It is best to. Mine shakes a good bit but even when I managed to max out the GL speedo, it stayed on. It did eventually vibrate so much that the latch loosened and fell down and I had to retighten it to be able to close the hood.
And about fitment. I had to move my latch, lower the hood stops and cut them to get them even lower, and move the fenders some. Fairly easy but takes a bit of time to get it all looking good.
