I have a 1996 SLX 780 that I bought from my neighbor. Last season he said he was having problems with it throttling up to full throttle. After messing with it, I found that it will rev to 6700ish rpm on the trailer with a garden hose hooked to it, but when placed in water, it is limited to 4300rpm. I have replaced all the fuel lines, replaced the fuel/water separator, bypassed the the fuel shut-off, rebuilt the fuel pump, rebuilt the carburetors, new spark plugs, battery and replaced the CDI box. The unit starts and idles with no problem. It is just doggy getting up to 4300 rpm, and then it seems there is a rev limiter that kicks in. The MFD works fine and displays the fuel and oil levels appropriately. There are no other warnings that are displayed.
Could it be the low fuel/oil heat switch in the electrical box? Not really sure where to go with this anymore and don't want to replace parts if not necessary.
