Drained out 50 weight oil and replaced with 10W40 Napa brand oil and 4 oz of Seafoam. Let bike idle for 20 minutes and exercised gears and clutch before taking it to the football stadium parking lot. Did seven miles worth of parking lot riding to free up the clutch and allow myself to shift between the different gears again. Did five miles on the road to get the bike up to 55mph.
