1998 Seadoo GTX Ltd Carb rebuild

[Edwinh1234]

Hello, I recently bought a 1998 seadoo gtx limited and the past owner apparently sent the carbs off to be rebuilt and I just wanted to make sure it looked correct before putting it on the ski. Are these correct? The black line is way too big and loose currently. Theres 2 open spots for lines to be connected to as well. I circled them and labeled them #1 and #2. What goes to these spots? Thanks in advance.

Couple things.
1. Never trust someone that "rebuilt" the carbs. Verify for yourself and make damn sure everything is genuine Mikuni.
2. You better see if your accelerator pump inlet line is supposed to have a restrictor orifice.
3. Use the correct hose.
4. Hose #2 is the fuel inlet form the fuel selector valve.
5. Can't see it well but I think #1 is the pulse line from the cases.

When I open the carbs, how do I verify that it’s genuine mikuni? Also, what exactly is the accelerator line and what would the restricter orifice look like? I’ll do some research to see if I can figure it out myself as well.

Of the button on the diaphragm on the metering side of the carburetor is anything but red it’s not genuine Mikuni. A pop off test will tell you if it’s the proper spring in the carb.

The needle seat has a little square within a square on the bottom next to the size if it is genuine mikuni.
The yellow line that goes from the body of the carb to the pump is the one I am talking about.
1998 GTX limited should have a brass restrictor jet in that line, it is number #72 on the parts diagram. Without it you will have hesitation.

Just checked and there’s no restrictor jet… I’ve searched everywhere to buy one but can’t find it. Any idea where I can buy one?

You know anything about using a pilot jet as the restrictor?

I would be surprised if Riva had it as it is discontinued but a phone call or email would verify.
