My 400ex run good,my plug is dark gray and I use DPR8Z sparks plug
The temp around is 68F to 86F and its colder the morning and evening
I run syntethic 10w40 oil
I want to know if I change the spark plug for a DPR9Z that is for long high speed if my 400ex will run colder?Or it will change anything??
