Hi guys, I have snapped the indicator off my YBR125 and need to repair it. The indicator is working fine, just the mudguard holding it on is snapped. I've brought a replacement just don't know how to fix it. It looks like theres maybe three bolts holding the rear fender/ mudguard on but they are in a difficult position to reach and they've slightly rusted. Is it possible to replace the mudguard and rewire the indicators myself or am I best taking it to a garage?
