bad rings and or bad valves what color are the plugs that will tell you alot look at the plugs then find the page in your manual that tells you whats up. They are usaly the colored pages in some manuals. If you have the head off you could put a little oil in the top of the clys if it leaks thru your oiler ring is gone if the oil holds then its more than likly to be in your head and you valve guides or seals.
Good luck
