I just installed an ASV brake and clutch lever....hopefully I won't have to replace these after every fall The instructions say that the stock dust covers can be used. But, if I leave that little dirt deflector on that the ASV's come with, the stock covers don't come close to being able to fit. Plus they look better without them. Those of you that have ASV levers, do you use the stock covers, or did you just pitch them? Are the stock dust covers even necessary?
