Wicked stuff

I can't get enough of this stuff

More old yamaha content lol

Loving your videos. Really good info. Keep up the good work. Was surprised to hear you refer to the JetSki Bible... the Author, David Simon built my race boats back in the day. He was my mechanic on tour from 92-95. Still have one of them.

I love this lol

Great job Jimmy you are the man.

I found you because I got a 1992 wr500 from the dump and bought another 1989 wr500 hoping to make something good out of both and I just love the education you provide

I'm a new subscriber and I would love if you did something like this with the old waverunner 500 650 platform

Jim is there a fuel pump in a 1991 yahama wave runner?

these kids have no clue what they have in that Honda ski.

I love Jet Ski Jimmy! ❤❤❤❤❤❤❤

When were checking the CDI module what wires were you putting your ohm meter onto? Unfortunately the wires were off camera. Thanks so much for sharing your knowledge.

Jim, thank you it took me a while to figure out Gary Hart. I’m 62 now got introduced to Gary from John Who owned Temple city Kawasaki at the time Gary was one of my first sponsors. He hooked me up with all the gear nose, and , side, braces. mats chin pad plus all the T-shirts and shit I could ever wear. He was a great guy and will be missed definitely I’m sure he’s helped out way more riders than me used to let us come in and use the shop to tear our boat apart. Thank you Jim thank you.

Jim, this hit me hard Gary Hart was one of my first sponsors when I was racing jet skis. He hooked me up with mats side, braces nose, brace 440 superstock and my 550 mod anytime I needed JetSki stuff. He was always there to help me out it took me a while to figure out because I’m 60+ now, but he was a great guy, he would let us come use his shop Godspeed Gary on your next adventure

You don't need a second set of hands to hold the key in the start position when you're using a jumper wire to engage the starter. Just turn the key to on/run position and use the jumper wire to engage the starter

What a cool truck! You did a great job on it too. I had a 4Runner of the same generation, and recognize every sound and rattle. 👍

Always nice having a Merlin close by. 😉

Looking good Jim.. nice to see Mrs Jim cameos too 👍😎✊

Does the check valve let air into the fuel tank, or do you use it to let excess pressure out? I have mine letting air in and noticed when it got hot sitting on trailer some fuel leaked into the engine compartment.

Good job Jimmy! 💯👍

That's awesome love those old Yota's.

Good job Jimmy 👍🏻

love you

It's a Toyota it sounds like a Toyota . At least it's a running working truck again. Good deal Jim.

Nice work Jim.

First

Going to look at one tomorrow this was the perfect video thanks

sir, excellant info. BUT can u hold the carbs still so we can see the differences. constant movement, makes it hard for the old guy to focus.. thanks very much for yor time.

I've never seen a standup tow anything, that's crazy! I guess those new big 4 strokes are good for something!!

How much would you charge to do this for a subscriber?

Hey Jim! I have a 750 sxi with twin keihan carbs, I've just rebuilt the carbs are now it's backfiring out the exhaust on deceleration. I've adjusted the low screw from 7/8 to 1 1/4 and doesn't seem to make a difference. Have you got any ideas? Thank You 😁

Almost the exact same thing happened to a 650 motor I just got

you are the most expert jet ski tech I know. Can I contact you about my Yamaha xl 1200 ?

Isn’t that a 2024? Awfully young ski to have a busted fuel pump already.

Can a person remove the starter on a 1993 650SX without removing the muffler system to get to the bolts and have a passage way to get the starter out of the engine compartment? Is there a trick to do this?

I love watching your videos. I’m almost 40 just getting into standups, but you give me hope that I’m not too old. Keep up the good work

What's the " grenade " for?

Amazing video. Helped so much with 87 650 build.

You must buy an sx if your going to buy a 550 they were made from 1991 to 1995 if you see a 1990 sx it has the updated driveshaft and pump but still has the old piston port engine id avoid those unless your doing a engine swap or something like that

Great video !

Great video !

Great Video ! i'm an old Jet ski Mechanic from the 80's. Built a Bunch of 440's in my day. We used to punch them out to the Biggest 483. i Worked for Dana point Jet ski in California for many Years. started in about 1978. Worked on thousands of jet skis over the years. 440's & 550's. the old Black carbs - were Mikuni carbs. Factory carbs. very reliable. easy to rebuild. diaphragms inside. i Never dipped them in a carb cleaner that i can recall. they were about 32 mm. if i recall. We used to replace them with a Bigger Carb. from an articat snow mobile. carb. a Walbro 42-44 mm carb. it was a Nice Bump in Horsepower. We Built some of the Fastest Jet ski s of that era. 48 Mph. was the Fastest We built 483's to Run. stock compression on a 440 back then was about 135 psi. if memory serves. We used to Mill the Heads a lot. We used to get them up to about 165-180 if Mem. serves. Wiseco pistons. advanced the Timing. Ported intakes & exhaust. Dana Point Jet Ski Ruled back in the 80's. Ken Klus - Was the Owner Back then. i was Wrote up in the newspaper back then. i used to Run the Service Shop For him Back then. Those were some Great times ! Take care !

In those situations I drill a hole in the threaded shaft for a cotter pin and switch to a castle nut. I keep a supply of UHMD stock in my shop (otherwise know in some circles as SawSlick since its used on saw fences and sliding tables) and make up new flat washers, bushings etc from that material since its basically self lubricating. Works pretty good on kick-up sailboat rudders too. Have also used UHMD to machine parts for airtools that have become unobtanium. Best!

Bought a used kawasaki 650 engine was told that had been rebuilt installed in jet ski one time you start it it runs the right direction some time when you start it runs backwards check timing on flywheel it is on the mark any ideals whats wrong?

where do you get your spark plug boots that are non resistor, I am have trouble finding ones that aren’t aftermarket or oem and I know those have built in resistors.

Most educational exhaust video I’ve found

I have an 07 800 SXR that would likely benefit from this. I have had since new and the steering is a bit rough Is it a similar process to the 650? Love yer channel Jim thanks for the vids

16:52 Cotter Pin.. that reminds me, unfinished business.. thanks! 👍😎✊

Good information of a fix/upgrade.
