clutch / brake fluid for a M 750 i replaced what was in there with putoline fluid and the clutch feels too light and i have difficulty getting neutral, though that could be the engine oil that i used, that was putoline as well - i cant find a supplier of rock oil down here in the darkest depths of Devon, which is what i have been using and getting along fine with.

Could you get neutral ok before? Is it better/worse with the engine hot or cold? Does it go in easy if you are rolling foward slightly? If you have an adjustable lever put it on the widest span and try again. If neutral is easier then try bleeding the slave cylinder again. I think the make of fluid is irrelevant as long as it is dot 4. I use Wilkinsons own brand without any problems at all. Other causes can be tickover to high, warped plates, lever span to small.

Have you tried bleeding it again? as they can be a right so-and-so to get all the air out & your symptom sounds lke air in there still.
Putoline is fine to use.

will try bleeding it again though this will be the 3rd time , it does go into neutral easier if the bike is hot or rolling slightly forward,

That would say to me that either the plates are not seperating enough/sticking together or they are warped.
I did have the plates sticking together problem on a 1200 bandit some years ago. All down to the oil the previous owner had been using. Oil change and clean plates cured it. However i think the bleeding issue should be resolved first.

If yours is the engine type with a seperate slave cylinder try holding it as high as possible when bleeding, but make sure you don't pop the cylinder out.

i was told about worn clutches sticking.. there is an adjuster onthe clutch with a pinch nut on it.. havent had to do it. but it takes up the play in the clutch and gives the same symptoms as a clutch with air in the line...

I stand to be corrected but i have never seen this nut and bolt you talk of.

Not on the M750 anyway. BTW it was a complete clutch plate pack(drivers & driven) that i replaced so there should not be any warping issues, but worth a look. the oil could be to blame, as i said i used to use rock oil semi synth but could not find a supplier when i moved down here, so had to go for putoline which i have not heard of before now.

Ditto to this. Check easy / cheap first, then go looking for the more complex stuff next.

If it was fine until you changed the fluid and then this issue started then it's very likely probs gonna be the fluid.

Have you checked the obvious like the fluid is new? It's not been open to atmosphere in a damp garage? Your letting it settle for a good 24 hours and not shaking it prior to use?

Is your clutch line a bit mucky / full off dirt particles? It might take a full bottle of new fluid to clean it right out if it's bad or old.

Best of luck.

Not on the dry clutch . Your Harley mechanic should stick to tractors.

oooooooooh put your claws away tiger.

Ive had the dry clutch on my 748 apart more times than i can remember, no adjustng nut/bolt.
Same goes for Louise's M750 & M600 (wet clutch & internal slave) and my 620 DD bike (wet clutch & external slave), no adjustng nut/bolt

I would'nt go on a Harley forum and quote Ducati mechanics opinion.

Like i said, stick to tractors. LOL

Just plates and springs and spring caps and bolts. Maybe your getting them confused. You dont want to slacken them off. Just remove 2 if you want a lighter clutch when you break one off like me :hissy::(:)

ducati and harley are the same company..... and i did only say i was told.. so maybe not then.. but all the same.. ill gave a look. i dont doubt what your saying..i looked at the parts fisch and there is no adjuster there either.. which makes sense as having a hydraulic line makes it self adjusting anyway....

No worries,
If you lean the bike over far enough to the left you don't need to drain the engine oil when removing the clutch casing, unless the oil is the problem of course.
If it was mine. Strip, check and clean the plates would be a definite. Also remember not to over tighten the pressure plate spring retaining bolts as they are easily stripped.

To be honest how can anyone not like this, even me.

mine isnt a clutch plate problem.. i just need to service it the bike.. hence the oil change.. my actuator is sucking air in i think .. replacement one arrived today so i got a busy week ahead...
