My 2002nightrain 76k has been flawless up till now.started drippong a little oil out if the breather and a rattle that sounds to b in the topof the motor. Yesterday when takeing off a little harer then normal the oil filler cap blew off. Any body have snt clues

 

Oil pressure is high, if it's coming out the breather and popping off the oil cap,
indicating too much oil. Check your level per the manual.

 

Sound's like it could be one of the cylinder head breathers. These are the hollow bolts that hold the air cleaner backing plate on. Probably should take both of them off and clean them out.

 

After the leak started i changed the oil and filter my self it has the right amount of oil

 

Excessive Blow-by (piston rings) or overfillled. Those two come to mind first.
Check Breather tubes also.
