I dropped my ybr the other day when I released the clutch too quickly with the throttle up too high at a gravel parking lot. The starter switch fell out and the pin disappeared. I'm therefore jumping it with the spring at the moment. PITA Not being content with the fact it doesnt have a kill switch, which is slightly annoying when stopping at long lights as the ignition is a bit janky and the key doesnt turn beautifully, I am hoping to install one tomorrow. I have bought one which has five wires which have no indication of what they do. I could really use some help! Thanks in advance. Bit out of focus but it displays the wiring colours.
