2001 YZ426F I'm replacing replacing the friction plates as my clutch did not have any slip. I ordered a plate set from a local dealer. They are EBC Heavy Duty friction plates. My question is one of the nine plates has a narrower surface area than the other eight. I thought this was odd, but just thought I would pay attention to how the old plates were removed and install the new accordingly. However all nine of the old plates have the same amount of surface area. Should the narrow plate be basket side, pressure plate side, or some where in between. Has anyone ran across this before??? Also what is a proper soak time for the friction plates and can they soak for too long?
