SX/SXi/SXi Pro Would a bad voltage regulator/rectifier cause my engine to not rev up?

I just read back thru all that was already posted. When you disconnected the heat sensor, did you just disconnect it or did you replace it with a jumper? Not 100% sure on the older kawi's but my 06 SXR needed a jumper to replace the under hood sensor. Simply removing it opens the circuit and effectively triggers the limp mode. There was also 2 sensors on the SXR, one in the pipe and another in the engine bay right above the ebox.

P.S. Limp mode holds the rpm at 4000.

I just left the cables disconnected, I believe on 750s the overheat sensor is normally open and the circuit closes when it overheats. On sxrs I believe you use a jumper because it advances your timing 6 degrees right away

You are correct, according to the manual there is only one and it is indeed an open circuit until it reaches 203F and doesn't open again until it drops below 190F.

Here is the complete manual if you don't already have a copy.

Did you get the ski running propperly again ?

Did you get the ski running propperly again ?

Priorities changed for a while and I strayed away from jet skiing but I'm back again.

No, I never got it fixed and I replaced every electrical part of the ski and the carb, so I'm still stuck. I'm going to drop it off at a mechanic for the winter and hopefully I'll have her back up and running for the spring without my emptying my pockets

Well I figured mine out! It's embarrassing but it was a broken baffle in my waterbox

Funny that one of the first post was about the waterbox. What a pain !!

 

[Radcon15]

Well the new season is starting and I still haven't gotten this figured out. What symptoms would a broken baffle in the waterbox have? I think I'll start checking out the bottom end and see if maybe the crank seals do leak. It'd be great to fix this for memorial day

Been a few months...Any luck? Or did you finally set fire to the mother f*****?!?
