I decided to see if I could do something about better commuting comfort on my 220F.
So I fashioned a cardboard windscreen which I bolted on over the existing screen using the original screws and took the bike for a spin... no more wind on the chest!
The next step was to buy a suitable sheet of 3mm perspex and make a mould. Building a box from masonite I mounted the cardboard windscreen, (still bolted to the original, now suitably covered in cling wrap) in the box and pumped foam into the box.
After cutting the perspex from the cardboard template, using a paint stripper gun for heat, I tried to form the perspex into the mould - did not work too well. The next step was to cut another cardboard template, place it into the original mould and fibreglass it. Draping the perspex over this and heating with the gun worked really well although to get a better conformance to the shape the original mould was also placed over this with pressure until all cooled down.
The screen was then screwed on to the bike and heated to normalise the perspex. The upper edge of the windscreen went out of shape so a wooden shaper was clamped on to the top edge and the screen was normalised again. This had the pleasant effect of giving the screen a "bull terrier" profile which I think looks cool!!
Hopefully this screen will not only provide better comfort while riding but better fuel consumption as well...
