It's Friday lunch time and I've been out on the bike to see if all the work was worthwhile. It wasn't.
It was so bad I had to come home and make a toasted bacon sandwich to cheer me up. I had taped some telltales inside the screen and then went out riding. Once again the telltales all pointed downwards and rolled around as the air coming over the top of the screen overpowered the air coming through the vent. Perhaps if the vent were higher it might have been able to generate some inside uplift. I was also reminded of how bad this screen is for wind noise and buffeting at head level. The constant crackling of the wind around the helmet meant I was glad to get off the bike. So it's thinking time again. The next plan is to cut it down a heap. Now that I know how easy the stuff is to work with I'm not worried so much about cutting into it. It's currently 60cm from the headlight cutout to the screen top. I can cut it down to 40cm easily. This will give me spare stuff to experiment with making a movable spoiler that tilts to the front a little and push the air upwards. It takes me time to think through these things. I'll let you know how the next step goes.
