@khanservativ2401 aftermarket electrical parts are well know to be junk. Your best bet is used oem ones. You can useva 4 wire one. The 5 wire ones have an extra ground. Or so I've heard. It's a good idea to add a ground wire from the ebox to the engine.

@@JetSkiBuyFixPlaySellChanneldiscovered it was only that 5th ground wire that fried. The one that fastens to the back of the stator. The rest were ok. So that 5th wire on the stator harness is an additional ground?

@khanservativ2401 sorry. That's about the extent of my knowledge on the stator wires. You might be able to verify it's a ground wire with a voltmeter set to ohms. Might also try adding a ground wire from the ebox to the engine to see if it works again. I'm still trying to master the electrical side of these skis.

@@JetSkiBuyFixPlaySellChannel Ok - Thank you very much for your time. I'll do some more study. The ebox ground your suggesting, are you saying that would be a 6th wire? An additional ground from the box itself to a bolt somewhere on the block? Sorry. I really do thank you for your advice.

@khanservativ2401 some skis like the js440, js550, 550sx came from the factory with a wire from the ebox a stud on the intake manifold. Since your ground wire burned up I figure it's a good idea to add one. It's not going to hurt on any ski to have a ground wire from the ebox to the engine. Extra protection for the stator I figure.

@johnbrown2030 my guess is the fuel pump diaphragm.

You could try adding a primer.

@iammikeyl tricities just open a lane last week. I watched another video on CZcams showing how to get an appointment. The trick is you have to be in the website and refresh it right as it turns to 11 am on Tuesday mornings. The slots fill up in about 20 or 30 seconds. You want lane one or lane three. Lane two is for dealers so don't waste time trying that one.

@@JetSkiBuyFixPlaySellChannel Thank You So Much For Replying. Gave it a try this morning (tues)and in a blink of an eye, before I knew what was happening all appointments were filled. I called the Tri-Cities number and it is "Active but not in Service" ??? Searched the topic on Reddit and people statewide are fed up with this system.

@iammikeyl they won't return calls or emails if it's anything to do with making the appointment. I tried before. I've been able to get 5 appointments at the Yakima one. I learned how by watching another CZcams video. It's ridiculous how fast they fill up and that they don't have a better system.

@Bumsik777 Kawasaki doesn't use any one way check valves. A lot of people remove the oil injection system and premix their gas.

@Bumsik777 I've had two skis where the oil pump gets a spot where it doesn't hold pressure so oil in the tank drains into the engine.

@@Bumsik777 you should join a Facebook group for your ski. You can get answers a lot quicker.

@danielokuda you don't have to use the template sensor. Both plugs fire at the same time every time so either way will work.

1989 was the first year Kawasaki made a 650 ski it was the X2. In 1989 they came out with the 650 SX. In 1992 the came out with a 750 SS, which was a sitdown Jet Ski. If you check out Partzilla dot com you can find which models they made each year. In 1982 they made a JS440 and a JS550.

That is your temp sensor. It bolts to a bracket that hangs down in the front left corner of the engine bay. Attaches with a 10mm bolt. You can see exploded parts diagrams on Partzilla dot com. Shows every single part on your ski. You could also join the Kawasaki 750 sitdown group on Facebook and get quicker answers there. I started that group.

Check out my newest video where I lay out all the parts of the cooling system and explain how they work. To answer your question. The main part that provides cooling is the brass 90 degree fitting on the side of the jet pump, it hooks to a hose that goes through the hull and into the bottom of the exhaust manifold. Make sure that is clear and not clogged.

I asked them about the chain being welded on. They said that's not allowed. Has to be bolted on each side and seperate from the bolts that hold the hitch

Oddly they don't seem to mention any specs on the bolt size or the chain size. And really every link on a chain is welded. But I'm just looking to show what worked for me to get it to pass the inspection.

@@JetSkiBuyFixPlaySellChannel I'm just thinking out loud. I appreciate the video.

Lol. Thanks. I've learned a ton from CZcams videos and the internet. I try to post answers to commonly asked questions that come up in the Facebook groups.

For a 900 start with the low 1 and a 1/4 out. High 3/4 out.

What would you like to know? You can slide it right out when the motor is out.

The two big red wires? One goes down to the starter the other goes to the battery positive post.

It won't ruin it. I only do it occasionally to test it sometimes.

The start circuit should be open until you press the start button. The stop circuit is open if it has a lanyard and is in place. If ot doesn't have the lanyard style it's an open circuit until you press the stop button.

If you look at my shorts videos there's one on doing a continuity test on the stop button.

What ski are you working on? I can get the starter out on most Kawis with the engine still in. On some the exhaust needs to come out.

Either JB Weld or 5 minute two parts epoxy.

Not sure. Never messed with a ZXI or triple cylinder ski. I'm there are a few similarities. The coil would likely be different.

On the three light bar at the center rear, is that just a running light or wired into your brake light?

@jenslee1678 the only lights that change when you hit the brakes are the two at the back corners. During the inspection they don't seem to actually check that they function. At least that's my experience with the last three trailers inspected in Yakima. So the three in the rear middle are marker / running lights.

Thank you for the help with this, I appreciate it.

@jenslee1678 also the three lights in the middle are only required on trailers widder than 80 inches.

They go to the cdi box to kill the spark. Not used in this video to simplify it.

@@JetSkiBuyFixPlaySellChannel Do you have a black and orange wire that comes out of the junction box at the top? If so where do those connect? I have a orange and white connecting to the relay but then have a black and orange still.

