Well thats up to you if you want to give him any more money, but I can completely understand wanting to actually see what he is talking about. If you do have him do that I would ask to see the carbs off the other motor he installed. I can only assume those have a single pump like yours and he maybe just hasnt realized it. Worst case scenerio, since he claims it ran fine with "his" carbs on it, see if he will guarantee this and just buy the two he has and let him install them. Providing he doesn't want an astronomical price for them. If in fact you do this see if he will take your carbs in as trade of some type or if not keep them and sell them yourself to recoop some of your greenbacks.

I really wish i new more about these things but we all gotto start somewhere i guess

Thats not a bad idea actually, will have to ask him

Lets see what he says tomorrow, just want it sorted before december so i can take it down to the coast :-)
 
Why not do the work yourself? The fuel system on these machines are super simple. IMO, if you rely on someone else to work on your machine you are just asking for problems. Do it your self so you know its done right. And no offense but what in the hell is the point of you looking at the carbs yourself if you cant even take them off yourself? Would you even know what you were looking at?
 
Three months ago I knew nothing about them either but I bought one and started wrenching on it. Yes the carbs and fuel systems are pretty simple. If you are mechanically inclined you can probably fix it yourself. First time taking them off and on you will be cussing up a storm. But after you do it once, then go buy the tools you need, its pretty simple to remove and reinstall. Plus there is a wealth on knowledge here if you search around and folks are glad to help with any questions. Thats how I learned what little I now know about them.
Either way you go good luck and keep us posted. Your experiences can help others here as well. Mine has basically the same problem you have and im still working on that myself so Im curious to see your final fix.

I would have done the crabs myself but i was worried that the i would mess up the float in the carbs, the rest seemed pretty easy

I have a basic idea what i'm looking for, plus i'll be able to take pictures and upload them here so the guys can get a better understanding as to whats been done

I read through most of the service manual and it doesn't seem to bad, i'm a bit confused about the high / low screw settings but i'm sure i can get it with practice.

I agree with you 100 %, sharing your experiences can only help others, With a forum like this you can't go wrong :-)
 
Do enough searching here and around the internet and you will find what you need. There is a tech articles forum here that will probably help you. Somewhere there is a pictoral of the actual rebuild procedure but I dont remember where I saw that right now. If you visit Mikunipower.com and read the tuning manual, you can find interesting info on exactly how the carbs work. It explains what jets flow what fuel in relation to throttle position. Very interesting if you dont already know it. Refer to the BN series carbs, specifically the super BN. Although the info is great do not set your carbs by the settings in the mukuni manual, use the ones in the seadoo manual specific to your ride.
 
If you buy those then you will have to rebuild them as well. Those carbs still have the grey tempo fuel lines on them so its almost a guarantee them are gummed up and will need a through enternal cleaning and servicing.
Try this, Get in touch with Watercraft Magic in Glendora CA. and talk with Chris. For about the same price they will rebuild your carbs and tune them for you. When you get them back in the mail all you will need to do is bolt them on and I assure you they will be spot on. Shipping might be a b**ch from South Africa but your carbs will be right.

I actually just purchased them already

My thought was this, hope it works how i want it to but since my current carbs have been rebuilt with new kits etc

So i'm just gonna take the fuel pump from the new carbs and fit them on the current carbs

PLus i think the carb kits came with the stuff to rebuild the pump as well if i'm not mistaken
 
So here is an update

The mechanic transferred the crab kits into the new carbs i bought

I took it to the lake today and was very disappointed

Firstly, the idle on the trailer starts at around 2k rpm then goes up to 3.8k-4k rpm and stays there

In the water, it idles at 2k rpm which i know is pretty high

I turned down the isle screw as much as i could but it doesn't make a difference

For the forst 30-45 minutes, the ski ran okay, did not bog down but was very limited, 5.5-6k rpm max and 45-50 mph max

Then i parked it off for about 5 minutes then jumped back on

The ski was worse, could barely hit 4k rpm and rev was very bouncy

Couldn't even do 40mph

I am at a brick wall here, my mechanic does not seem to know how to fix this

any idea's anyone

I read somewhere that it could be an air leak where it causes the ski to run lean, how does one test this ?

