Posted May 17, 200916 yr Hi all my yzf750r uses about 300ml of oil every 170 miles or so, iknow they burn a bit, and i get a puff of black smoke when i rev it quite hard, but is this normal for one of these. its only done 21000 miles and im just checking before i decide to go and change the valve stem seals or see if its worn the rings(hopefully not rings)
May 18, 200916 yr Burning oil is quite common with the YZF`s and FZR`s. With the YZF750, its usually the valve stem seals, might be worth pulling it apart and checking your valve clearances at the same time. Although i`ve had a few 750`s, never had an issue with using oil, apart from the one that had a FZR1000 motor in it, that had to have the stem seals replaced as it had the same problem as yours.
