Yep its normal for the KAAZ not to chatter when cold. I believe the oil is too thick for the clutch plates to function correctly.
My 1.5 chatters to all buggery once hot. First time passengers think a wheel has fallen off or something!
I will be adding some of the Redline LSD additive to quiet it down a bit because my car is primary a streeter, not a track warrior. The additive makes the oil a bit more slippery, and thus the clutch plates don't grip as easily.
