slx low rpm's
I am sure that this has been covered soemwhere but I can't find it.
I have a friend that has on 96 slx that will only rev up to whta sounds like about 5000 or so. The MFD does not work so we don't know exactly. It revs up and if you pull the throttle all the way you can hear the carbs suckin but it does not go any higher. We have jumped to fuel sensor to bypass that so that was eliminated. It was running well earlier this summer and next time out it started this. On the water is barely gets up on a plane. Any ideas guys?

Sounds like it is in limp mode. Disconnect the gray wire coming from the CDI(this will disable the rev limiter) and see if it runs better.
This is for troubleshooting only, dont leave the gray diconnected.
Lets us know what you find.

Just to be sure. I need to open the cdi box and do that correct?
Thanks for the help already.

You might want to make sure the oil is full and nothing is blocking the water passage as well.
When you say you by-passed the fuel gauge, how did you do it?
You would need to disconnect the fuel sender and then put a resistor inbetween the two wires from the sender unit to the electrical box in order to fool the system.
We're still looking for a crating company in FL to get the SD packed up so you can send her here to Cali.

Hi Al thanks for the help. Let me know when you are ready on that ski. I will be gone for a couple of days to Vegas next week if I don't call you back thats why. I jumpered the wires at the tank with a resistor. I used to have one just like this and that is what I did and it worked until I could fix the float. It could have something in a water line but it runs the same in or out of water. You can hear it rev up then just quits reving. Havent pulled the gray wire yet will try that shortly.
