1.5 turns out is a good place to start, then you will tune the engine from there.

Repair manual


Hi Robert:
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.

I have a 1995 kawasaki ts jet ski it runs but goes really slow will not hit high end. i just got this jet ski it looks like the carb and lower end of motor is new. i did find some water in carb and cleand...


If the carburetor was properly cleaned including the teeter-totter float needle then you may just have accidentally changed the setting screws. Try setting the the high end and low end adjustment screws the standard settings are: Low speed screw: 3/4 turns out (+ or - 1/4 turn for fine tuning) high speed screw: 1 1/4 turns out (+ or - 1/4 turn for fine tuning) If the previous owner rebuilt the whole machine but could not figure out why the boat would not rev out, the next thing to do is remove the water box and and split the halves. http://www.bikebandit.com/houseofmotorcycles/1995-kawasaki-750-ss-jh750a4/o/m3253#sch27834 If a mouse nest has been built in the exhaust system the extra back pressure could be the problem. If the exhaust coupler has broken rubber tubes, has come apart, or has not been put together correctly that might also be the cause of the problem. http://www.bikebandit.com/houseofmotorcycles/1995-kawasaki-750-ss-jh750a4/o/m3253#sch29444

Sitting for while pulled carbys apart washed cleaned reset mix screws 2 half turns, up size exhaust with reverse condes on now, back firing on deconpression.


sounds like your running lean. start with your main jet/needle adj. make sure the bike is pulling hard the WHOLE way to red. after you have that you can work the pilot jet and air fuel screw. Now do you have your air fuel screws 2 half turns out from dead bottom make it one full turn, or 2 full turns and one half from dead bottom. if you have not installed a jet kit there is where you need to start. and please dont forget to sync your carbs when your done.
If you can give me the jet sizes, needle settings and air/fuel screw setting. and we will get this worked out
