Hi guys, Just a question regarding my baby ZZR. I am finding that I am topping up oil a fair bit lately... Probably every 1000-1500 km's. Roughly that is could be more could be less.... Anyway, the bike isn't blowing black smoke or anything and goes very well from what my unmechanically minded brain sees. There are no leaks. It just seems that the engine is slowly burning it away. Would this be a normal occurance for bikes that age. It is a ZZR250 1992 Model, grey import. Thanking you all in advance for any assistance. Cheers THE PUP.
