The Polisport shrouds lined up well, just as good as stock. Polisport may need to do some quality control though, my plastics were a bit scratched and mauled, this wouldn't matter if your adding a new graphics kit though.
I ordered the shrouds for my kx250f and they don't line up at all, I had to stretch the plastics out just to fit. they don't hug the gas tank either, kinda leave room for air to escape and that's always good! hopefully there durable.
