help.  :whistling:

Too fast? No mate, shifting slowly, in attempt to find neutral.
Oil cold? In an Aussie summer?   :happy1:

Isn't a false neutral when its shows a neutral light, but isn't?

This is an actual difficulty in getting the box into neutral at times.

Mike,  this reply was for Taniwha, it follows his question but it's on a new page.

I understood a false neutral was getting the gear change 'stuck' between gear selection, so that you end up without any gear at all, the engine revs soon let ya know though . . .   bit of a flick upwards & you're off again.  No neutral light comes up - red face does though, much the same as reaching for 7th.

Post by: grog on Tuesday, 15 January 2019, 07:18 PM
Vlad, not about false neutrals, just finding real neutral, correct? Any prob with motor off? If ok with motor off, clutch is dragging. Simple.

Not sure - seems to be working OK again. If it recurs I'll see if there's a difference between engine off or running.

Do you use semi-synthetic or fully synthetic oil?
That happened with cold or hot engine?

Semi
Hot

Crap clutch action causing it to be hard to find N & clutch slip when first riding off on mine was the first sign that the slave cylinder was caked up with crud. Cleaning it out fixed it.
