Spot on. Either rings have gone, or crack/hole in piston head..Fuel shouldnt be getting through to your oil to that extent. Ive bought yet another Fazer cheap which was suffering with similar problems. Engine out, head stripped, pistons checked and yes piston 3 was cracked on the head. Not very common but unfortunately it does happen.. Simple enough job to change the piston but I just changed all 4 with new rings.. Runs a dream now.. Just 1000 other jobs left to do on it...
It's not a speed limit it's a target
