mud and dirt is everywhere. if you dont do this now and again bolts will seize up. actually one already was, and the riv-nut was spinning in the subframe.
things didnt feel right on the way home last weekend, and im pretty sure i discovered why:
cracked spark plug. dont really know how this happened, the guys at hermy's BMW have seen it happen, but infrequently. the plugs (2 plugs for one cylinder, awesome!) are only about 2000 miles old. this is the secondary plug, so the bike ran rough. i wonder how it would have run if the primary failed?
