i recently purchased a 2004 400at. the guy that had it before me said that it was messing up shifting and the angle sensor was replaced. i got it home and within a half hour, the neutral light started cutting in and out. The next day it was on all the time. Later that day shifting issues began and went home in limp mode. im guessing that the angle sensor was not the issue. i replaced the beutral switch down by the shift motor. i noticed at the time that the rubber boots that cover the switches were all cracked, so i replaced that harness. Needless to say, that did not solve the issue, and i did not think it would. Im thinking electrical/wiring problem. ive noticed also that when i hit the rear brake lever the neutral light dimms slightly (when the bike is in drive). The issue dissappears every morning, but after it warms up the neutral light starts staying on again. The bike still drives and shifts as it should most of the time and sometimes the neutral light will go out for a while. The bike has not had the shifting issue since i replaced the harness and neutral switch, but i have only used it for a few minutes; therefore no error codes. Anyone have an idea where to start looking?
