Box juming gears

[zerocool]

Not had the GS long, found that the box jumps outta gear every now and again. Usually 2nd to neutral but occasionally 6th to 5th shortly after changing up.

Anybody else have these problems?

Funny thing is it happens pretty infrequently and I cant even force it to happen so im sure its just not my crap riding.

Sometimes if I'm knackered, I occasionally miss gears. I bought a gear extender from Nipy Normans, this improved the situation for me... I'm on an 1150. What's yours........it would help to know?

I've had this as well, normally when getting a move on and going through the box fairly quickly.
A few things you could try...
Check gear lever is tight on spline, a little slop will prevent full movement.
Allways use clutch from 5th to 6th and be very positive.

I've also found occasions where I've shifted into second and then found it wont change up into 3rd. Again when getting a move on and it's as though second has not fully engaged, allways changes up on next attempt - seems to be the removal of drive at first attempt is enough to get the gears to engage (probably the selector fork rather than the gears - I've not been inside a box for many years) and allow the change up.

Just to set your mind at rest, bikes been like this since I bought it second hand at 16,000 miles and its now done 85,000 in 3 years, not got any worse.

Hope this makes some sort of sense

Good advice burl, service tomorrow so ill see what they say. I mentioned it to the guy when I was booking it and he mentioned that it might just want adjusting a little but didnt suggest for a second that it could have been my technique which I thought was quite refreshing.

Gears.

I have had this problem often when wearing different footwear, I.E summer boots.

My 1150GS will jump out of 5th sometimes after an upchange from 4th or I will not cleanly select 2nd changing up from first. It's normally a combination of a snatched change along with a need to clean the gear lever pivot. It gets road crud in it and the change just gets a bit stiffer. I mention it to the dealer at service time (at least I did whilst it was still under warranty) and they cleaned/lubed it. No more trouble for a few thousand more miles.

Mine jumped out of sixth alot until somebody pointed out the pre-click technique (just made the name up but I'll explain). There is a small click between 5th and 6th. If you gently click upwards before you make the change it can help alot. I don't understand why it works but mine jumps out far less frequently, and usually when I forget to perform the aformentioned proceedure. It's a very delicate little nudge of the lever to get the pre click and they clutch in, good boot full and hey presto 6th gear.
Try it, might be bollox on yours but it works on mine.

Good advice, ill try that and let you know. Funny thing is I dont see it happening when im knackered as I was tonight. And I am wearing new boots so could be that but I cant remember it happening when I got them.

Can anybody describe where I should be looking to clean/lube this "crud" covered pivot?

I often clutchless change and never get this problem when doing that, only when clutching up.

Clutchless changes on the beemer is never a good idea. OK with jap stuff but the BM box is too agricultural. I think you'll cause yourself problems in the future. The gearbox is a bit of a weak point, mines been renewed with about 34k on the clock so best to treat it with a bit of care.

Hello Flipfly, I have that same little "pre-click" but on mine it's when I have changed up to 5th, it is a very distinctive 2 click change or one and a bit if you count the second click as being very small. If I don't get the two clicks that's when it can jump out of 5th. Sometimes I'll try and get 6th and just get the mini-click which completes the previous up change to 5th. The next attempt then changes cleanly into 6th.

That looks as clear as mud so I hope you follow what I'm explaining badly!

It's the pivot for the lever that you actually move with your foot.

My 1150GS handbook actually states that you should make clutchless upchanges but not down changes.

 

[Colban]

What oil do you use in your gearbox?.
I had similar problems to yours after a dealer service where they had changed the G/B oil.If cleaning the gearchange pivot doesn't work,try changing the oil (i use Silkolene).This fixed mine.

 

[Captain Beaky]

Mine's started doing the same too recently - but only with the really cold weather, when I'm very tired.

Couldn't make it happen again - it just happens when I'm not paying attention....

Ah well - seems like they all do it!!

My old 1150 did it for 7 years and 126000kms. I 'think' it happened when I shifted up gently to 6th and didn't vary the throttle position at all afterwards - I found that if I opened and closed the throttle slightly after changing up it didn't jump out of 6th. I'd guess it's to do with the load on the gear not being sufficient to keep it engaged, if that makes any sense

Ive tried both but I decided quickly that the GS box wasnt happy downchanging but it always seems more than happy upshifting.

How many people upshift and havnt cooked thier box???

Ill check the pivots and maybe the oil too, im not to sure about what they put in when it was serviced last.

Still cant feel the small click folk are mentioning.
