I'm new to jet skis and I just bought a 1995 Kawasaki 650 TS, (couldn't pass up the deal), and I knew it needed some work. Probably been out of the water a long time. Initially, I couldn't get it to stay running and it had heavy white smoke coming out of it. I replaced the head gasket, spark plugs and added Stabil to the fuel. Now it turns over immediately, but it still smokes really bad and the idle is pretty rough. What could this be? I don't have a lot of money into it, but I would like to use the thing! Thanks!

 

If it's premix maybe too much oil in the gas

 

It ispremix, how do you check/adjust the oil injection?

 

I meant to say, it's not premix it uses oil injection. How do I check/adjust theinjection?

 

no adjustment. If it is smoking too much you may want to change oil type. Cheap oils from wally world at 2 per gallon isn't the best thing. Buy yourself some good synthetic bel ray fom a local jet ski dealer even if he has to order it. then drain the oil tank, and bleed the oil pump. Small chrome screw on the oil pump.(may have to remove cover infoot well to gain access, pump is on front of engine crankcase) Watch for the color of the oil to change, then you know most of the old oil is out. Then enjoy new lower smoking issues. Don't forget to put rag under pump when bleeding, and wipe up the mess. The oil that drains into the hull will be sucked out and put into the river,lake or ocean if not killing our wildlife when ridden not to mention it's a hefty fine.
Hope this helps,
Jody
