hi guys , i went out to matlock last weekend and found i was loosing pressure in my clutch lever! the clutch its self feels fine the bike torquie as hell its not slipping at all, so when i got home took the res cap off to find the fluid is black? Ive been using DOT fluid not sure if it is correct spec for the bike? anyway i cracked the bleed nipple off at the cylinder near the gear lever put on a pipe and put it in a tub a brake fluid and started to pump away i soon realized that the res on the clutch lever was not going down! so i locked off the bleed nipple on the master cylinder, and found i lost all pressure in the lever. so Ive tried to bleed the clutch lever up at the bleed nipple on the lever and the handle bars and i cant get any fluid up whats so ever can anyone help please its pissing me right of at the moment:frown:

have you tried the two syringe method, bleed from the bottom up

fluid should be oil Not the normal clutch fluid. the system is made to run on mineral oil so this could be your problem. 2nd the piston in the slave cylinder is know to go wrong (stick). if you have been using the wrong fluid this may be balls up now(seals failed). if it is upgrade to.

Mineral oil should be used.
Other stuff is prone to fucking the Magura seals.

Putoline mineral hydraulic clutch fluid £4 for 100ml. you may get away with just the 100ml if your careful or buy 2 just to make sure. Thinking about it your gonna need to flush some through to clean it out. get 2. better hope the master cylinder seals on the lever are not fooked too, those are 2 or 3x the price of the slave. could end being a very expensive lesson. don't do the same with the brake fluid, it may not end in the same way.

Next time you need clutch fluid get some of this ...

Carlube ATF-G Automatic Transmission Fluid 500ml

... does exactly the same job as the Motorex / Magura stuff without having to pay through the nose for it
