Jolt into 1st Gear - Clutch not disengaging?

[jimbo]

When stationary, selecting 1st on my 2013 LC give a good 'graunch' and the bike lurches against the brakes.

"They all or that sir" or fault?


Oh and I pressure washed off the sticker showing the position of the tyre pressure monitor - when will I regret it?

Well the demo bike of that year I rode certainly did it. The change through the rest of the gears was equally poor.

My 2013 did that but so does my 2015 although maybe not as bad!

Tyre pressure stickers, just remember to mention the sensors any time you have tyres changed.

Yes they all do it to some degree or other, best to change down to first when still rolling & hold on the clutch to avoid embarrassing graunches. poor on an expensive bike but don't let it spoil the bike for you

Yes they all do that, the degree of 'clonk' varies with how hot the engine is - my 2013 bike would slot in silently when stone cold but clonk when hot, my 2015 bike is pretty much the same.

Was on a trip this year with a group and one guy had a Kawa 1000SX, crunched and lurched in the same manner as my GS when selecting 1st.

I really don't understand how any manufacturer can say that this is normal. As Im not very mechanical, can someone explain what happens to make the gear selector so 'clonky'?

If I bought a car and it made that noise every time I selected 1st I would take it back to the dealer. I just don't get it? I have has plenty of bikes and most of them had pretty sweet gearboxes. So how come some bikes 'clonk' and some don't and why, with all the modern electronics, isn't this a fixable issue.

On my 2014 GSA if I use my GSAP (which now works!) it slips through the gears without any problems but if I use the clutch then the gears crunch? Im confused, which is pretty normal for me..

It's a wet clutch, that's why it does it. You open the clutch you still have the drag of the oil between the plates, gear shaft is still spinning so you get a jolt. Every bike I have owned with a wet clutch has done it to some degree. It didn't do it on the older bikes because they were a dry clutch like a car so the gearbox completely stopped with clutch pulled. The problem with that was sometimes you couldn't select 1st if the box stopped in the wrong place. The solution was to let the bike role or slightly engage the clutch resulting in a clonk.

 

[jimbo]

Its not the first bike, I've had with a wet clutch, but none others made the bike jump like my gs does.

as a matter of interest, anybody know why bmw moved from dry to wet? Does the multiplate design need a lower clamping pressure, so lighter on the fingers?

Clutch drag - cars have dry clutches so very little or no drag - we have been through this a gazillion times before; however I think it might also be aggravated a little by the clutch design, it is self-energising (to make the action very light) and it is also a slipper clutch (back torque limiter)

They chose an engine layout that wouldn't allow a dry clutch. Integrated gearbox and all that which was probably dictated by weight saving, rotational mass and total length of engine and gearbox. Plus side it's a hell of a lot easier and cheaper to do the clutch. No idea if you could incorporate a slipper clutch into a dry setup either.

OO self energised? that was enough to make me go searching. look what I found- the clutch is at the wrong end of the engine

there are adverts for a dry slipper clutch of various Ducatii, so its looks like you can.

They're clutches, Jim, but not as you know it.

The Duc' dry clutches are multi-plate, just no oil. Have you heard the row they make when disengaged?

Jimbo - my 2013 used to clunk into first, neutral was hard to find sometimes and occasionally felt like it was dragging. Dealer replaced clutch under warranty and I've had no problems at all since. Same thing also reported by another gentleman of this Parrish who also had clutch replaced (clutch basket was slightly mis-aligned apparently) and his bike has now done over 50k miles with no further issues!

I think the grey area here. Some clunk into first is expected - but at some point it becomes excessive. My view is that my bike is towards the "excessive" end of the spectrum, certainly more than other wet clutched biked I've owned. Time to take a ride to the dealer and ask their opinion I think.

Many owners have had their clutch packs replaced under warranty (warped plates) I had more serious gear selection issues & was lucky enough to have a full engine & gearbox swap out under warranty at about 5.5k miles. Persevere, when its sorted it will be a good machine. The dealers are usually good after the first denial visit, if you get stuck, email the UK service director - he sorted my case out super quick - you will find his mail on the forum if you need it. Good luck

The WC GS is an absolute stonking motorcycle in so many ways. Sadly the clutch/gearbox is not one of those ways. I've now ridden over 10 WC GS's and everyone of them had a very poor gear change between 1st and 3rd.

On one bike I rode at the owners insistence, you could hear the clonk from the gear box as he went from 1st to 2nd whilst riding behind him.
He insisted the change was fine.

Real shame, otherwise a cracking bike.

 

[jimbo]

hmm
so engine warm through, on the centre stand, Clutch in followed by a good pause, then into first. wheel moved and the stops.
I'm starting to think 'Feature' rather than fault