I'm thinking that i should just try pull the carbs myself and sit and make sure it's 100 %

Anyone know where i can find a tut on how to remove the carbs from a 2000 XP Limited ?

Does the black exhaust pipe need to be removed ?

Any help is appreciated guys, the ski is just frustrating me

Spent almost the equivalent of $1000 so far in labour and parts and i'm no closer to fixing it
 
LOL beggers cant be choosers....in this case that guy might be the only one around that knows ANYTHING about Seadoos in Africa.

With that said...How in the fawk can that guy not get it working if he used carbs off a different machine and it ran great? That makes zero sense to me.

The pipe doesnt have to come off; you can get the carbs out. Its not fun...but its better than a GSXL as far as room to work.

Be very careful with the fuel line nipples....they break VERY easily.

Lol, there are some good guys here but he was the most convenient

Just goes to show that convenience isn't everything

My thoughts exactly, when i send my ski to a mechanic, i expect him to tell me what the problem is, not guess and go

Thanks, this should be interesting this weekend lol
 
I've had one machine that I couldnt get running correctly. I prob put 15 hrs into it b/c at about hour 6 I just wanted to figure it out.

Otherwise...I had many kick my asz but I eventually got it. I never charged all my hours on those.

I ended up wrapping everything into a barter deal for a 96 GTX I had gone thru and parted his machine out.
 
I'm an IT guy so i am somewhat technical but when it comes to ski's and bikes, i'm at a lose

I guess we all have to start somewhere, if i had your know how it would have been sorted by now most likely lol

I started the ski up again this evening, was idling nicely for a change at about 3k rpm, then every 3 seconds or so it will have like a "miss"

the revs will just jump slightly but you can hear it

i reved it up a bit and seemed to rev fine

Another guy told me about a L bracket type thing that sits on the head somewhere, i thing there is a temp sensor there as well

He also mentioned checking the O ring on the fuel filter for any leaks
 
They basically give the motor a broader smoother powerband.
Have u removed the sparkplugs and checked the gaps?also remove the sparkplug cap by unscrewing it from the HT lead and cut a little wire off and rescrew the cap(suppressor?) On.and secure with a cable tie...also check that all lines are tight and no air is getting sucked in to the fuel system.also checks the pulse line from the engine to Carb,make sure it is tight and not leaking.this operates the fuel pump.and make sure all the fuel lines are connected to the right fittings.

To be honest, i haven't checked the spark plugs

The Ski was by the mechanic for a service also and the plugs where changed

I know the new plugs are NGK's, what is the gap supposed to be for a 2000 Seadoo XP ?

Stupid question but can i check for air leaks by using a syringe with some water maybe and squirting around the pipes and seals etc ?
 
Check the gaps yourself.some people think spark plugs come pre-gaped.a light little tap on the electrode is all that's needed to close the gap. Not sure on your model.my 97 gtx is 0.5. It does sound to me that u running lean.the fact it starts low idle and climbs in revs as it leans out.I think from starvation...I might be confused maybe one of the other guys can confirm this. If u had to squirt water on the fuel line connections u could potentially suck water into your fuel lines.what u need to to is pressurize the fuel system. Then squirt soapy water and look for leaks/bubbles....but first if all the fuel lines where replaced first make sure the is no loose pipes/hose clamps.and. check that the fuel filter has an o ring.it could be something else but do the basics first.do u have the shop manual? What province are u in?

I'll check if i can find the correct gapping for the plugs

If it runs lean, will the plugs be very dry ?

Thanks man, will definitely try that

Need to sit from one sit and test each and every pipe, including that O ring

My mechanic now wants to put 150 needles in the carbs to see if it helps, he said the stock was 162 or something

I do have the service manual

in JHB
 
U have ridden it before with no issues right?.sounds like your mechanic is treating the symptoms instead of the cause. If he rebuilt the carbs correctly and checked the pop off pressure.they should work without modification...
