Some of the guys on the RGV forum have bought these Hong Kong fairing sets (not this seller). Feedback seems mostly good on quality/paint etc, but various levels of fettling have been needed as holes and bosses have been not quite right. It's not just the Chinese suppliers. The French seat unit I used on my SV was an appalling fit.
If your current plastics are OK, have you priced up a respray? You must be a good bit of the way there by the time you've bought that kit and had the tank sprayed. OEM plastics are normally streets ahead of aftermarket stuff in terms of quality. They usually fit quite well too.
