before things get too complicated, read up on the oil filter changes harley has made with regard to the various engines. the evo engine uses a different filter than a twin cam etc. and they mention the puking oil thru breather if the right filter isnt used..If you have a twin cam puking oil out you're air breather the oil pump is more then likely out of align.

lostgringo you did have a good point about the oil filter, if it was a evo with a 5 micron filter installed, it could restrict the oil flow and cause the carryover, but on a twin cam if the 30 micron filter was installed it would not be too restrictive, it just would not filter the oil as it needs to be for a twin cam.before things get too complicated, read up on the oil filter changes harley has made with regard to the various engines. the evo engine uses a different filter than a twin cam etc. and they mention the puking oil thru breather if the right filter isnt used..
