wrong clutch fluid DOH

[stanley]

That could only be true if the slave cylinder was actually inside the engine or gearbox. They never are !
On the 1150 I dismantled a few years ago it was linked by a pushrod and a couple of seals.
Your post sounded good , but it's incorrect.

My post is accurate if read properly.
My post opens with "Some bikes".....
Your comment, "They never are" is inaccurate: Many, many bikes have their clutch slave cylinders mounted on the gearbox (engine) housing.
OK, so R engines don't.... BMW may have continued to use mineral oil to be common with their contemporary range.

Whatever, I much prefer working on bikes that use mineral rather than brake fluid

If BMW had used a normal clutch and toroidal slave cylinder we would not have to worry about push rods or cleaning the slave cylinder. Parts costs would also be next to booger all.

Stanley , without being pedantic... I'm just curious from an engineering POV.
Can you give an example ?

KTMs have it worse....

The slave cylinders are poorly made; the o-ring piston seal fails; the fluid passes by this, along the pushrod tube, and into the engine/gearbox.
That's why so many have Oberon replacements!

Where do you live?
I could show you two in my garage (both KTMs btw)!
It's a known issue on many KTMs. Keeps Oberon in business though!
