Oil Leak / Cylinder gasket replacement?!?

[JarredD]

Just got my 2006 GZ250 with 5500 miles on it and Im noticing a small leak on the left side where the cylinder gasket meets the base of the motor. It was all clean before when i bought it (last weekend) so I had no clue about the leak. It seems to be really small and slow, but I am concerned about any leaks. I was wiping down the motor and inspecting everything closely and noticed a small piece of black paper gasket sticking out on the left side between the head studs. I pulled it to break off the small piece hanging and the whole section between the studs slid out. Nothing spilled or anything like that. Just a piece of the paper gasket feel right out...

My questions:
Is this normal for this mileage?

Does anyone know if the motor needs to be removed to replace the cylinder gasket? (not the head gasket, but the part where the cylinder meets the base of the motor)

Any ideas on cost from a shop doing the work?

Anyone else have this issue?

I havent been able to further inspect the leak since this happened yesterday in teh evening...

Any help is appreciated...

Thanks,
Jarred

P.S. I'll post pictures of what I am referring too as soon as i can take a look at it today... The bike is my only means of transporation right now so I'd like to fix this sooner than later!
