Does it get any better if you turn the gas selector to reserve. You might have a restricted selector valve.
Check to be sure you use the proper plugs and are gaped correctly.
Keep us posted.

Grow up. I've rebuild these skis completley to factory spec. I've replaced every single component and ensured everything is running and operating as it should and these skis are nothing but troublesome. I feel the rotary valve is more of a headache then it is worth. AND while trying to get help on seadoo forums. i have to wait days to get responses... not a really strong community here i feel. I think i know the reasoning.. Because these skis are constant problems. I went to yamaha forums and recieved 28 responses for help from people that specificially owned the same year ski. All of them said that they are very problematic. I'm going to take everyones advice however, nothing has helped yet.
You need to try advise offered, before you slam the forum!
This forum is member driven, so if your not getting a quick response it's because the members are out having fun. I re-read all of your "8" posts and it seems like you haven't really got a grasp on what is suggested to you to do. If you checked the pop off pressure like a member suggested it might have solved your problem also. Do you have a repair manual? If you want full attention to your problem than join as a premium member, and you'll get all the help you ask for...other wise you will have to wait till the regular members answer your question or a moderator gets a chance to help out. This forum is composed of 10,600 + members. There are a hand full of moderators that are non-paid volunteers like myself, that have years of experience and expertise. I personally answer 50 to 100 posts a day and answered one of your questions too, but you never responded if my advise even helped... If you don't take advise and try it, you'll never get your problem solved. Being belligerent in the forum will not help solve your problem, it will just get you ignored by the regular members.
I suggest you try some of the advice offered, ask questions if you don't understand the advise completely, or join as a premium member for more direct help to your problem.

ok ok i'll take all of your advice starting from the begenning
The ski still doesn't start right away if i turn the gas selector to reserve. I have a brand new gas selector. Brand new plugs properly gapped. As for the primer choke i've tried removing the top filter and directly spraying a little bit of fuel into the cyclinder. This did nothing I tried multiple ways to do so.
still nothing
as for .1989 SP 587 270500054 N/A BN-38 (RB) MAIN(jet)-85 PILOT-N/A 11.5psi - 12.5psi LOW(lsa)- 1-3/4 HIGH(hsa)- N/A....only difference between the yr, is the 90'sp, has 100 size jet for main
I have the factory carb on there with a fresh rebuild from seadoo. Problem i'm finding is how do test for the 11.5 -12.5 psi thing? I would assume this is pop off pressure? If someone could clarify this for me it would be greatly appreciated! as for the mainjet I have no idea. It is all factory nothing here is aftermarket. all stock 100% what is the 1-3/4high(HSA)?

In the carb if the engine is all stock if you use a razor blade to see if the tang on opposite side from the needle valve is level to the carb body should be enough. Don't worry about doing pop off for now.
Check that all the allen screws that hold on the carbs are tight and no air leaks around the gaskets. The Low Speed Adjustment,(LSA) should be at 1 1/2 turns out from seated. The High Speed Adjustment,(HSA) should be at "O" I believe on that year model. Start at that adjustment and you might need to adjust from here. Check this out and get back to us.

hey stud,..also, cut the plug wires 1/4in off from boot sides, then reattach the boots.....you said fresh rebuild from seadoo. Did they set the timing of the RV, and/or install the stator assy as well?

I put new plug wires in and they are giving great spark to the plugs Um.. Rotary valve was set to the proper degree and the stator was installed properly. Going to the shop tonight going to try everything everyone suggested. I just got my sbn Carb for 55 its a rebuilt unit so we'll see how this goes...

compression is good, as for the fuel, pull line to carb and syphon it,..dont like hold'n starter very long for it to prime...if so, keep ur choked...or you can bypass it all, use the "res" line and go straight to carb, install little clear filter also...
