Here's another link to a thread about the high fender mod on the 990. There are numerous threads like this out there: http://www.advrider.com/forums/showthread.php?t=296490

If I were you, I'd look at copying what people are doing to the 990Rs when the high fender is installed. Just avoid buying the brake lines for the ABS model. I did that originally, and there is no way that this will work.
As noted in my thread, I wanted to change away from the old standard setup that used the crossover link that ran on top of the low front fender because that can create a bit of a problem: http://advrider.com/forums/showthread.php?t=667236
I immediately started researching how to change that original setup after watching Lost Rider's crash. Imagine if that had happened on a surface where the front tire had a little more grip.
