For sale 1990 GS500E engine parts

[Woodchopper1979]

I have various parts from a 1990 era GS500E motor.  It'seems black.  Starter, upper and lower crankcase halves, both side covers for crankcase, flywheel and stator, 1 good connecting rod, transmission, head, cylinders, cams, timing chain, cam followers, etc.  Let me know what you need. I'm in the Lehigh Valley Pennsylvania area, I could possibly ship the items.

Are the cylinders still available, serviceable, and how much?

Are you willing to sell valve shims? Which sizes?
Thanks
