What else feels like clutch slip??

[Anonymous]

I have replaced both sets of plates and added a new clutch cable. I thought I could not get the clutch cable adjusted because it still felt like it was slipping. However, I have had a professional look at it and he made some minor adjustments and said the cable was perfect. I still have no power. Gs750 doing 70 mph in 5th gear at 7000 rpms. The engine sounds tight. What should I look for next??

Did you replace the clutch springs? They could be weak and not putting enough pressure on the plates. Did you soak your new fiber plates in oil before installation?

People say using oil with friction additives can cause the clutch to slip. read here.

It can, but how about the things I mentioned? Even with friction additives you would think the clutch would perform better than it is. Most slip occurs under hard acceleration. Under constant throttle it should grab unless something is wrong.

20w50 regular castrol motor oil, new heavy duty springs, soaked the fiber plates in oil over night, very lightly sanded the new metal plates with 100 grit sand paper then wiped clean. Even the mechanic I took it to as the last resort was a bit stumped .

I was hoping someone might say you know there is a 100 mile break in time and then it will start to grab wish ,,,,wish!!!!

Possibly dumb question, but are you sure the tach is reading right?

Maybe the 750's are like the 1100's. There are two different thicknesses of clutch plates. In I think it was "82" the 1100 4 valve engines increased the # of plates. I'm thinking they made the plates thinner so they would fit in the same space as the earlier models. If your 750 plates aren't the correct thickness, that could cause a problem.

My tach is reading right, at least from the sound of it, it is screaming at 8500, I thought about plate thickness too, I did order the sets (fiber and metal) that were listed as fitting my specific year and model. I did keep the old plates (metal) but if I tried to add it where would I ??? I start with a fiber and end with a fiber, could you end with metal??? I probably sound stupid but can I put an extra metal together with the last metal and then end with a fiber???

watching post carefully.. as I have some clutch slipage on my 83 750e
but havent replaced clutch yet...
one other thing I noted as a similariaty is the castrol oil... I used regular castrol as well (though I think I used 10/40)
please let me know if you do an oil change and it changes things...

As a final stand I was going to go down to a 10w 40 oil as on the case. I know that may sound like a witch hunt, and the 20w 50 is probably fine, but after this I am thinking it is a basket issue . Could something in the basket be worn and causing the slipping or the gears around it???

[Roseknight]

Sparks you gonna stick to regular oil or switch to a "motor-cycle" oil?

i've always used 20w50 Castrol in all my bikes, only time clutch slipped was when I put some Slick 50 in with it. Drained it out, went back with Castrol 20w50 and all was well again. I really don't remember how the extra plates were installed, but I think they did come up with metal to metal at one end.

What about the springs, that Billy asked about?

Chances are slim to none that oil is causing this. Castrol 20/50 and 10/40 are used by many on these boards.

springs are brand new, and I am not going to motorcycle oil as I don't think that will solve anything. I feel it really has to be another issue at this point but it is causing the clutch to slip on me or at least gives all the common symptoms of clutch slippage.
