Are there currently any F4i undertails that don't require modification that clean up the rear of the bike? I'm not really comfortable cutting into the underside of my bike for the HotBodies
Also, anyone had any experience with these and how much modification it requires?

As far as chain guards go, my bike does not have one, is there any advantage to having one, other than aesthetics? Would it be worth it to buy one, such as the aluminum ones I keep seeing on eBay?

Thanks in advance
