1. Bleeding the clutch system:
I'm a bit baffled here. I noticed the clutch fluid on my '92 907 appears contaminated so I got ready to flush and refill, to my surprise, I cannot find a bleeder screw anywhere on the bike.
There is a aftermarket slave unit (STM) and then there's the braided line from the reservoir to the unit, no fittings just the regular "banjo" fittings at both ends.

2. Rear brake switch removal:
I need to remove/change the rear brake switch ('92 907) it goes "thru" the rear hose "banjo" fitting so if I remove it I'll have a mess and have to refill/bleed the system? or is the switch independent of this fitting?

Help!! Many thanks!!

1) best location to bleed clutch is both banjo bolt on pump and clutch slave, placed close to generator on left engine cover.
2) any hidraulic brake requires bleeding. About rear brake pump, I can tell you that the best place to bleed is hydraulic switch! so...
HAVE A NICE WORK, and...

Mmmm ...so you bleed these by loosening the "banjo" fittings? no bleeder screws? ...imteresting (as the rest of the bike...8])

Regarding the brake switch I understand then that it CANOOT be removed without "opening" the brake system which will then have to be bled, correct?

Thanks for your reply and assistance!

Simply: AIR is going UP from system, never down, so You have to find highest place to take air away. Sometimes it means, that U have to take some parts out of they places and let them "overnight" to such position, that all air is in highest place and then open just that place and let air out.... no matter, is it banjo bolt, or whatever..... Thats why i allways change such liquids from down to up!!! Then never problems with air bubbles in liquid. Also, if system have been totally open, then its much better to start fill up system from down to up....little by little, cause time make nice things here... U can even take some beers meanwhile waiting! .... I know, that if there stays some air in system, then let main sylinder overninght to such position, that banjo is in highest place and open it carefully next day and feed air out.... its quite simple, when thinking, where air wants to go in system... Another method is to take main sylinder out of its place and hang it overninght to such position, that main sylinder is in highest place and next morning very softly/fastly with small movements pump main sylinder very many times. That takes air from liquid to main sylinder canister... fucntion, like "trains toilet"

"interesting" procedures to say the least ...
thank you guys for all your help, much appreciated and needed!! ...

Cyber, would you please put a smaller image in your signature? My "low profile" internet connection should be very happy for this!

the only reliable way to bleed any fluid system is from the bottom up,and that takes some poking and tapping and getting your gloved hand dirty

ducpaso ...done, sorry about the bandwidth hijacking ..

hig ....yep, that's the way to go ...maybe James can hold my silver spoon in the meantime ....
