2001 Seadoo Sportster LE. Just got it!

[Sportster-2001-951C-Stock]

During breaking in the cylinder head and body are all cold. The exhaust pipe is hot. The water coming out of back is hot.
Cylinder heats up after shut off the engine.

This sounds normal, just like mine.

I have no reference. But sounds like rich missing. Not backfire pop. :-D

A slight 4 stroking noise is more of a *burble* sound than the *pop* of a lean setting.

Checked again. The upper part of the cylinder is cold. The bottom part is hot about 65C.

It is definitely "burble". LOL

This tells me you did a good job cleaning the bypass low speed ports and didn't incorrectly set the pop-off.

Idle mixture has a large effect on hot restart after 10minutes shutoff heat soaking, the restart should be instant.

In water is the best place to set the idle speed. Over 1500 in water will be too much once it's on the trailer. I would try to set it between 1400~1500 in water.

Opened the spark plugs. It became dry now. The isolator became dark brown and not smooth anymore.

I never touched the bottom, so I dunno.

It it a new plug? I expected yellow first, before brown.

Sorry. Thought about that. It is the old one I have been using.

Opened one rave. The chocolate milk is gone. Now all black oil.

Now I'm anxious to hear about compression, if 130psi then I will consider rebuilding my 951 this winter.

Check both to make sure one side isn't wet.

Both black oily.

Wet you mean water?
No sign of water to me.

 

[Waterluvr]

Both black oily.

Sweet! You nailed it, check those one more time when your done with the ride (head bolts). I'd say this is going famously for you at this point.

Getting 1 foot of wave on the lake now. Should go home and do more break in in the morning? Do I have to finish it today. Police just came asking if I am ok. LOL. People all wondering why you got a nice toy but not playing :-D

 

[Bonmotwang]

Getting all wet now. Driving at 3000RPM in 1 foot wave.

A slight 4 stroking noise is more of a *burble* sound than the *pop* of a lean setting.

When mine was too lean it didn't pop or burble, it just would fall on it's face from off idle up to over 60~70% throttle position. Even when the carbs were clean and confirmed no leaks in the fuel system.

Now I hear the 4-stroking burble between 2000~3000RPM and it clears out with more throttle.

That's the sweet sound of enough fuel keeping seizures out of the mix. I sent most of them out that way, so long as they made WOT and weren't fouling plugs.

You got that right, nothing ruins a 2-stroke faster than running lean, besides lack of oil that is.

Keep it in the bay, don't venture out of the harbor with the container ships till it's tested and broken in!

My friends. I am at shore now. Heading home. Totally break in was about 2 hours. Cruising between 2000 and 3500RPM. About 8 times on the plane between 4500 and 5500RPM. Hit 6000RPM for a couple of seconds a few times.

Tomorrow morning will be on the lake again.
Checklist for tonight and tomorrow morning to do list.

Again. Thank you thank you and thank you your fellows. It's been a blessing, not the result, but the journey.

 

[Waterluvr]

Atta boy! Very well done, I think you earned a Molson eh? :cheers:

Nice work man, I'm glad it went well for you!
