Hey gang,
I finally took my 2001 KLR650 for a well enjoyed & overdue long hwy & back
road ride, (Ramapo 500 try it yourself next year) I've mostly been doing
urban assualt these past 6 months great against the pothole & road
destruction. Like the VW ad says "NY, NY named twice, paved once."
Besides wringing the guts out of it and needing to touch redline more than
once to keep near my riding buddies on (street bikes) [I should also mention
that the both hold AMA/club expert level racing licenses] and/or to pass
very pokey 4 wheels. The bike was great (but all you know this already) I'm
still learning it and I understeered a bit as I'm accustomed to a quicker
turning bike, plus wasn't quite used to the large wheel & fork angle, It
only really mattered at elevated speeds on/in the twisty stuff. I'll
practice more.
The Problem I found was wind noise, yeah I've learned from this list that
there's no perfect windshield and when I stood up the wind noise
disappeared. I removed the clear part of the 'shield and that helped some,
mostly with the buffeting. So I figure that there's some part of the built
on fairing that causes the noise.
Details & factoids:
I'm 5' 8" tall, 160 lbs, I don't require long/tall or short shirts or
jackets (shirt size 14.5 X 32, jacket 40-42) so I guess I'm regular in body
proportions.
I wear an Aria Signet GT helmet, usually using earplugs (even with, this
noise was loud & detrimental). I've replaced the bars with less wide and
lower (to make urban riding easier & fit me better) I've also lowered it
3/4" in the front + about 1 " in the rear, to help make backward-walking
parking easier.
With and without the clear part of the fairing the noise went away when I
stood on the pegs or got out of the bikes airstream. without the piece the
noise builds from 60 mph & is quite deafening at 80+. With it seems to
start around 40-45 mph & builds. I'm currently using it without & the only
problem that that creates is a loss of a place for my E-Z pass (mostly a NE
thing)
SOOO, what have YOU been able to do to knock out the noise (no riding on the
pegs always is not an acceptable option and just accepting it isn't one
either.) Changed the shape of the fairing? A wider cut down 'shield?
winglets? Better ear plugs? noise canceling technology? adapting
windscreens from boom microphones?
I'm trusting some of you have gone thru this already & can save me the
massive part of problem solving process.
Thanks,

I'm the same physical size as you, and had similar issues.
I put an Acerbis fork-mounted fairing on my bike, it moves
the edge of the windblast to mid-chest, still functional on
the highway but quieter.
The other option is to set up the fairing in "beater"
configuration, so named after Mark Van Horn's beater bike.
Remove the plastic cowling, cut down the turn signal stalks,
and the bike looks sort of like a streetfighter. Looks best
with one of bigcee.com's headlight grilles.
The cheapest option, is to simply start trimming the top of
the stock fairing until it works. You can get replacement
fairings from dual-star.com most of the time, pretty cheap.

Carl,
In days of yore when I was riding un or half-faired bikes, I always wore earplugs. I joking said that, when 70, and my wife started whispering sweet nothings in my ear, I wanted to hear it.
Well, I'm now at the stage in my marriage that I *know* that ain't ever gonna happen, so when I started riding a Concours a number of years ago I found that I really didn't need earplugs. My helmet was an Shoei RF700, is now an Shoei RF800, and I always ride with the shield up, even in the winter. The only exception is when it is raining or snowing.
I bought a KLR in January and during my first blast (60-70mph) down the freeway to work I found that the wind noise was unbearable. That evening I dug out my old stash of ear plugs and started using them when riding the KLR. I store them, and extras, in a film cannister in the rear pouch of my Explorer. Not sure whose they are (will look tonight), but mine are a soft, orange, rounded plug looking type that do an excellent at blocking 98% (guestimate) of the noise I had been hearing, again this is with the shield up. I had tried the cylindrical shaped earplugs (EAR) in the past, but they didn't hold a candle to the ones I am using now.
The fairing and the shield on the bike are stock.
I'm no expert, but my money's on the helmet (some are more noisy than others), and the earplugs. Since the latter is the lesser $$ of the two, I'd recommend trying different types to find one that works the best. Also, proper insertion is key in how well they perform. The ones I use need to be inserted deep into the ear canal to provide the optimim noise cancellation. I can tell immediately once underway if I got lazy and didn't get them in correctly, or allowed them to 'crawl' back out as they expanded.
Sorry. Got a little long winded there (no pun intended).

Here's a photo of my A2:

I also did this on my A3. I took an old helmet visor & used it as a
template, traced with a marker, whipped out the Dremel tool and then
put door edging on the top edge. I cut the shield down about 4".
Looks & works great.

Used to be the rubber blade from a big squeegee.
I'm told the aluminum from road signs is ideal for
motorcycle bodywork.

Believe-it-or-not... it's a bona fide KLR aluminum bash plate, one of
the earlier styles without side protection. It's a bit FUBAR since it
assumed the shape of the engine & frame twice and I had to bring it
back into shape with a 20 lb sledge. That's why you may have mistaken
it for a coal shovel.

OK... with a little more research I found the
DECALIFORNICATION procedure I was after. If anyone has
insight or comments on the steps involved, please let me know.
Thanks,
