i the 400ex manual it says the standard spark plug is DPR8Z
then there is another plug that says it is for extended high speed riding which is a DPR9Z
what determines the high speed riding is it for mostly dune riding?
i ride mostly trails and am going to go with the standard plug but i was just wondering
