MRA-Xcreen Update -- Wing Position and Air Flow

Just a quick update here.  I had a chance to take the bike out for a couple of hours today and play with a number of different positions for the wing on the X-creen.  I had originally been riding with the support arms pretty much straight up 12 o'clock with the top of the wing angled slightly backward since this is how it appeared in the pics from MRA.  This worked pretty well, and after installing the spacers, it even seemed to work better.  After several starts and stops to test various positions, I've now settled on having the support arms positioned so they are pointing directly forward with the top of the wing angle back so it's almost, but not quite, parallel to the primary shield.  It's probably about two clicks away from being parallel.  Sorry, I didn't take any pictures, since it was a trial-and-error process.  If you want a picture of the final position, leave a comment, and I'll go take one and add it to this post.

It was fairly windy today, with the winds blowing out of the south, so I was able to test the position with and without a headwind as well as with crosswinds.  This new position seems to push the air high enough that the air intakes on the top of my Shoei RF-1000 can catch it, but it leaves the helmet itself alone.  I'm not sure, but I think this works better than the original position due to the wing being further forward.

I have also come to the conclusion that the primary source of any buffeting is now the mirrors.  Installing the mirror extenders helped tremendously, so I may experiment with angling the mirror stalks in a little more to see if that helps.  I also considered buying some Saeng Micro-Swirl Generating Edging and putting it on the front of the mirrors to see if that helps.  Then again, the temperatures are quickly ratcheting up into the 90s, so it's probably worth it to have a bit of wind for evaporative cooling.

UPDATE:  At the request of Mark Collins, I took a picture of my current wing position setting for your reference. As you can see, the support arm is pointing directly forward, almost parallel to the ground.  The wing is angled at about 45 degrees from the arm, which gives it a little upward angle relative to the primary shield. In case you missed it in the original X-Creen post, I'm 6'-0" with a 32" inseam, so your mileage may vary with this setup.

MRA X-creen Re-mount or "Oops, need to RTFM!"

So here's a bit of a lesson in RTFM.  That would be Read The Farkle's Manual in this case.  Now in my defense, I didn't read it, because I didn't know about it.  If you read my original post, you'll know that I bought this screen second-hand from a fellow Stromtrooper.  When I opened the package, all I saw was the windshield itself, so I figured it was just a direct replacement, using the stock screen's screws to mount it.  Apparently that is not the case.  As I was throwing out boxes that have accumulated, I was separating out the packing material that could not be recycled, and lo and behold, there was a plastic ziplock bag at the bottom of the box with... you guessed it... the installation sheet and some parts!

The mounting parts are essential for proper fit.

The parts baggy included two 15mm plastic spacers, two 10mm plastic spacers, washers, and longer screws with which to mount the windshield.  Interestingly enough, I was contemplating going to the hardware store to look for these very items to see if that would help move the wind off the top third of my helmet.  I installed the parts today before I went for a ride, which took all of 15 minutes.  The key to  installation is to put the washer on the screw, then insert the screw through the front of the windshield.  On the back side of the windshield, put the spacer on the screw, and then put the well nut on the screw and turn it 2-3 times to keep it from falling off, but not far enough to compress the rubber.  The two long screws go with the 15mm spacers in the top holes.  The short screws go with the 10 mm spacers in the bottom holes.  Once all four screws and spacers are installed, it's a simple matter of pushing the well nuts into the holes in the fairing and tightening them down with the included allen wrench (3mm).

I was very surprised at how much of a difference it made.  I can still hear some wind roar with my ear plugs, but I don't really think that's going to ever go away, but the main thing is that there is minimal turbulence hitting my head now.  I had been considering trying out a Parabellum windshield, but I don't think that's necessary any more.  The main reason I know it's made a difference is because there is quite a bit less wind noise being picked up by my helmet-mounted Drift HD.

I still need to play around with the angle of the spoiler, though.  I angled it back two clicks from the straight up position, and it seems to have improved things a little bit.  I'm going to rotate it forward one click to see how that changes things, or perhaps rotate the arm forward to move it down and out front a bit more to see what that does.  Overall, the proper mounting pieces have improved this windshield, and I thought it was pretty good to begin with.
