I am doing some work on a buddy's 86 XP 787. The problem is it won't rev up past about 3000 RPM. I thought it was a fuel delivery problem so I cleaned the fuel filter. I also took the carbs apart and cleaned everything out. They weren't dirty at all. I checked the pop off pressure on both carbs and they were at 38psi which is in the OEM range of 23-42. If it idles for a minute or two it will fully rev up for about a half a second then it slows way down and acts like a rev limiter is set way low. Very strange.

On another forum I found that people were finding that the rectifier was causing this. I installed a new one and sure enough, it fixed it.

Put a meter on the battery and start the ski. Rev it up to 5000 rpms. The volts shouldn't read over 15vdc if it's over the rectifier is shot and if it's lower than 13vdc it's junk also.
