Hello Beat ,
hydraulic brake , hydraulic clutch , hydraulic start .....
But have you finished your physical training for Wohlen ?
We expect Beat 's team at the top 5 with the B68 Monster this year
Good luck

hi Francoise,

well, physicaly I should be a little bit better in form than last year, but again , we can not do any trainings before the race, because all training tracks are closed for wintertime here around.

for this year, I just hope to be more " on the track " with my brain then " on the frame " ore " inside the engine "

Top 5 isn't realistic on this week end because all are young teams with modern bikes, - our BSA will be the only classic machine and Beat is surely the
only 70 + rider in the Lot

Obviously one of your typical simple and straightforward modifications, beat!
I've still no idea!

You act on the hydraulic clutch and you brake with the rear pedal ?

beat · Post by **beat** » Mon Mar 13, 2023 9:46 pm

hi gentlemans,

the resolution of this riddle is:

a clutch automatic in correspondence to the rear brake

ore in other words : a anti engine stalling device ( so I can anytime fully activate the rear brake without pulling the clutch lever at the left side handlebar AND WITOUT stalling the engine

it may sound very simple , - just bring one other cable over to the clutch, operated by the rear brake pedal - and this is it

BUT, it is a bit more tricky as it seams by the first view...

because MY demand is : by using the rear brake, the clutch needs to be disengaged FIRST by around 80% before the rear brake is started to be activated!

as both parts, the brake and the clutch are " slipping " devices, - it can be a short time where both are still partly engaged / disengaged .
shurely, it needs to be adjustable, - when clutch gos out and brake comes in.

but, the demand of the clutch is, as the cable can not make more travel than let say 15 mm maximum !
and the demand of the rear brake pedal is as, it will make not more and not less travel then let say 60 mm !

the true is : IT WAS NOT A PICE OF CAKE

started with the clutch cable, as I do use this Triumph clutch activator

: the dotted line shows where the cable gos..

it is a excellent thing, working perfect, but needs to be correctly adjusted and sets the demand as its short lever should not be pulled to much, - other ways it is "snapping" over.

so I was building a " BRIDGE " above the gearbox with a additional lever, to make possible as two cables are pulling the one wich is going in to the gearbox, activating the clutch.

end stage: two cables pulling the additional lever wich is pulling the cable that gos in to the gearbox

so far for today...

It reminds me of this

As I've mentioned before, I can't stand that Truimph style 'ball and ramp' clutch activation mechanism. The 'clack' noise of the balls dropping back down the ramp every time I use the clutch on my A65 drives me mad. Trying to adjust the clutch pushrod when one end hits the strongly sprung pressure plate and the other end hits the lightly sprung ramp return spring seems a bit of a lottery. I prefer the good old solid rack and pinion method on my B44!

Cheers

Ian

Hi beat

Could you not have devised something to go in through the primary case and pull, rather than push, the pressure plate to disengage the clutch? This could be activated by the brake pedal which is in the perfect place, right next to the primary case.

I'm sure you could fabricate a prototype in an afternoon!

Cheers

Ian

IMO : as usual from BMW : a very simply solution for a extremely complicated process ....

to pull the clutch just next to the break pedal is a to easy solution for such a high tech racer, -- it needs a bit something more I think...

BTW, I am pretty sure you have been missing something with this " ball and ramp" thingy Ian.
in my case it is working realy good, - won't miss it on my bike

beat · Post by **beat** » Wed Mar 15, 2023 9:59 pm

now the left side with the break pedal :

the break pedal is pulling a cable indirectly, because a pre- loadet spring is in there to be able to give more way for the pedal when cluch is already finally activated.
also the longer lever is set in a different position to the shorter one to get near the dead end when the break pedal is making still more way just for the break and no more way is needed for the clutch.

VERY SIMPLY; - ISN?T IT

and today, I have tested it : gents, IT IS WORKING

out of nothing, I can get in to the rear break as quick ore strong as I ever wanted - and the engine is NOT stalling

Ok Beat so when i got you right , each time you brake , the clutch is activated as well ?
Don´t you like or need engine braking ?

Ha !!
sure I like engine braking , and I still have it !

I just do NOT having engine braking AND pedal braking in the same time together !

this is a - ( minus ) point of it, and I have to see how I get used on it.

will surely report after the race weekend on the Sunday 26. 03 2023
