Thanks for the responses guys. I feel like such a tool now. Followed the instructions from the manual. I've done 4 or 5 oil changes on this bike already. My problem was dumping the full 6 (ish) Litres in rather than stopping at 5L and going from there. Which is precisely what I've done in the past. Just don't know what I was thinking. I guess the fact of the matter is I
wasn't thinking.
Syphoned some out and we're good now. For the record, synthetic oil doesn't taste one bit better than Dino oil
