I just bought my bike a month ago it is a 2008 xb12Ss with 10,000 miles I noticed last night after cleaning it that it is leaking oil on the top back side of motor (rocker I am guessing) there is oil around the fan an on some of the wires an tubes up towards top of engine i cant really tell where it is coming from I am not a mechanic so i will be taking it to a bike shop.....was wondering if any one had to have new rocker gaskets put in by a shop an how much they are going to rape me for?[sad]
