E: Engine Oil leak at cylinder base


Well Known and Active Website User

After a 15-20 mile spin I always have a trickle of oil on the mag cover, left side (Rapide C)
I took the cover off and thoroughly cleaned the area then took the bike out again.
It does appear that it's coming front the base of the front cylinder and also a little on the oil filter housing.
Just wondering if maybe the head/barrel needs re-torqueing down.
Any help appreciated.

Check for oil under the fwd. cyl.'s exhaust nut. If it is wet, look at the intake valve's rocker oil fitting(234). An oil leak there, (I've seen) will run down the back of the cyl. then along the cylinder fins until drops down onto your mag. Also see another post here (Persistent Oil Leak) Good luck.

Most likely either the banjo seals on the breather pipe and/or the pushrod tube lower seals on the front cylinder.
