[QUOTE] Thanks al, yep I just found a small stamp near the oil level window that has the qty in ml's read at 4500, thanks to you all for your help and replies, cheers.[/QUOTE] Don't go tipping 4.5 litres in there all at once. You probably won't need to refill it with that much. More likely it'll be about 1.litre less. Manufacturers often specify several different oil refill levels, my ZX12R even had all 3 stamped on the casing.. How much was required for a complete refill after an engine build, how much was required with and also without a filter change. 4.5 litres sounds like a complete refill, but that's an oil cooled model, so perhaps it has a very large capacity. I'd be inclined to start small and work your way up as suggested by other posters, and also, if it's oil cooled, probably worth getting your hands on a manual and finding out if a drain from the sump is all taht is required or if there are additional drain points as well. Nev.. '07 XB12X Yeah sweet got that but it did inevitably take roughly about that much albeit not poured in in one go. regards olley
