Hey everybody! I just signed in to this forum, I am a new, happy XT66Z, 2011 owner. I have the bike since March (2014), so we are still experiencing eachother

. The bike has an aftermarket, black windscreen, and I feel some naughty airflow on high speed (over 80 km/h) which is really shaking my head.
Do you have any ideea, which is the "perfect" windscreen to minimize this bad airflow?
Somebody told me that this airflow is coming from under the free space between the tank and the light. How can this be resolved?
Thank you, I am confident that I will find only good ideas from here!
PS: Sorry for my bad english!
