Hi Charlie see a pic of mine below
I didn't do the work I bought it like this however I do believe it is quite simple with most street-fighter kits coming with clamps etc. Wiring would be the only mess on
You don't even need to buy a "streetfighter kit", just take a few measurements of the width of the Forks, towards the top (with front fairing removed).
Then look for a suitable Light unit that you like. Ensure it has the necessary mounting points on the sides, for a set of Fork brackets, to secure it in place.
Having lost the original fairing, you'll then need somewhere to mount the front indicators. The said fork brackets often have holes for mounting aftermarket indicators too.
There's so many ways to do it, start by carefully removing your front fairing (which you could put back on if not happy - or sell, to recoup some funds towards this these modifications), and see what you have behind, plus commence from there... Headlight wiring loom would also likely need tidying up, as it'll be long, to reach through the fairing for the Lights.
