On all the onboard shots where you see the clutch lever I notice every rider has the clutch cable adjuster 'wrong'.

The lock nut is up against the cable end rather than the lever perch.

Anyone know why? I'm assuming it for adjustment on the fly?

Are they using the clutch? Not if you look and listen carefully. Less chance of cable snapping when they do use it if it's as you see it.

Of course they are. Maybe not for upshifts but they certainly do on downshifts.

Not on my tv. Downshift with no clutch pulled in. Watch again.

John McGuinness was saying something about this with the new Honda, how he was used to using the clutch (on downshifts) before riding this machine. I would have thought quick shifters/slipper clutches were fairly standard but maybe not (across the field).

It's more the autoblippers on most modern bikes now a slipper clutch still needs clutch on downshift. Anyone watching Moto 2 will know about the rider who won in mugello having front brake and clutch lever on the left hand bar and how he changes down gear

I don't think that it's a floating locknut. I think the adjuster is one piece and probably has a bit of sprung steel that engages with the "wheel" as a form of ratchet.

It's an adjuster for the front brake travel above the clutch lever. As the brake pads go down you adjust it to stop the front brake lever coming back to the bar.

OGR,
thanks for enabling me to tell Mrs K what it does to the brakes. OP means the actual adjuster for the clutch lever is wound out away from where it 'normally ' is.

If you watch Huttcy. You see he only used the clutch a couple of times. At start and at the finish (pit stop included) He also mentioned quick shifter.

As a bonus. He also has a rear brake ( thumb operated ) under the clutch. Which he was using one hell of a lot to keep front down and stop rear spinning up Thumbs Up

Not sure why but last night I was looking carefully at the on board shots from Hutchy's bikes, last night.
When he crossed the finishing line, to win the race, and was slowing down to get back into parc ferme, he went down the gears without the clutch, however he did use the clutch to get it down into 1st.

I bet the tyre technicians hate burnouts in the winners enclosure.

As a side note, assuming the BMW used a full tank of fuel over 2 laps, the bike's getting around 10 mpg!

Excuse my ignorance, but quick shifters and auto blippers?
is this just clutch-less shifting up and down?
does this mean that there's actually never any need to use the clutch?
or do you have to be in the right rev range when clicking up/down?

help me out :p

Quickshifters basically cut the throttle (bike under power) unloading the transmission and allowing a shift up without the clutch.
Autoblippers just give it a very quick pre-set rev or throttle blip (bike under deceleration/engine braking) unloading the transmission and allowing a down shift without clutch.

You still need a clutch to pull away and stop.

The tensioning spring against the adjuster ferule is plainly obvious.

Hmm I thought blipping was to help with rear stability (on an aggressive downshift).

That's the job of a slipper clutch or back-torque limiter.

I see what you are getting at, but blipping the throttle in that sense is for when you are using the clutch to change down. Auto blip works much faster than that.

thought it would take me while to get used to the quicksift on the new bike, now the clutch is just something for the traffic lights

So does the autoblipper wok in conjunction with a slipper clutch? Or instead of?

the extra adjuster on the left hand is for brakes.
so can adjust while still on the power with the right hand.
