Re: 96 slx 780
The original motor threw a rod two years ago. I do have an extra set of carbs from another slx I could rebuild. Is there somewhere you recommend to get the kit and how do I set the pop off pressure. Also I was thinking it might be the timming???? And I did drain the tank when I put the new motor in. Thank you for you responses.

You don't need to change your pop-off. www.watercraftmagic.com sells a tester - you do want one so you can always verify your needle & seats aren't leaking.

Re: 96 slx 780
I bought a 95 slx 780 with the engine already apart. Bought a Sbt motor,new reeds, rebuilt carbs(polaris dealer checked popoff), and got new fuel pump. Same problem as you 5700 rpm. If I got it on choppy water it would rev to 6200. It was like I had to get the pump out of the water, so i thought maybe it could could be wrong pitch impellar (from previous ower). So I got a new impellar. Still 5700! I leaned the carbs and enrich the carbs still 5700. I bought a set of 96 slx780 carbs off a running ski. You guessed it STILL 5700. Every thing in this ski was new. Exspensive items like the cdi I a dealer swap out from a running ski they had to see if it would help. I check the resistance on the stator. Finally I sold the ski and lost alot time and money. I have found several other people with 780 in these forums with same kind of problem ,but no real answer. Everybody told me the problem is in the carbs, I think i tried everything possible. Good luck!!!
