Probably would ship if you handled the costs and arrangements...

PRICE REDUCED !

Rochester, NY All stored in attached garage when not being used. Garage never goes below freezing. Fogged engine, drained fuel, and greased rubber parts each winter. Always used 93 octane fuel with Castor 927 high performance racing oil. ** SOLD for $2,500 ** 1993 Superjet (white) mostly stock...

Could also be an exhaust leak, choking the air intake after it builds up after riding a bit. How does it run without the hood?

Could also be a bad/clogged fuel filter. Try removing the in-line fuel filter near the fuel tank, and see if it rev’s. Less likely, but could check the pulse line to see if if has any small cracks, and is secured tightly on both ends. Good luck.

Yah. Good chance it may be the CDI. Would first check/replace plugs, plug boot connections to plug wires. Check resistance between boots, think it is supposed to be something like 3.5-4.7 kilo ohms. If out of spec, could be the coil. Can also open up the ebox and look for wet/corroded/loose...

I checked the thread on my issue and the readings were 150 and 160 psi... so not quite the same.... faulty memory.. arrrg... ( Running on 1.5 cylinders...

I seem to recall my compression being the same in each cylinder as well. Think it was apx 175 psi (girdled head). Which was misleading to say the least, given that half of 1 piston was missing. I know removing the head is a pain since you need to replace the gasket, but given all you have tried...

Have you taken the head off and checked the pistons? You say it sounded like it was running in 1 cylinder, well maybe it is. I had a similar situation and the bottom half of one of the pistons was missing. Fortunately the pieces must have all exited out the exhaust, and replacing the piston did...

I forgot I had this, and I have no use for it. The drive shaft is from a 2004 Superjet. The spline is worn (see pic), so I had replaced it years ago. The overall length is 26 inches. If you have some possible use for this, it is yours, just need to pay for the shipping cost. Located in...

I would suggest asking the folks at jetskisolutions.com. They have likely seen everything with their replacement service for plug wires/boots, coils.

Compression is way too low at 100 psi. Should be around 150. I would test again and/or use a different tester. Can’t imagine how it would run well at all at 100 psi. Plugs do look like it may be running lean, but the compression would need to be assessed first. Good luck

You could call pro-tec. My experience is that they are super helpful

Sounds like a good first step. You could try blowing smoke into the hole and see where it comes out to find other possible leaks. You can use a small straw, like what comes with some spray cans. Get some cheap cigars and blow away. When I did this once, I was glad I used flavored (cherry I...

Correct you are!

finally... a productive use for a sit down jet ski ;-)

If it is 4.3 kilo ohms that is likely ok. Could be the wires or could be a loose connection with one or both of the boots. Might want to move the wires around while checking for a spark (plug removed from head and side held with rubber handled pliers to a ground). Should probably move wires...

Would suggest some easy low cost things first... replacing plugs... check connectivity of wires and boots. Check the resistance between the 2 boots. Can’t recall what the ohms should be. You can look it up.

I had a similar issue a few years back, although not sure about your gurgling sound. Ended up having the spline on my shaft worn down to where the shaft was slipping, causing what seemed like low power. Not the first thing I would check if I was you, unless the motor seems to sound ok...

Looks like you got a couple of good replies already. Just wanted to thank you for not posting pics of your pick-axed and neglected superjet. ;-)
