Alright, I'm going to tear at it more this weekend. Is there any chance that a sheared woodruff key would cause this? If there is a chance, then I'd pull my engine out this weekend and get the flywheel off to check things out. There's literally only 3 more things left to check, woodruff key...

I'll check through the harness. I did recently have the ski apart to take the weights out of the front and install tubbies. But the only wiring up there is for the start stop switch, should I try a new voltage regulator? I'd hate to throw money at another part just to find out it made no...

Well I think I've ruled out any chances of it being a fuel issue, I've pressure checked the tank, switched carbs, even held it wide open while it acted like it's being limited and poured gas down the carb throat and still no difference. I'll check compression again, but I really think it's...

Well... Switched the carbs... No change. Still the same results. Any other ideas? Would weak flywheel magnets cause this? Or could it be timing related..

I'll check them again, it's just weird to me that it would act the exact same way and just get worse even after fully rebuilding them. I'll throw some on from my 650 and see if it changes anything

Nope, checked the waterbox and lines. I just don't get what it can be at this point, it ran perfect and just started getting worse. I've gone through everything I can think of except the flywheel and woodruff key (can't get the flywheel bolt off)

Compression is 150/150. Checked the reeds and all are perfect. Coil is reading 4.6 ohms across the spark plug leads. Carb is rebuilt 100% with parts from SBT. The engine runs and doesn't die and seems to run perfect at low rpms so I don't think it could be a kill switch issue. It won't rev up...

It starts each time like it normally should, no issues starting at all. It's when I give it gas it just acts like it's on a low limiter. (I disconnected my temp sensor inside the ebox too btw). It just started it one day and I could get out of it by restarting it a couple times. Then it hot...

Any ideas? I'm completely stumped by this. I literally threw my multimeter across the room

BR8ES, didn't mess with the gap, theyre at .025, also tried some equivalent champion plugs (I don't run them) and had the same results

I have an issue with a 750sx where my engine isn't revving up over 3000 rpm. I can't even get it on plane. It just feels like it's on a rev limiter. I've replaced EVERY electrical part on my ski with a brand new one except for the regulator/rectifier. Replaced CDI with a new msd enhancer...

Exhaust leak, tighten up all the clamps you can see. They used to come loose all the time on my 650

I cut out the front piece and glassed it closed, my rear tube fits fine. But I'm running a single carb and sx hood so there's nothing in the way of the rear

Yours isn't fitting?... Mine fits perfectly fine with a limited pipe. I did cut the tube in the front though to clear the pipe easier

That's what I was worried about, I haven't ever seen any stand ups as rentals, I was hoping it'd be different by the ocean, guess I'll check it out more when I get down there. Thanks guys!

Where are some good places to rent stand ups in Florida? I'm taking a trip this weekend but can't tow mine the 30 hours. I'll be around Tampa but I'll travel around wherever I need to just to get to ride in the salt :Banane01: Help a guy out!

Turn it all the way in, brings it up to 8500 if I remember correctly

Might be a stupid question, but what parts are interchangeable between kawasakis and yamahas? I'd like to know what I can interchange between my skis. I've heard the ignition coils are the same, anything else?

I bolted it up in the exact way it was so I hope it's not bad. It's a brand new stator from sbt. I'm about 90% sure, what can cause it to shear? I haven't tooken the flywheel off at all and didn't run it long backwards. Plus it runs normally when it starts in the right direction

Keys fine, didn't leave it running long that way. And I'm running an msd enhancer without a timing advance so it shouldn't have advanced that far. As far as I can make it out the stator only went on in one position so it isn't possible to get it wrong. I can get it started normally but I have to...
