A question about clutch plates

I've just replaced my clutch springs in the hope that it'd improve my acceleration, but, alas, not, so I'm about to replace the friction plates too, I read somewhere on here that they have to be soaked in oil before hand.

my question is, for how long? is overnight enough? 24 hours?
and if there's anything else i should be looking out for while i'm in there, lemme know. ie worn steel plates or whatever. I only have loan of a Haynes manual and they suck. right?

thanks guys

you really are a great help.

oh and which type of oil is best, I guess the same as is in the engine but i bin wrong before. Smiffy

all the best and thanks in advance

a couple hours is ok, overnight is better, on the steel plates lay them on a piece of glass should be flat, no waves or cupping.... engine oil is the clutch/tranny oil

www.biker.net has the Service Manual for 78 to 81, which will give the specs for the clutch plates etc.

For 78............ Friction Plates normal =.118" wear limit=.106"
Steel Plates normal = .055" no wear limit given

You probably know, but in case you don't; you should not use automotive type oil that has "energy conserving" or similar on the bottle. That type is just too slippery for these clutches. Use motorcycle oil or diesel oil.
