Little plastic thing . . .

Postby wh0382 » Fri Oct 11, 2013 9:07 am



I've asked at three dealers and they do not know. What is that little clear plastic wing-spoiler-thing above the valve covers?

I have been told it is supposed to deflect water that channels to that area when you ride in the rain.

I use it to flex the panel in and out to line up the stud on the side cover with the slot in the panel when reinstalling it. I just thought that is what it was for.

Honda calls these things spoilers. The part numbers are: 83580-MCA-000 for the left side and 83530-MCA-000 for the right side. The retail price is $4.67 ea. Hope that this helps.

Strangely that deflector also has a noticeable impact on airflow in its absence. Have not removed and tested but the discussion and its evolution to the GL1800 related heat wrapping around into the legs and cockpit area. Still it would similiarly deflect some rain splash I suppose. Seems so insignificant but its absence was notable in the article I read. Maybe I'll remove and see if I do get any radiator heat to flow (its cold here!).

I've been told that its purpose is to keep air from getting under the side covers and popping out of their grommets and thus getting blown off.

I'm missing one myself and nothings blown off so far.Can't really see any difference form one side to the other as far as air flow.


If I'da known it would last this long,I'da taken better care of it.
