When I installed my Puig, it came with a warning about lensing potentially causing damage. I assumed it was a CYA and went ahead anyway, because I've had an after market windshield on all my prior bikes, including a Puig on my R100R. But then one time last fall, when it wasn't even very hot out, I stopped at a coffee shop for about 45m. When I rode off again, I noticed the LCD display was totally black, and then slowly faded back to normal over the first couple of miles. The only plausible explanation is heat caused by lensing. This thread seems to support that theory. So I guess I'll carry an old TShirt around with me to put on the windshield from now on.
