Ok, so my twin brother got messed up in Iraq and he has been wanting a jet ski. I am going to look at one for him tomorrow so he can have it for when he finally gets home. I live in lincoln NE, and this will be the first jet ski I have ever looked at. It is a kawasaki 1100 ZXI. I was told it runs great, but I have no idea what to look for and what to ask about it. He is asking $2000 and I was going to offer $1800, comes with a trailer. What questions should I ask, what should I look for? Anything I need to do before hitting the lake the first time on it? I understand to run 50:1 oil/gas, flush it, scrub it down good, wash the motor, WD-40 lines and connections, and use fogging spray on the carb. Any help would be great.
