I installed the 4" risers today and when I did I removed the headlight for easier access. When I plugged everything back together and turned on the key the right front and rear turn signal are illuminated while the left is not. When I activate the turn signal switch on the handlebar, the left one works fine but the right one flashes real fast. I did no other modifications except add taller risers. Any ideas what I did or how to fix it?
