I have a just jap kit. Mechanic said it was the worst he'd seen mostly because looks like that particular one was not packed correctly and with a call to the Just Jap guys it wasn't and they were really good about it. No brackets, wrong bolts, couple of wrong size joiners and shite clamps. Took my mechanic 7 hours to make new brackets, move everything and fit it up without cutting the front bar (400R) or the fan only the hole for the pipe and a little out of the airbox snorkal so I'll probably get something a bit different made up. Replaced all the clamps and some joiners. The fit is great, the hole for the pipe looks like it's supposed to be there.