@@gavinvezendy7493 which ski are you working on?

@@JetSkiBuyFixPlaySellChannel1989 Kawasaki x2

@@gavinvezendy7493 you might check out the Kawasaki X2 group on Facebook. You can get answers a lot quicker.

Let me know if you have any questions. Or join the Kawasaki 750 sitdown group on Facebook.

That must have been quite the bike.

@@JetSkiBuyFixPlaySellChannel Kawasaki H1 500 with about 60hp on tap and weight only 384 pounds so performance was good for its day.

Check your selector valve, hoses and pickup in the tank. Fuel level also needs to be high enough for the on tube. You might have a cracked pickup tube sucking air.

@@JetSkiBuyFixPlaySellChannel it was perfectly fine before I don’t know why it’s like that now. Worst case scenario it’ll just run off reserve right

@@JetSkiBuyFixPlaySellChannel my hoses are in correct spots

@@Xprototype12x you can run it on the return no problem. To test the ON line unhook the reserve hose from the carb and unhook the ON hose. Set the selector to on. Blow into the return line and fuel should come out the hose to the carb.

Did you get a throttle wheel too? I think my bracket is on the motor mount. I sold the ski so I can't check. You might join the 650SX group on Facebook and do a search for the bracket or just ask there.

@@JetSkiBuyFixPlaySellChannel yeah everything’s good expect for it not picking up fuel when it’s switched to ON but it doesn’t really matter anyways because u could just delete the whole switch and go straight from the tank to carb so I think it’s probably fine ?

Thanks.

No. Only the Keihin 28mm carb has a seperate fuel pump. The Mikuni has the pump built into the carb. Check out my video What carb is in my Jet Ski.

I don't know how to translate a video. I recommend joining the Kawasaki 750 sitdown Jet Ski group so you can post questions there and Facebook will translate it. I'm an admin there and created the group.

Thanks! It's the nicest 440 /550 I've owned and the only 550SX. Mechanically it's in really good shape. Needs a little work cosmetically. I'm planning to do the reproduction graphics from PWC Graphics and maybe do Jet Trim mats. We did a huge roadtrip to go get it. It was a bit of a gamble. We bought it and a 750ST that sat for at least three years. The guy didn't know a lot about skis. He was able to verify the engines weren't siezed. This one sounds good after a carb rebuild.

@@JetSkiBuyFixPlaySellChannel I am searching for a 94/95 550sx here in Michigan. They are sweet

That's the original Kawasaki ebox mount. Part number is 32099-3750. Looks like Partzilla might have then but they're $127.

I would open up the start switch and clean the contacts. Be careful there are some small parts inside. I'm assuming it's a fully charged healthy battery.

I'd recommend checking out some of the Kawasaki groups on Facebook. A lot of them have over 5,000 members so you can get an answer a lot quicker.

Kinda sounds like a 650 stator. It's possible to put a 650 stator and flywheel on a 750. You might look at my other videos to see some differences. Or join a Kawasaki Facebook group and post a question there.

People are usually trying to go the other way and put a 650 stator and flywheel on a 750. Let's you advance the timing and gives you a lighter flywheel. Seems like you should be able to but I'm not 100% sure.

The engine was ported by Group K. What parts are you looking for? You could do a high compression head. The ignition system on this is stock and the carbs are dual Mikuni ibody 40 mm.

I am a new guy to 2 stroke tuning, i might be looking for another exhaust and a a cylinder head to increase compression. I am from Germany.

@peterheunz9391 I recommend checking out some of the Kawasaki two stroke Jet Ski groups on Facebook. There are people all over the world in the groups. You can find parts and help doing upgrades. I think Jack Hollmand is in Holland and does lots of stuff with the X2s.

Thanks a lot i will check that out! They are kind of rare in europe

Thank you. I wish I had more time to shoot videos and actually edit them. There are two Super Chicken groups on Facebook. One is a buy and sell group. It's pretty hard to find a good deal in a group of enthusiasts. I recommend putting a wanted ad on Craigslist in the boats for sale section. If you're looking to get started in PWCs, I recommend the 90s Kawasaki 650 and 750 skis. I can usually find good deals on project skis if I look long enough and I think Kawasaki's are the easiest to work. Also plenty of parts available. Seadoos are my least favorite to work on.

Thanks.

Where are you located? There is a buy / sell Super Chicken group on Facebook. Best way to find one is to put a wanted ad on Craigslist in the boats for sale section or put an ad on Facebook.

@@JetSkiBuyFixPlaySellChannel Thank You

@@MisterDoug1649 no worries. I'm in Washington state USA. There are two Kawasaki Super Chicken groups on Facebook with over 5,000 members in each one.

Oh my god I have looked every where for this I got a gokart with the 750 motor and it didn’t have any of the boxes and there was no wires for me to plug a coil into thank you so much

​@LifeAtTheCove do you have videos of the go kart?

By reducing the ohms (resistance), the car is able to move the fuel needle from empty (bottom float controls that portion of the tank) to full (the top float). When ohms are reduced, voltage increases, allowing the needle to move more or less since it uses different voltages on an electromagnet to display fuel level.

The Kawasaki 750 SS / sitdown skis have a primitive fuel gauge. For each float that drops one light goes out on the "dash". 4 lights is a full tank, 3 is 3/4s 2 is half and so on. There is also a light that comes on if the oil level is low in the oil tank and a light that comes on if the water temp sensor detects it's too hot.
