a couple of years ago, there was a video clip and a set of sequential stills showing Rossi adjusting his brake with one of those while heading out of one corner and into another at speed - dealing with an adjustment while in the middle of racing at the limit.

My vote is for front brake adjuster. Bit hard to take the right hand off to adjust things I guess. I read a while ago the adjuster on the left is normally for front brake.

It is almost certainly the front brake adjuster. As the pads wear down though the race, they have to adjust the pads inward to maintain the same lever travel.

I wonder why as soon as he left and entered pitlane he shifted all the way up to 6th and back down again!

Honda had an engine failure on Danis bike yesterday and sent the engine to Japan for analysis. They did not get out on track until they had an ok from the factory and when that came it was pouring down. Akiyoshi will a shake down test ride today and tomorrow all Honda riders will be out.
Unfortunately for them the weather forecast is bad for tomorrow as well with rain expected..

With hydraulics shouldn't that be automatic? I read that the brakes suffered fade and needed more lever to evercome it.

This have been on the top flight bikes for years. How would hydraulics auto adjust?

Probably right, and maybe it's a new donk / gear box setting... so he was checking all the gears are there and functioning etc...? Could be the new gear shift can need adjusting and he was checking the feel of it? Just thoughts.

Fluid displacement... like normal hydraulic braking systems? Doesn't the fluid from the M/C res fill the area behind the caliper piston when it moves out further? It seems to on every other hydraulic brake I've seen. edit: It's normally only the seals that hold the caliper pistons in position. Unless I've totally miss understood how hydraulic brakes function. Do they have a spring return on the caliper pistons? That would account for it.

From the Brembo site...
Remote Adjusters for Radial Master Cylinders - Remote adjusters are devices to allow a rider to adjust their brake lever using their left hand, as opposed to manipulating the master cylinder directly on the right side. This allows racers to adjust their brake levers for brake fade while riding. Brembo Remote Adjusters are the perfect compliment for a Brembo Radial Master Cylinder.

on another note
whoever made CS start a twitter account is a genius.
He is on there having a joke and a laugh with all the guys. he is coming across as a fun aussie bloke.
not quite the way most see him.
but than again the whole twitter thing might be his idea. with his wife and kid at home for most of this year he may now have the time to do it

The twitter debate between the riders is actually quite funny, seems CS and CE don't mind giving Spies a hard time.
Crutchlow was the winner though when he said that CE doesn't need to worry about riding in the rain 'cause his bike only has 200hp :lol:

For me that is quite mind blowing. He is actually adjusting the brake lever while overtaking in a race while going in to Doohan cCorner att Philip Island! :o

Anyone know what the little black thing is protruding above and to the right of the pit lane limiter switch?

Given some time to actually think about it, that makes sense. I'm really not sure where in my ass I got the pad wear idea.

Seems the riders have settled into the twitter thing. Between them and Yamaha and HRC, following the tests has been far more entertaining than the events would suggest.

Ben Spies
1st
“Today went well, the rain caught us out again but we got everything we needed to do done before lunch including some different chassis set ups and some electronics which we were pretty happy with. The rain started to come down so we waited until it subsided a little bit but with still a full wet track with standing water which we needed. We haven’t ridden the thousand in the rain and I’ve never ridden this track in the rain so it was good to get some laps in. I had quite a good feeling with the bike in the rain; straight away it felt pretty good so we rode in full wet conditions and stayed on wets when it dried out a little and was greasy. We’ve got a lot of stuff to do tomorrow so we’re hoping for a dry day!”

Jorge Lorenzo
2nd
“Today we improved a little the connection with the throttle and the engine, it’s much smoother and easier to ride, a big step forward from yesterday. We were able to try the 1000cc M1 on the wet for the first time and we went very fast so it’s been a positive day and we are very motivated to improve the bike more. We managed to complete everything we wanted to test so it’s been good!”

A good time to " improved a little the connection with the throttle and the engine"! Wet riding on a 100GP bike would be quite a task.

Matthew Birt ‏ @birtymotogp

Lorenzo and Spies both told MCN 2nite that Yamaha has cut gap to Honda with new 1000. But both said: "We hope it is enough."


Matthew Birt ‏ @birtymotogp

Lorenzo has had new electronics, new engine and 2moro a new chassis to try. Yamaha working incredibly hard to win back title


What I'm left wondering is ---- have they (Yamaha) cut the gap to what Honda had done the day before??
--------- and if Honda hadn't taken the day off because of the engine problems would that gap have stretched back out somewhat!
I believe I'm growing sceptical of cynicism!

Quote from the front page of MTM...

Valentino Rossi (Ducati Team) 7th, 2:02.130 (18 laps)

“Another day practically lost, which is really a shame because for us it’s very important to ride as much as possible, and today's track conditions were much better than yesterday's. Given that we knew rain was predicted for the afternoon, we tried to focus as much work as possible in just the first twenty or so laps this morning. Using both bikes, we tried the new traction control, some software updates with the wheelie control and other small details that have to do with the seating position. I had good impressions with all of those, so we put it all into the setup of just one bike and put on a new tyre, only for it to start raining. Game over. On the plus side, I had a good feeling with all of the new stuff, so I hope we can work a little longer tomorrow.”


Is the reason for having the new things spread across 2 bikes to enable them to trouble shoot easier should one of the "new things" not be effective?

Is Hayden simply testing the bike, whereas Rossi is trying new things? Could this explain the fact Rossi is 4 tenths slower? However much I like Nicky, he's not normally as quick as Rossi... so I would be surprised if there wasn't some 'factor' behind this. Especially as Nicky is recovering from injury still.

This is pure specualtion, but Rossi is normally a couple of tenths quicker than Nicky, which would actually put him right in amongst the Yamaha's... I remain hopeful.

Fingers crossed that the rain stays away for tomorrow, the we get some Honda's on the track and we can come to some very preliminary conclusions coming out of Sepang II, rather than just teams not able to complete the testing they aimed to do.
