I was messing around with the xb-600 today and was trying to get a feel for the speed zones of the throttle and the in-between zone of the right brake. I did learn a bit and will know somewhat about the areas on the throttle to maintain speed instead of gunning it every time. I've found there is a sort of hum after it reaches above or close to 20mph, but below there isn't as much of a hum. This is likely information you may already know from riding the bike, but I'm just recording what I know about the bike so far. However, while alternating between stopping the bike and trying to find the zone in between I've somehow blown the wire or the circuit that controls the right brake light. Granted I would never use one brake at any given time, I'm curious to know what could've gone out or blown in the wiring. The bikes brake lines work fine for both wheels and actually follow how a regular motorbike or scooter is supposed to work, and the bike is still fully functional but for the brake light.
The question is what could've gone out to make that happen?
