Lower fairing vent upgrade

So, it's been cooking for 39 years and is still not "done"?
My thoughts, but It does only have 35,000 Km ( 21,000 miles )

This picture shows the large vented area in the lower fairing. Where do you plan to drill holes?
The 1980 brochure seems to suggest that the RT had louvers on the lower front fairing.

Most likely the reason is that the image is too large. Try reducing the size down to below 2Mb or to a pixel size of 1024x768.

Well it's tough. After my most recent failure to post pics, I had my tech do a house call and he set up a function whereby I can right click on the mouse, with the cursor on the picture, and a sizing window will drop down. Then I duplicate the picture to "large" (I think) and then paste it into the site. He created a check list for me for image transers from Smug Mug to here, and I figured out my own checklist for computer to here.
But recently it quit working again.
It's been part of my lifelong struggle with image management....
Back to the topic: I did find a picture in Bill Stermer's book of an early RS with an almost solid front fairing panel, with short louvers on each lower side. Maybe the RT had these too.

It would be interesting to do an oil temperature comparison between bikes having the earlier and later centre panels. I suspect there wouldn't be much difference, as most of the cooling would occur at the cooler and the outer cylinder heads.
And most of the high heating would occur when the bike is idling at a stop, when air flow isn't a factor anyway.
But it was no doubt an easy modification for BMW, so worth doing.

Here's a recent discussion about likely changes on the SmugMug side...seems you have to clickey some new things.

You can see the short louvers in post # 10.
There were at least two variations of the center lower panel on both the RS and RT airheads. One was “fully-louvered”, and the second was mostly solid, with openings only for the oil cooler near the top, and two very small sets of louvers near where the bean can resides behind the front engine cover. There may have also been two variations of the fully-louvered lower fairing panel for bikes that, at first, had no oil coolers, and a later version which did have an opening for the oil coolers. I remember that there was a concern that the near-solid center panel did not provide enough cooling airflow to keep the electrical components behind the front cover happy. No personal knowledge about whether that concern was valid. Rather than hacking up a solid lower center panel, there are lots of louvered ones available from the usual parts sources. New ones may still be available from BMW.
