Hey guy and gals I just bought a 1989 kawasaki 650 sx. This is the first stand up ski I have owned. It has been sitting for over a year. It will start with the help of starting fluid but wont stay running long. This ski has a few different mods like a primer, westcoast pipe, flame arrestor, aftermarket aluminum water box, and maybe a aftermarket carb not to sure I am still learning. My question is since it has been sitting what do I need to do to make it run good. the guy did say it would smoke his 92 750 so I am excitied to see how good she can really run. Your advice would be much apperciated.
