Eddie thanks for the link, very helpful, I will never get anything done reading this lot.
Thanks Ted it all makes sense now, just expected it was the same as the Beta. I have only changed the oil for now as the seals are not leaking. I have seen what you mean now on a video via the link Eddie sent, I will look out for this next time, thanks again. Same in both legs on these by the looks. 300cc or ml. They said 7 weight - I have already bought 5 now.......
