The Genuine Yam screen rubs the fairing and Will wear unsightly grooves in it, I had one once and spent a good while filing it back so it cleared the fairing, went out for a ride and it made so much wind noise I had a headache even with earplugs in, took it off and sold it. I found the standard screen the best compromise although I've ridden one with an MRA Vario screen that is about the same size as stock but has the pull up bit so you have options and it still looks good.
