First, good idea for a thread John. Maybe this will break the myth that the BX has a vulnerable hydro fan. No I have not broke the fan. I do not have any added protection for it. I also leave my MMM on a fair amount of the time because the BX has pretty good ground clearance with it on it unlike other SCUT's. It looks like to me it would be pretty hard to break on the newer BX's with the fan protector. People should also say how many hours they have on their BX. I have 177 hours.
