potential clutch and transmission problem?

Had two things happen recently that cause me to question?
First, while my bike (2006 with 10k miles) was in the shop for a tire
change the mechanic (going over it in general) commented that the
clutch plates looked too brown and seemed to have "crystalized". I
never heard of such a thing, but he said it can happen from too much
heat or running with too little oil (which it never has). Am I
getting a load of bull?
Second, tranny just started giving me a "thunk" when going from first
to second. Doesn't seem to miss gears -- and all other gears seem
fine -- but I really hate new noises.
Any ideas?

Don't trust those dealer mechanics. They are trying to keep their
doors open ..... and may sometimes not be honest. learn to check
things yourself or get involved with groups that have tech days.

How did the mechanic get a view of the clutch while changing a tire?
From the oil hole? I can't imagine he took off the side case, and if
he didn't, he didn't see much of the clutch. KLR's have pretty rugged
clutches and 10k miles is nothing unless you've been slipping it like
crazy at the drag strip or getting stuck in mud/sand a lot. What kind
of riding do you do?
I'd say if it works fine, leave it alone and take a close look at your
oil and oil filter when you change it. You can test it by putting the
bike in 5th at 25-30mph or so and gassing it. If the motor revs
without much more forward motion, it's slipping; if the bike
accelerates or stumbles or stalls, the connection between the tranny
and the wheel (the clutch) is good.
The first/second gear clunk can be as simple to fix as
tightening/lubing the drive chain, topping up the oil, or changing the
oil.

Huh? My clutch plates, when I look in through the top, look brown too.
And have looked brown for the past 20,000 miles. My clutch works fine,
BTW.

It is normal for a KLR tranny to go "thunk" from first to second, this
is somewhat oil dependent (it happens more with thicker oils that
interfere with the action of the syncros). Did you change the type or
viscosity of oil that you use recently?

Beware of mechanics changing tires and looking for something else to charge you for.
Clutches come in the box brown in color

My clutch friction plates were brown coming out of the bubble wrap!
You'll know when you have a clutch problem when it starts slipping
like mine did after 37,000 miles. It's not a catastrophic thing. It
just starts slipping a little when you pin the throttle and gets
progressively worse over time.
I've heard of glazed clutch plates. But that's usually something I
associate with dry clutches.
