if its the sport then there is a small negative terminal block inside the cowling that can fur up. it has a black plastic cover over the top of it with a small clip on the side. remove the cover and inspect the connectors (there is a metal bridge piece, pry off and clean) on the block and apply acf-50.
also the main loom to sub loom connector inside the cowling terminals are notorious for furring up. again apply acf-50
each of the above requires you to remove the whole headlight cowling to gain access to the connectors. on the final removing of the cowling you have to hold the cowling in one hand and undo the main loom to sub loom block at the same time or the cowling wont come off. no need to remove the screen.
when putting the cowling back on
remember to connect the main terminal been there done that
