I have info for my F1000 brethren who might be considering a Kawi.
Avoid at all costs engine # (last 8) BA 004217.
I went out of my normal loop to purchase, so I could have a spare and this engine was NOT as advertised.
Thankfully I was eventually able to get a refund, less return shipping and some fees, but RUST in the valve seat area? For real? I was told that was normal and to just clean it up w/ some spray cleaner. Yeah riiiiiiiiiiiiiiiiiiiiiiiiight!
PS I do have complete, low mile latest gen ZX10R carkits available - NO rust in cylinder head- BONUS!! :O)
