Quite a bit.... for me.
1) Installed Hagons... This probably goes without saying, but the ride difference from the original Showas is absolutely night and day. Money well spent.
2) Swapped in a tach that was acquired from member: jamesb Thanks again Jimmy! I now know what I pretty much assumed before.... I redline nearly every shift.
3) Replaced the clock bulbs with green LED replacement bulbs from superbrightleds. Nice green glow now..... like it.
4) Dropped the exhaust so I could change oil and drop the oil pan... the pan hadn't been removed since I bought the bike in 12/14. No surprises, which is nice. Cleaned up the sludge... cleaned the sump screen... cleaned all of the caked grime off the pan exterior... reinstalled with a new OEM pan gasket. Reinstalled exhaust.
5) Fired it up for the first time in 2016.... rode about 20 miles.... no leaks. Very good, productive day.
