How hard is to install these guards on '03 R1?

Its really easy.....

2 ty-raps at the top,the stock rad retainign bolt at the bottom to remove and voila.

Just installed one on my 08. The fit is a little off. The tab that attaches the guard to the bottom radiator mount is positioned in such a way that the guard isn't able to be completely centered. There ends up being about a 1/2" inch gap on the left side. I was able to bend the tab slightly in order to take a few mm off the bias but it's still not completely centered. I'm sure that it'll do its job but for the price, I think you shouldn't have to manipulate anything.
