I fired up my 99 Road King after a long cold winter and found about 1/8 of a cup of Tan colored oil dripped out after it had started and warmed up. After an hr the oil on the floor turned black. ANy idea why the change in color or what may have caused it. I assume the gasket blew as the bike made a farting noise after running it for 15 seconds almost a whooshing sound. It definitely is leaking on the lower left side mid center. Any info greatly appreciated, also gaskets from J&P high standard? Kit for about $40.00 tks
