Double Bubble vs Flip Up (touring) Screen

[bwizz]

I made myself a mra vario from using a cut down top of an old screen , and vario hinges bought from the mra importer for around £25 this works very well on my foxeye 600 , works much better in fact than the genuine vario which I have on my gen1 thou, although the bikes and screens layout look the same , they are quite different on the two bikes
