Definitely heard a tapping/ticking on the way home...A noise that was there before the rebuild. Pulled the valve cover off the 550... perfectly lubed, no signs of any damage. Broke the tach drive gear in the process. Told the bike to catch a boat to #$%*_offity_land. Grabbed a bear and started looking at craigslist for a GSXR or fz6R. Rash decisions have been made on my account due to a few too many beers. Hopefully tonight isn't one of those nights.
