Hello! Can anyone tell me what these wires are for?
My bike also makes a buzzing sound when I try to turn it on. Trying to figure out what's causing that
Unrelated but your chain looks pretty bad. You should clean and lube it at the very least.
Tell him what he's won Johnny!!!!!Trepetti gets an A for correctly identifying the O2 sensor. The buzzing sound could simply be the fuel pump priming.
