I e always used br9eg and that?s what the manual says to use. But like I?ve said, for whatever reason, the mechanic, who by the way races for gasgas uk advised to use br8es! ������

If you are in Europe, the spark plug the manual says you should use is a NGK BR8EG. I wonder what owners manual you have, but for sure not the same I have.
If you are in the US, well, there may be a different owners manual though I see no reason for that.
