hello, have 98 rkc evo/fuel inj...non-oil leak from cone area of engine /on brake side of bike/ from metal cone thru hole were wire exits the cone just below the timer cover...looks a melted plastic or goooo..like hard as nails stuff..difficult to remove but wd-40 works...i am original owner and bike has 12500 miles..bike maintained as per book by self..runs great..what is this stuff? what is inside timer cone that could melt away after 9 years? some type of gasket?

 

Sounds like something in the timing cover is melting, prob the protective coating for the wiring. I'd pull it down and take a looksee.

 

finished and answered on other link...look under timer cover change or author im

 

hope this helps if you can not find thread.
the 98 road king uses a thin round aluminum-type cover with a V-2 inscribed, this thin cover is held by "CLOSED END RIVETS" on the top + bottom to the round plate behind it that is made of thick metal..about 4 times thicker than the V-2 aluminum cover..this second thick cover is then held in place with two phillips head screws /one on the left the other on the right..on a 98 evo there will be no gasket if bike is original from the factory...any cover that you purchase will be round with 2 screws on the horizontal (one left / one right) some kits bring a gasket (just in case)--a replacement cover will not use rivets..
***by the way when you remove the 2 rivets/first plate and the 2 screw/second plate do not be surprised to find some biege goo/melted plastic this is the sensor,vas,fl part number 32448-95a $180 thru walk-up dealer or about $140 thru surdyke HD internet...this sensor is on a plate..the sensor and plate are a unit and are sold as such...if your bike is fuel injected the removal of this plate is straight forward and will not alter the timing..only one way to place it..get the service manual it will walk you through it..never..ever use normal rivets if you decide to re-use the old V-2 cover..closed end rivets are designed to be sealed--no metal--no water getting in the case ..dealer charges about 2 hours labor plus parts..
