Larger windscreen for C650GT

From the mpg thread

.....I lose about 3-5mpg with the Aeroflow. Plus it bounces around like kahrayzee when hitting truck turbulence. I may put the stock windshield back on to remind myself of why I made the switch. :)
 
I think my milage may have gone up a mile or two and just got back from the White Mtns. In NH I was glad to have the shield while traveling down I 91 at 80 mph plus had no wobble it really makes a big difference on long trips we did 900 miles over 5 days there and back did quite a bit of hiking and eating while there.
 
I definitely noticed a 3 mpg reduction at the lowest position. Fully up it's -5 mpg but for those occasions there is good reason. One, my wife wants up it to keep air off her in the back. Two, trying to manage a phone call and keeping it quiet.

As a side note, I've figured out the Bose noise cancelling in ears work to make the ride super quiet. But they do stick out a bit so I have to make sure they are adjusted.

The CalSci does not bounce around. It is really stable itself even around trucks, and stabilize the bike vs. the stock "sport" model that came on my GT. Hmm. Do all Aeroflow's do this? I was thinking about getting one to discharge my nervous energy that comes from reading this forum about all the stuff I didn't buy...
 
I haven't noticed my Aeroflow shaking any more than the original stock screen, even around trucks. One thing I have noticed with the Aeroflow is that I don't have to raise it as high as I did the stock screen to avoid turbulence. The flow over the screen is ALWAYS smooth so I don't get any helmet buffeting. That leaves me free to raise or lower it based on how hot or cold I'm feeling rather than just to eliminate NOISE.

Since that means I normally leave the Aeroflow lower than I did the stock screen, that MIGHT explain why I'm not seeing any change in MPG (and also why I might not be noticing any "shaking" either).

Hmmmm, that is the same thing I have experienced and is one thing I did not consider when I talked about my lower mpg. It is something I do now that I did not do with the stock windshield.

With the Aeroflow, I do actually use the electronic adjustment and it makes a big difference. I wonder what I am missing because while I get lower mpg there may be a factor that I am not taking into consideration. Regardless of mpg, I am VERY glad I bought the Aeroflow.
 
I bought the large size Aeroflow before I ever really established a mileage basis. However, my mileage has been slowly creeping up and has been 54-54.5 the last several tanks, as long as I avoid the interstate.
 
To further the mileage aspect - I've noticed the MPH is different on the bike vs. the GPS. Usually 2 to 4 MPH faster on the bike than GPS. Same with cars I've observed. Do we think the MPH is "real" on the bike? I've heard all kinds of variations on accuracy.

On most sport bikes the speedometer reads pretty high, usually 7%. However the scooter its within 1 mph at less than highway speeds, and within 2 mph at speeds over 70. Fairly accurate...
 
I have only "tested" mine when on those radar signs we see once in awhile and I believe mine to be within a 1 mph or so accurate, also. The KLR is off by a 2-3 mph at lower speeds and a little more at highway speeds.

Once I get over a 100mph on either bike I just close my eyes so I have no idea how accurate either speedometer may be at that speed.
 
BMW windshield works good for me.
Speed, GPS 40 bike 40, GPS 60 bike 61, GPS 75 bike 78. Yamaha FJR 5 off at 75, Bergman 650 off 10% up and down.

I thought the purpose of those "Radar Signs" was to see how HIGH you could bump the displayed number. Was I mistaken??

I did that at the radar speed sign to see how fast I could get it up to didn't notice the cop in the unmarked car behind me and got pulled over I said it was a new bike to me and wasn't use to it and so on and he was asking me about the bmw 650 gt and how much it cost etc. any way he didn't give me a ticket good thing I turned the bike off and he did not see that I had 14500 miles on it.
