Here you go @Big Kahuna Whoever has ears to hear, let them hear.

Put the Yamaha 650 in my wife's ski. It starts right up and spins the prop just fine on the stand. Took her ski to the river and it would not spin the prop in the river. I assume midshaft bearing?

Jr. is quite a ways away from the Sacramento Delta. Otherwise I would use him if he has time available. I just checked with 2-stroke guru Meticulous Metal (Kelly), and plan to meet with him with the crankshaft and the wrist pins and pistons off this Wednesday !!! For the Harry Eyeball...

I will do what you guys say. But here's some more local info. This guy has apparently been doing jet ski engines for 30 years or so and is highly highly respected in the area. I will call him, but I have been warned by others who say that he is just slammed with business this time of year...

Nice bird's mouth cuts!

Hmmm . . . I just watched this video: If I hone it with a Flex Hone like in the video can I use 81mm rings again?

I will replace crank seals. What honing tool would you recommend? Replace with oem 81mm rings? If compression was good at 160 psi per cylinder would you still hone and replace rings?

See movie of piston wrist pin slop (very hard to see but I can feel it) here: https://rumble.com/v5fpmvh-1994-yamaha-super-jet-701-61x-video-3.html Question: Can I just order 1. Two Piston Bearings; 2. Two Piston Pins; 3. Four Piston Pin Clips And be good? Or are the above parts sold...

Well not entirely nowhwere. I am almost through installing my known good Yamaha 650 in the ski. And the other engine is out and on the table for disassembly . . . Updfate: 650 is in and running. So, now we have three functioning skis. My wife and I will ski tomorrow, but probably with the...

@Captnem There should be an envelope on the upper right - just to the right of your user name - click it "Start a new conversation" with @SteveC BTW, how you purchase from @JetManiac is by requesting what you want to buy from him via a "conversation." Other great ventors like @waxhead has a...

@Captnem 2 cents from the smallest least knowledgeable peanut in the gallery here. You understand 2-strokes. You understand Yamaha 2-strokes. Personally, I prefer to stay with one platform. I am not a professional jet ski mechanic or a really knowledgeable amateur jet ski diy mechanic. So I...

You can't talk about a market without talking about what you call "politics" which is what I call government interference with the market. Please come here and give me your advice: https://www.x-h2o.com/threads/engine-symptoms.210205/#post-2153423 Also, lose some weight . . .

@SteveC Photos?

I took of the coupler cover, took the spark plugs out and spun the coupler/engine back and forth by hand: 1. It felt good, no resistance and the midshaft bearing felt good. 2. The engine itself felt like the piston wrist pins were loose. Is it supposed to makes this noise while rocking the...

No, in this case Trump is the Anti-War President. Vote with Dick Cheney and George Bush who have endorsed Kamala Harris for President to continue the war in Ukraine if you want more death and destruction and support for the military industrial complex. @mikidymac No, Biden closed Anwar from...

If we can get Trump in and he fulfills his promise to “Drill Baby Drill!,” then gasoline supply will increase. And if all you guys go electric, then gasoline demand will correspondingly go down. As a result gasoline price per gallon could conceivably decrease to $1.50 or less for all us guys...

Well Jet Dynamics' casting could be better. Unless you have one of these or are pretty steady handed with a flap disk on an angle grinder, you likely will not be able to fit the Jet Dynamics rideplate for the FX-1:

And a great movie: And this is the proper use of AI:

I have the Pro Tec ride plate which is flat and spins out when entering a turn unless I am on it using proper technique. So, I ordered the Jet Dynamics ride plate today. Speaking of proper technique. I am still a very lame rider. But a couple of weeks ago, I learned that riding surf stance...

Thank you! Where did you find the DG Quadra-Fin? And what does DG stand for?
