A few folk have commented about occasionally getting loudish clacks from the gearbox when changing gear. This seems to be caused by part of the change mechanism hitting its travel stop at the end of each stroke.

An effective cure is to prevent this stop being reached, or at least to significantly reduce the impact force in play when it is reached. This is done by limiting your foot movement to no more than just the distance needed in order to change the ratio rather than, as is a common occurrence, of using much greater movement and force than is needed. But how much force and movement is necessary? A good guide is: instead of applying the movement and effort you habitually apply in order to change gear... reduce both to that needed to find a false neutral between the gear you are moving out of and the gear you are looking for. A smidge of pre-load on the lever makes things easier. There seem not to be any false neutrals so this is ok to do.

By doing this, and by using full clutch lever travel, from setting 4 if you can reach, I quickly achieved more than 90% success rate of silent or near silent changes both up and down and I have expectations of reaching close to 100%. The knack is easier to acquire in road and dynamic modes than in the rain setting as, in my case anyway, rev sync is easier to time accurately.

Although it may take some folk longer than others, It does not take too long to reprogram your muscle memory to the state when everything becomes automatic, it’s almost like going through the same process as changing from BMW’s much missed, by some anyway, 3 button indicator system to the new 1 button switch.

It works beautifully for me, good luck to all who persist until they have it cracked.

If the clutch has fully disengaged within 30% of it's total travel capability which it should have,why on earth would you take it right back to the bars :nenau

Masochism, he only uses two fingers on the lever and just loves the repeated pain of changes.....
 
I found a lot of false neutrals on my test ride!:confused:

I put it down to not using enough clutch movement, and the problem I had squeezing my boot between the gear lever/pedal and the side stand spigot when up shifting. That was my only real problem.
 
I'll try it tomorrow on the Ocean Fish and Chip Run to North Tawton. The weather forecast is torrential rain on Dartmoor during the run but since I've now got a GS I suppose I still have to go?

An effective cure is to learn to ride

That's it mate, do the run or buy an RT and stop at home :thumb :D
 
Agree. Presetting some pressure up on the gear lever is paramount. So are using very little clutch in and very little cut-off on the throttle grip. The keys here are small and quick, not big and slow.
 
What a load of crap, to ride this all singing, all dancing, amazing WC, you have to change your riding style to stop the noises, better it was built without the noises in the first place.

I think that it's some of the more "senior" riders, as they tend to hear funny noises regularly.:D:hide

I've not heard any noises from the bike, just the voices in my head.:augie:D

it's only a noise, anyway apart from going into first at a standstill gear mine doesn't clack - so I either have one of the 'good bikes' and you lot have Friday afternoon ones or I have just learned how to change gear properly :D

I swopped a 1600GT for a late 1200GSA (best thing ever) however, there is tonnes of this banter on the K1600 forum, and much advice on the why's and wherefore's, whether the Clack or Lash is real or imagined, answers and highbrow theories from those in the know or with the know how, and a smattering of smugness from those with a Jedi sensitivity to the fly by wire, or a Altberg shod left foot capable of stroking a sleeping Pitbull's scrotum without protest. Aarrrggh!! This is the real world, most of us here have been riding a few years, and are capable of adjusting how we ride different bikes and enjoy the challenge of how to get the best out of a particular machine, don't we? Do we need to evolve or have the bikes gone too far technically speaking for Old Skool Tossers to manage.

and phrase of the week is definitely;
