You can see that I was happy with the bike, replacing it with a new one the same.
I have swapped the exhaust systems accross. I don't like the cheap looking cost saving glossy black bits on the new bike and the more I look at it, the more I like the Black Paint job. I still own the old bike, it is on consingment at the shop. I'm sorely tempted to swap the black tank, front and back fenders and the Matte Brown sidecovers and air box for the Slime Green and glossy black stuff. Decisions, decisions.....................
very nice 
Yeah I like Kawasakis.
