If i only have my spark arrestor out but my map is for spark arrestor out lid off and trinity intake will it be running really rich if i leave the lid on i dont even have an aftermarket intake so im sure it will be rich but i am riding really dusty conditions right now so im wondering if i should just leave my lid on or would it be better to buy an intake and leave the lid on or will it survive without the lid on even in the dusty conditions??
