[@jamesdaugherty-e8c]

very informative and understandable

[@Aroyslife]

Man I know these are old videos but damn I seriously can not thank you enough for these videos. I am rebuilding a 650sx barn find I found out here in Austin TX. And there’s have helped so much! Trying to follow all the videos so I can get this baby running in the 40s!

[@jetskijim007]

That's so awesome! post back here in the comments your speeds when you are done! :-) It will inspire others...

[@Debbielahey-ds2gu]

Great info!!

[@CB-425]

Great pacing with all the info!!

[@jetskijim007]

Thank you for the feedback. :-)

[@photonman48]

This video was incredibly helpful thanks for posting

[@carson2276]

Please work on my ski, you're the best I've seen!

[@AtimatikArmy]

Great video! You should do a deep dive into the whole crank timing/rebuilding! I was super interested in that as I know these cranks are rebuildable, just not easy!

[@jetskijim007]

Thank you for the feedback. :-)

[@mjbjw77]

Great job and always informative.!

[@lowleebird1493]

Great job Can't wait to ride this bad boy.

fiberglass reeds are interesting...

[@batteryman16]

Some great tips, thanks for sharing!

[@jetskijim007]

Thanks for watching!

[@roostingthe6520]

Awesome video! Id watch a full video on timing a crank and truing it. Ive always been curious. I've built over 1,000 engines, have a full machine shop but always send those out.

[@dgc940]

You remember the old boyseen reeds wanted you to remove the stock stops. wonder if they did that to stress and sell more reeds? Are you using the bottle of Lucas for assembly lube for bearings?

[@jetskijim007]

Yes! Very good eye, I love Lucas oil!!! I do remember boyseen doing that, but in reality, when I bend my stops, they rub the intake, so removing them would definitely give you a little bit more, but i like you are saying, I like giving them a profile to ride against so they last longer. :-)

[@loganrussell9641]

Waiting for this channel to blow up

[@dreamlinerkoa6438]

Interesting 😮🎉🎉

[@markusrice9610]

I always just JB weld crank case drain holes shut. Have never had an issue and it's cheap.

[@fomomofo6917]

Not as cheap as a bolt from the spare bolt bin.

[@JetSkiBuyFixPlaySellChannel]

You can also fill the engine with water if you run it on your garden hose and turn the water on first. Engine needs to be on before the water. Also need to shut the water off and then stop the engine. Towing a ski not running faster than 5 mph can back flow the exhaust and fill the engine with water. If you ever suspect the engine has water and you have removed the factory drain you can pull the plugs and crank it over. Anytime you get water inside the engine you want to get it running again so you dry it out. Water in the engine rusts the crank bearings and your engine won't last long with rusty / pitted bearings.

[@JetSkiBuyFixPlaySellChannel]

If the ski has a lanyard, hit the start button with the lanyard off so it will crank over but not have spark. Which can damage the cdi. Otherwise ground the plugs by touching them to metal any time you crank it with the plugs out.

[@dougfeehan8421]

Excellent Video

[@deadengine]

I get it...

[@gittingjiggingwidit]

all that water in the engine! ugh

[@WildChinoise]

Super interesting!

[@spacenut708]

did you do any chamfering?

[@jetskijim007]

LoL, not on this one, but we will do some porting in the future...

[@DonziGT230]

2:35 Running a motor with a beat up head doesn't show how resilient it is. I've seen much worse that ran with no noticeable effects, but I would knock down any sharp points to reduce the chance of a hot spot leading to detonation.

[@JetSkiBuyFixPlaySellChannel]

Most people think the head is toast if it has some damage. Like you said it rarely makes much difference but it's a good idea to knock down the points.

[@arjanvogel6444]

Thanks for your vid 😇💟💟💟 Love and bless you Jim. Nice little motor thanks for showing us all.

[@lchebuhar9212]

Tell us about the vehicles on the lifts? Future projects? 💪👍🏼

[@jetskijim007]

Absolutely! Current actually, To be posted in the future for sure! The Toyota Is Jettrim Founder Gary Hart's original Toyota 4x4, currently owned by Bullett Racing. I was fortunate enough to be tasked with the honor of rebuilding the engine, and bringing it back to roadworthy condition. The Cobra running gear is going into a fox body (future project for sure)....

[@AtimatikArmy]

@@jetskijim007 In 1993 Gary Hart custom made me and gave me a Go-Ped deck mat while I watched on one of the nights during the World Finals when everyone came down to his shop and watched us rip our modded Go-Peds around his parking lot. Go-Peds were still a pretty new thing to this crowd at the times and I don't think anyone had ever seen them modified to the extent we had them there (liquid cooled, nitrous, etc, expansion chambers, strokers, etc). It was an exciting time for us as well as for the JetSki industry as a whole back in those days. We were there representing the Go-Ped factory and they were becoming quite popular with the Jet Ski crowd. Many, many good memories from those days. I also raced JetSkis as that was my other main hobby and won Novice 550 Limited class that year as well! Chris Fischetti allowed us to come to his house and his father "pops" even leant a hand to help me get ready. Magical, all around....

[@roostingthe6520]

Its funny i put a 55 pilot in most of my dirt bikes and it makes a huge difference.

[@fynvention3689]

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

[@chuckcafiero4546]

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

[@martykath4427]

I once drowned my Ossa 250 motorcycle while competing in an enduro race in the 70s. After draining the carby bowl and the ignition cover I removed the plug with the bike upside down and pumped the kick start. What amazed me was how much effort it took to get the last of the water out of the thing. Drops of water kept shorting the plug. took 20 minutes to get going. Luckily I haven't managed to drown my SRX 800 yet.

[@lucasorf6434]

Do you reccomend running reed stuffers in modified 650s?

[@jetskijim007]

no, but I recommend them for any other ski. The 650 has the smallest reeds ever used, they don't need to be made any smaller. Thank you for watching. :-)

[@juanpabloramirez6565]

Very nice explain, if you make an cranckshaft rebuil video want to see it complete from 0 ton100%, here not found who make this. Please let me know

[@martincogdell9188]

Hi can you get an msd ignition pack for a 1989 650 sx 😊

[@michaellauer3397]

Jimmy… What about the main jet… there is less gas in our gas with e10…

[@jetskijim007]

Well, yes, but, when you put a bigger pilot jet in, it richens up from idle all the way through full throttle...

[@michaellauer3397]

I can see that… I was building boats with Rockfish boats. The first two were two strokes. I really liked them, but customers want 300hp over light weight. I was an RD350 guy a hundred years ago, and when I raced motocross in the 70s Kawasaki came through and invited some of us to go check out the then brand new JetSki. The very first ones were a little doggy, making them a little harder to get up on 550 came out… Wow. Digging your channel

[@journey_w_John]

This might be a stupid question but I’m assuming stainless 8mm for the case drain holes?

[@jetskijim007]

I would recommend stainless yes. :-)

[@Trumponepingonly]

Where you located

[@RaymondCoggins-xd2re]

Oh yeah it was in salt water

[@RaymondCoggins-xd2re]

I've got a2014 Sea Doo GTI that was sunk oil looks like McDonald's shake pumping oil out took forever we put desil fuel to clean cranked over for a minute then pump oil out again put oil in and cranked it over again still find water in oil what can I do to get all water out any help would be appreciated

[@jetskijim007]

Unfortunately the only way to get it cleaned out is to change oil 5-7 times (expensive i know) and eventually all the water will come out.

[@RaymondCoggins-xd2re]

@@jetskijim007 thank you very much

[@RaymondCoggins-xd2re]

@@jetskijim007 do we crank over engine each oil change?
