Shadow1, how many miles were on the clutch at the time ? What synthetic oil did you put in it ? When you say cold, how cold was it ?

I just did the clutch on my 90 cbr same thing around 7 to 8 thousandrpm it would slip only when on it hard pulled it apart looked good.Fibers were fine steels wernt glazed .I redid it with a barnettkevlar set also when i checked the springs they were about 3 eights off in height leading me to belive i just had weak springs.But i can feel the difference in the way she screams now .by the way what do you guys torque the springs to i thought it was 6 or 9 ftlbs i went with 9 ftlbs
I think it's 7 ft lbs if my write is correct

Edit: I'm looking through my clutch write-up and half of it is missing...what gives admins?

Synthetic oil will make a clutch slip.
I beg to differ. Synthetic oil in and of itself will not make the clutch slip. I've used synthetic oil for 25K miles and she still pulls strong to 160mph with no slippage. Yes, you can put the wrong oil into the bike and cause problems with the clutch slipping. But to make a general statement that synthetics cause the clutch to slip is not entirely accurate.

Not throwing stones TBT, just a difference of opinion.
98% of what I wrote get lost.

I just found this thread having searched the www as I'm getting slippage on my 1996 CBR1000FT. Seams funny the way it feels when it slips? I think I'll change the hydraulics first....

Usinf synthetic is no problem as long as you are not using a synsthetic that is made for cars. I use hypertech 20W50 for bikes and no problems, my bike is at 147500kms

I remember some motor oils contained graphite or molybdenum. The graphite and moly would coat the clutch plates making them slip. But I think that was several decades ago. The "energy conserving" oils of today also have an additive that can coat clutch plates.

Sneaky; What's the bike's history? What I mean is, have you just bought it?

Worn plates or the use of car oils are the main causes for wet clutches to slip. Rule these out first mate.

I was going to buy some friction plates then strip the clutch. Having read above I may just change the fluid then suck it and see, a fluid change wont hurt...it was serviced about 6mths back and poss they did it? I bought the bike a year ago with 60k miles on it. Its now at 65k!

In general, most shops won't change fluids unless asked, they will just top them off if low.
