[QUOTE="HaulinAshe, post: 725779, member: 1875"] Well I finally succumbed to temptation and read this thread. Interesting... Pre-soaking the fiber plates of a new clutch in engine oil BEFORE installation, is Wet Clutch Installation #101. Sounds like Yamaha may indeed have failed to even show up for class on some bikes. It could also have to do with how the bike was ridden during the first few hundred miles. If the transmission was not shifted often through the entire gear range, but instead was ridden for long durations in a single gear (or higher gears), the assembly "gunk" could have hardened from heat/time and prohibited oil from penetrating between the plates as designed. For those doing the Disassemble & Soak, you can do all sorts of things to the clutch behavior by changing the surface of the metal plates. Wire brushing, ScotchBrite pad, Glass Bead Sandblasting (lightly!), or just general scrubbing all produce different release and engage characteristics. Have fun and enjoy! :) [/QUOTE]
