I use a Califirnia Sport Windshield I bought from Harper's. Small but by far one of the best solutions and NO buffering!

Swanee Aerofoil. Ugly as a sh!t sandwich, works marvelously.

I use one on my red/black Cali and me thinks it looks good. to be honest if someone is wanting the most wind protection they can get on a Cali bike the Swanee or H & H from Harper's is the best! now if you are looking for that "Hog" look well.....

  I spent many hours on the slab at 85+ miles an hour.  The only thing that worked was this H&H fairing.  If you are going to put some miles on one of these bikes, just spend the money and get it over with.  I'm riding a Norge now but still miss the CalVin for long haul comfort.

No mods needed. Most bikes with round headlights the same windshield will fit regardless of brand, year or make. The shield is attached to the handle bars with brackets and same with the mounts on the forks.

Not true for my bike.  The replacement PF3 didn't fit around the turn signals and other controls.  I forced it on and bent the plastic.   But it did work. 

I decided to take it off and modify it for a better fit when I dropped it and broke in two.  I replaced it with the PF2 (the next smaller one) and it buffeted terribly.  I was able to reposition it and made acceptable.  There is thread here about that.

If I knew the Honda Shadow model PF3 fit my bike, I would've ordered that one.

  One thing I found out after installing the H&H fairing was that the fuel tank is too small for long distance riding.
I was never ready to stop when the low fuel light came on so an additional three gallons made 1000 mile days  much more doable.
I don't push that hard anymore and I'm mostly ready to stop when the Norge is empty.

From the piece I have cutt off of my second windshield I have created my homemade "Laminar Lip".



I will test this solution next week. The 3M Duo Lock pads should stay untouched for 48h if possible.
I must admit this looks ... strange...

Could you make a California Sport windshield by cutting down the stocker?  Harpers wants big money for theirs.

I am just doing this for my own stuff. I can understand why they charge much. It took me approx 2-3 hours to cut the screen and grind it.
Aren´t there other options in the US? E.g. Rifle?

Jan my friend, you are killing me.
I had A perfectly calm pocket of air on my Calvin With two simple add-On’s, a taller shield and a simple pair of 70.00 lowers for an 03 FLH Harley and simple to add on. Lol, you need me to hop on a boat and come fix it for you?👍😄😄

@ Danny  :grin: ... I just had to do all this ...it was floating around in my head for two years now.
A new (wider at the the top ) windshield and maybe lowers (I do not like the looks) are the next options.  :wink:
You are always welcome.

I just test rode the CalVin with my "homemade Laminar Lip" yesterday. The buffeting and the wind noise is a bit less but I could not feel a difference to my test-setup with tape.

My previous '98 V11 Cali had the OEM "Barndoor" screen. As most of you already know, it is basically a big buffeting windpusher, I was never satisfied with it. I now have another '98 that is fitted with a Wixom fairing. Happy to report that it works pretty darn good, minimal buffeting and very little turbulence behind the screen.

 It is a bit taller than I would like, but I am reluctant to possibly screw it up by cutting it down.

I did it ... I just testrode the "Danny Solution".  :thumb:
You still have some wind noise comming from the upper part of the windshield
BUT the buffeting is now completely gone. No headshaking  even at high speed.
My shield is in the most upright position and my "homemade Laminar Lip" is not mounted.
For the first time I drove the CalVin at 130-140 km/h ... nothing!  :thumb:
You can even drive w/o glasses wearing an open face helmet.
You need HD OEM 58121-85B deflectors or replicas of that type.

Thanks Danny (Ncdan) for this idea!

You do realize this issue could have been fixed nearly 2 years ago, right😂😂😂
You can’t hardly even notice they are on the bike, blends in beautifully.
Glad you got her fixed. The first time I test rode mine after the installation of the HD wind deflectors I simply could not get the $#|+ eating grin off my face👍👍

What should I say ... Yes I was an idiot.  :laugh:

I wasn´t willing to drill the holes but I got hold of a pair of used holders as a backup and I wasn´t sure if I like the look.
I must admit that I like the look and it fits to the design of the vintage.

I have used curved stainless steal washers with neoprene rubber and nylon washers to mount the deflectors (refer to the photos).

I saw that with the rubber backed washers and that was I great idea. I had some rubber washers on hand when I mounted mine as it definitely reduces the vibration therefore reducing the chance of the shield cracking. Your end results are great, very professional looking 👍

  Wind buffet - low pressure area behind the windscreen and air flowing up from the bottom of the windscreen hitting the fuel tank. Eliminate the low pressure area and redirect the lower airflow.
  I made some lower wind deflectors for my Jackal that had a barn door windscreen for about ten dollars. The opening for the headlight was enlarged above the light to allow air up the back of the windscreen. The lowers directed airflow around the tank and up behind the windscreen. I could ride at 70 with my face shield open and with just enough airflow to keep me cool on a hot day. Easy and simple.

I’m not sure about the CalVin but the Plex3 for the Honda shadow fit like a string Bikini on a chubby girl on my 2004 cal EV🤣

I just put the H&H fairing on my California Touring. I ordered the tall windscreen.
I'm 6'3", and maybe I need to trim that. (No sense pushing more through the
wind than I need to.) But I could read the newspaper behind it now. At 70+ there IS a moaning noise, though.
Gotta figure that out - it's mildly annoying, but not in the same league as the
buffeting. That felt like I was a human speed bag......

The only buffeting now is way down low when my feet are on the highway pegs. Everything
is fine with the stock foot boards.

Now I have to take it all off and paint the fairing to match the bike.

The Corbin seat is a big improvement over stock, too.

It wasn't a California Sport windshield, it was a California - Sport Windshield.  I bought it 'used' off fleabay and had always thought it was OEM Guzzi.

I have the same one on my 02 Stone Metal, and it buffets BAD.  Ive been messing around with different angles a bit, and "kinda" got it useable now. Might be just a different mix of seat/bar/rider height that makes it work better for you.

Make sure you leave two finger widths between the top of the headlight and the bottom of the screen to allow air to flow under the screen.  Without this gap the air being sucked into the vacuum left by the windshield pushes the rider's helmet around.

After years of me fiddling with the stock shield in an attempt to stop the buffeting, Jim Barron at Rose Farm set me up with a California Sport Shield on the CalVin and I couldn't be happier. I get no buffeting for the speeds I typically run the bike at 45-70+ mph.

I also added Memphis Shades lowers to the fork which cut the upwind draft significantly.

This bike is my favorite goto for taking relaxed day rides.

My Norge is still my go to for any long distance touring.

I would like to chime in and say that I installed the HD / Replica's Wind Deflectors on my Calvin today. Ordered them from Lion Parts.com   -  a couple of days ago, and they were delivered this AM.   $75.

Did not have any issues or surprises on the install.

Raining today, and have a ride planned for tomorrow.  Let you know how they work, with the original windshield.

I’m sure you’ll love the calm pocket of air, it took the better part of an hour to get the grin off my face when I returned from the test ride after I installed mine.
Be mindful in that I also had the larger tourer windshield on mine also.
I helped with the design of that shield for CLEARVIEW Shields also to add the Calvin to the their models application.
