Dear Emil,
If its blue smoke, your engine has blow by and needs an overhaul. Meaning,the oil is passing through the piston rings. You can rejet it with a size 85 or 90 unless you get a hiccup. Going 9kms to a liter is not so bad. Thats kinda good milege even for todays standards of EFI tech. Thanx for writing.
