Hi .. I just screw up my Km to Miles .. It was in Km and my ride is normal , local , highway , the bike just drink it , no black smoke, no spot on the floor, The first time they open they engine was for a rocker going bad .. been replace and after the change some head gasket. I can see some trace of oil at the bottom of the cylinder... but just a trace ... One more thing .. my FXSTB 07 ...modify to stage3 do not use a drop of oil between oil change.(SE synt) Even my old FX 84 1/2 will use some time 1/4 pint between oil change ... the 110ci will use 2 pint ... at that rate soon I will not have to change oil ... It will do it himself ... The Dealers say is normal .... I have some doubt .. Just trying to see if the Engine is a lemon or this is a know issue .... Is it a good idea to change the muffler to reduce the heat in the catalyst and install a oil radiator .. I wanted to keep it ... I'm good to keep them for 25 years.
