Oil leak in my 2008 1200 C
Well, my 2008 XL 1200 C started to leak oil from the rear cylinder, on the top
Is a small leak.
Im wondering : a) how I fix this, b) it is related to my mods?
My mods are: SE SP (with drilled core), and a PC III with a rich map, also the spark plugs show that the bike is running pretty ok, mostly on the rich side.
Well, the pic
Do you think that the Power Commander III USB had something to do with this leak? I do not ride hard the bike, has about 10,000 km on it, mostly on open roads (I was following the Dakar Rally during the summer).
note: Im in Argentina, we have 1 dealer, and is like 650 km from were Im right now... so Im quite  up with this... also this machine is exotic here so most indies have never seen a Harley in person in their lives...

I don't think that your mods have caused a problem.
Leaks in the rocker boxes are very common.
Is it just above the cylinder or the rocker cover on the very top??
Top cover is very easy to fix it yourself. Get new gaskets and a manual.
Bottom rocker box itself pretty involved. Check the manual and decide whether you want to do it.
Could also try torqueing up to spec to see if it fixes the problem before changing the gaskets.
Good luck.

I would say that is a rocker box leak for sure. Have your dealer fix it under warranty as there have been lots of 07s and up that the rocker box bolts are loose from the factory. they need to check it.
