Rifle fairing for Gen 3's

[dcarver]

Dropped Naomi (2013) off at Rifle Fairing this morning for fitment. Gary Patel has dropped all employees except for Dennis. Gary is now the 'production' guy. 

Will keep thread posted as time rolls on and R&D completes to prototype stages.

Way to go Don!!  Had a Rifle on a 2007 and was bummed to see they didn't offer one for the Gen 3 or Gen 4's,  will be following.

2013-08-25 2013 FJR Wind Screen Story (Naomi)​

Naomi came with stock OEM screen and Cee Bailey 'Laminar Lip'.​

Laminar Lip blew off.​

Then realized how much the stock screen sucked.​

Contacted Gary Patel at Rifle, Atascadero.​

Gary used my 2006 to template Gen2 'tuning blocks' and windscreen, which work incredibly well.​

Gary was interested in templating my Gen3 so dropped the bike off and Gary went to work.​

First up, some pics of the very successful Gen2 setup.​

Looks like screenis in down position.
(took pics weeks ago!)
​

Front view.
​

Up position. Note that as the screen raised, it becomes more vertical.
Poor design, mamaYama.
​

Up position front view.
​

Up position side view.
​

Height measurement.
​

Prototype Gen3 screen and 'tuning' blocks.
​

Up position. At this point of time, have not ridden to test.
​

Cockpit view.
​

Tuning blocks are 3D printed prototypes for testing.
Not sure if Gary plans to keep 3D or machine from aluminum.
Machining cost $$...
​

Another view.
​

And again.
​

Not as nice as Gen2 blocks..
​

.
​

Air gaps look ugly.
​

Screen appears very vertical in full up position.
​

And that's with 1/4" spacers under lift mechanism bottom points.
​

Tubing cut size.
​

.
​

Hmm. Very vertical. Starting to wonder if too vertical.
​

Full down position is not as 'layed' back as Gen2.
​

Riding Test​

Took Naomi out for test ride, 341 miles, and it simply sucked. 
Severe buffeting, eyeballs shaking hard enough difficult to read street signs under some conditions.​

Sounded like two rock n' roll drummers pounding on either side of helmet too.​

Standing on pegs in clean air much better, but even that's too loud as compared to Gen2 setup which has a nice
pocket of quiet with screen approx 30% up. Recall the screen becomes more vertical with lift, so the idea is find 
the quiet zone at height the rider normally uses. For me, I like a little wind on chest to eleminate wrist fatigue, which
equates to looking over screen top by about 2 inches.


Decided to make some temporary 'tuning block adjusters from wood shims, to experiment.
15.5 mm at fat point.
​

6.2 at skinny point.
Glued shims together.
​

9.35 mm thickness delta, top to bottom of shim.
​

Whichis nearly .4 inches.
​

Will it be enough?
Stay 'tuned', no pun intended!  ​

Called Gary, let him know more work needs be done. Gary confirmed and stated after re-running the numbers the screen needs more angle and is working on rev2. Hey, that's why it's called prototyping, right?​

Gary is a department of one, "Get a man right on it!", but said he'll try to have rev 2 ready before I leave for Tyler's Virgina Creek Settlement run and RR10.​

In the meantime, purchased a Yamaha touring shield from PartZilla as a 'plan B'. It's here now. Spoke with Bill Lumberg from FjRiders.com, he has tested a bunch of screens. Naturally curious, I guess.​

"I’ve used Cee Bailey, Aeroflow, all three vstreams, and the Yamaha touring. The Yamaha touring is probably the best all around, for me.
The Aeroflow is notably good, but leaves bad helmet battering at higher speeds for this 6’0’rider, 32” inseam, that uses a helibridge in the middle position.
The vstream 20308 was probably a close second."​

Installed OEM touring screen and test road today. It works very well. I did shim the bottom about 1/4".​

Pics to follow. ​

Pics out of order, sorry. 
First attempt at home-grown tuning block adjusters..
​

Starting point.
​

Glued together.
​

Installed. Unfortunately, I dorked up the other side and had to build another adjuster from scratch,
While the glue cured, installed the OEM touring screen.
I told you this was out of order.. 

​

Preparing to install OEM 'touring' screen. Got these nice spacers from local hardware store.
​

Decided to stack two of the smaller spacers. Not the bracket wants to bend to conform, so just enough torque to hold..
​

Close up view.
​

Front view.
​

Front, screen up.
​

Side, screen up, much more 'angle' than prototype.
​

Screen down. this might work, pretty close to Gen2 Rifle angels.
​

Close up of upper position.
​

Getting late, Duece, neigbor dog, supervises.
​

Long of short, this configuration works very well per 80 mile test ride.

Full down position equals clean air flow, same as sticking head outside the bubble.​

Full up and some buffeting, but no rock n' roll drummers.​

Mid position is the sweet, sweet spot. Quiet, almost as good as Rifle Gen2 screen with tuning block.​

There is one spot where my duck-billed helmet has some downforce, but it's only for approx 5 or 10 degrees.​

All in all, the Yamaha touring screen works very very well.​

It will be fun getting back to prototyping the Gen3 Rifle with Gary. Hopefully the product will excel and be better than the OEM touring screen.​

More later.​

All for science. Nice write up. Look forward to hearing your continuing R&D.
