I recently acquired a 1991 Kawasaki 550SX Standup in a trade. By viewing these images, can anyone tell me what aftermarket engine modifications it may have?

What would be the approx value of this JetSki? It runs well and has average wear and tear.

Looks like half a kerker pipe, and a head. I'm up by Sacramento CA, and it would fetch a grand or so, maybe a little more. It's hard to tell not seeing it in person
