Anyone had this? Disengaging clutch?

[Mark Hooton]

Guys, I have just read TJD`s post on the failure of the swingarm and as most of us have expressed - TF he is ok. Thats a shocking failure and I hope he gets to the bottom of it.

I wasn`t going to post anything as I suspect `me` doing something wrong here but has anyone experienced the following?

Whilst riding, the bike seems to momentarily slip out of gear then re-engage!!!!!

It`s happened 2-3 times now. I suspected `me` at first - i.e. head up ar*e, thinking about everything but riding and the bike and not knowing that I was pulling the clutch lever out then letting go

After reading the post by TJD I could be forgiven for getting slightly paranoid over our beloved 12`s so I thought I`d ask if anyone else had experienced this?

This last happened to me this morning and got quite close to an `off` - could it be me not selecting the gear `positively`?

Any guys got any suggestions? (apart from buy an 1150 and all of those posts..........)

Regards,

Mark.

if you have a 2010> bike it might be a failure to engage gear correctly. normally when a gear isn't quite selected fully it jumps into a false neutral. these later gearboxes don't seem to have any, so if it slips out of gear, it either jumps back in again, or to the one below.

unlike any bike gearbox i've ever encountered, the engagement of the gears is spring loaded in some way.

Thanks mate - it is a 2010 and rather than stay in the `false neutral` seems to jump back in - this makes me feel somewhat better as I am suspecting its me not engaging the gear properly.

lets see if any other tossers have owt to say..............

I've had the same issue on my 2010. Thought I had a clutch problem. Dealer checked it over and reckoned the clutch was fine but that if the gear wasn't positively engaged they have been known to jump out of gear and back in. Seems a bizarre explanation to me

Do you get a burst of revs, a little flash from the traction control led, and then everything back to normal? - I think I've had it exactly once on a dry straight road in 4th accelerating. I'd been in gear for a few seconds. I guess 2500 miles or so is a bit early for a clutch slip.

iv done this a few times as well altho i know its user error slightly moving my foot (yes i have huge feet and a small gear switch!) up at the wrong moment and it shifts the gears either up or into a neutral part between gears.

nout to worry about just think where your feet are next tome it happens

Done this .......... my fault.

I had a case many years ago with a K100RS, and the solution was very simple, where the clutch arm pulled back at the cable, a piece of grit, a small stone got locked inside the clutch arm, so the clutch could not re- engage fully as I changed gear, but as we pulled the clutch in a couple of time it cleared, but it seemed very strange till I understood why. One minute the bike is perfect, then ten seconds later you get the equivalent of a false neutral.

May not be related but but worth a check just to see if the clutch arm at the cable connection is not excessively gritty?

Aha! So I am not imagining it!

Yes, thats exactly what happens but its looking like its down to that `not engaging the gear` properly.

I`d be careful mate, it has all the potential for an `off` especially if it happens around a bend.

 

[ianran]

Had this on several bikes from different manufacturers, bioliogical interface problem I believe

i hadn't considered traction control being involved as i don't have it

my 2004 gearbox sometimes drops back down a gear then up again,but i ride in motocross boots and im very lazy/clumsy with gear changes so it dont bother me,nearly every bike iv ever owned has had false neutrals or has jumped out off gear at one time or another,i think with bmw you have to be deliberate with gear changes,one thing to check would be the gear selector shaft where it passes through the frame these can seize as they are not lubricated very well from new.

Same 2011 ADV

Hi guys, mine does this too..
I'm sure it's my fault, but its very unnerving, it's done it from new & am living with it, i thought it would get better with age, but over 7k miles now it's no different, I am learning to be extra 'positive'. In my gear selection, it usually happens when u least want it to, like on a quick overtake after a sloppy gear change..
If anyone's got a solution let's be having it...

I've had this happen on the odd occasion on my 2010 RT, 2005 GS, 1999 1150GS and my 1995 1100GS. Everytime it has happened is down to me not engaging the gear correctly.

a good solution is to make sure you actually change gears correctly.... but who wants to do that!?

Select and engage gear correctly.... before entering bend

the weird thing is, the later gearboxes try and get it right even if you don't move the lever the full travel. you only have to nudge the lever, and it will put itself in gear, the mechanism won't just stop in neutral.

except when it doesn't, it jumps out and then back in.

personally, i think it's a rider timing issue.

 

[Sgt Bilco]

Bad rider gear selection and I do occasionally

 

[Mark Hooton]

Thanks to all

Thanks Guys, its fairly clear to me that its a problem with my left foot andf I thank everyone for their help and opinions

And it also sorts out my paranoia about my beloved 12..................

(still on my first FD and she`s done 7000 miles )

I've had this happen, but it's purely down to me.

Usually, Just as I change gear, I realise it's not quite in fully (the Mrs complains of this too, but that's another story). Just as I'm about to click back up again, it does the down 'n up thing on it's own.

Often this is down to poor chain tension...
